La version la plus récente disponible s'appelle "Nightly Builds" et offre les dernières fonctionnalités et mises à jour non testées. La version "Aurora" a jusqu'à six semaines de retard sur "Nightly" et offre des fonctionnalités qui ont subi des tests de base. Depuis la version 35, le canal "Aurora" a été renommé en canal "Developer Edition".[4][5] La chaîne "Beta" a jusqu'à six semaines de retard sur la version "Aurora", jusqu'à environ douze semaines par rapport à la version la plus récente "Nightly". Le canal "Beta" offre une stabilité améliorée par rapport aux versions "Nightly" et est le premier jalon de développement qui a le logo "Firefox". "Release" est la version officielle actuelle de Firefox. La numérotation de version de Gecko est la même que le numéro de version de Firefox, commençant par 5.0 sur Firefox 5.\n\nL'objectif déclaré de ce processus plus rapide est de fournir plus rapidement de nouvelles fonctionnalités aux utilisateurs.[6] Ce cycle de publication accéléré a été critiqué par les utilisateurs, car il rompait souvent la compatibilité des modules complémentaires,[7] ainsi que ceux qui croient que Firefox essayait simplement d'augmenter son numéro de version pour le comparer à d'autres navigateurs tels que Google Chrome.[8]\n\nFirefox 5 à 9\nFirefox 5 est sorti le 21 juin 2011,[9] trois mois après la sortie majeure de Firefox 4. Firefox 5 est la première version du nouveau plan de version rapide de Mozilla, correspondant au calendrier de publication rapide de Google Chrome et aux incréments de numéro de version rapides.[10] Firefox 5 a considérablement amélioré la vitesse des tâches liées au Web, telles que le chargement de pages avec des listes déroulantes ou MathML. Mozilla a également intégré la norme WebM vidéo HTML5 dans le navigateur, permettant la lecture de vidéos WebM.[11]\n\nFirefox 6 est sorti le 16 août 2011, introduisant un gestionnaire d'autorisations, une nouvelle mise en évidence de la barre d'adresse (le nom de domaine est noir tandis que le reste de l'URL est gris[12]), rationalisant l'apparence du bloc d'identité du site, un temps de démarrage plus rapide, un compilateur JavaScript ScratchPad et de nombreuses autres nouvelles fonctionnalités. Cette mise à jour a également apporté la tristement célèbre fonctionnalité qui empêchait l'exécution de JavaScript entré dans la barre d'adresse.[13]\n\nFirefox 7 est sorti le 27 septembre 2011,[14] et utilise jusqu'à 50% de RAM en moins que Firefox 4 grâce au projet MemShrink visant à réduire l'utilisation de la mémoire de Firefox.[15][16][17]\n\nFirefox 7.0.1 est sorti quelques jours plus tard, corrigeant un problème rare, mais sérieux, avec des modules complémentaires non détectés par le navigateur.[18] Certaines URL sont coupées dans la barre d'adresse, de sorte que le schéma "http: //" n'apparaît plus, mais "https: //" est toujours affiché. Les barres obliques de fin sur les domaines sont également masquées, par exemple: https://www.example.org/ devient https://www.example.org.[12][19]\n\nFirefox 8 est sorti le 8 novembre 2011[20] et informe les utilisateurs sur les modules complémentaires déjà installés. Lors de l'installation, une boîte de dialogue a invité les utilisateurs à activer ou désactiver les modules complémentaires. Les modules complémentaires installés par des programmes tiers étaient désactivés par défaut, mais les modules complémentaires installés par l'utilisateur étaient activés par défaut. Mozilla a jugé que les modules complémentaires installés par des tiers étaient problématiques, en supprimant le contrôle de l'utilisateur, en retard sur la compatibilité et les mises à jour de sécurité, en ralentissant le démarrage de Firefox et le temps de chargement des pages, et en encombrant l'interface avec des barres d'outils inutilisées.[21]\n\nFirefox 9 est sorti le 20 décembre 2011, comprend diverses nouvelles fonctionnalités telles que l'inférence de type, qui augmente les performances JavaScript jusqu'à 30%, une intégration améliorée du thème pour Mac OS X Lion, une navigation par glissement à deux doigts pour Mac OS X Lion, ajoutée prise en charge de l'interrogation de l'état Ne pas suivre via JavaScript, ajout de la prise en charge de l'extension de police, prise en charge améliorée du dépassement de texte, prise en charge des normes améliorée pour HTML5, MathML et CSS, et résolution de plusieurs problèmes de sécurité.

une API plein écran et amélioré les performances WebGL, la prise en charge des transformations CSS 3D et de l'anti-aliasing dans la norme WebGL pour les graphiques 3D à accélération matérielle. Ces mises à jour WebGL signifient que des animations de sites et d'applications Web plus complexes peuvent être rendues de manière fluide dans Firefox et que les développeurs peuvent animer des objets 2D en 3D sans plug-ins.[39][40] Il a également introduit un nouvel inspecteur de style CSS, qui permet aux utilisateurs de vérifier la structure d'un site et de modifier le CSS sans quitter le navigateur.[37] Firefox 10 a supposé que tous les modules complémentaires créés pour au moins Firefox 4 étaient compatibles. Le développeur du module complémentaire peut alerter Mozilla que le module complémentaire est incompatible, annulant la compatibilité avec la version 10 ou ultérieure. Cette nouvelle règle ne s'applique pas non plus aux thèmes.[41]\n\nFirefox 10 ESR est le premier Version de support étendu (ESR) comme précédemment le 10 janvier 2012, où la Fondation Mozilla a annoncé la disponibilité d'une version ESR de Firefox.[42] Firefox ESR est destiné aux groupes qui déploient et maintiennent l'environnement de bureau dans de grandes organisations telles que les universités et autres écoles, les gouvernements de comté ou de ville et les entreprises. Pendant le cycle prolongé, aucune nouvelle fonctionnalité ne sera ajoutée à Firefox ESR; Seules les vulnérabilités de sécurité à haut risque / impact élevé ou les problèmes de stabilité majeurs seront corrigés.[43]\n\nFirefox 11 est sorti le 13 mars 2012. Firefox 11 a introduit de nombreuses nouvelles fonctionnalités, notamment la migration des signets et de l'historique depuis Google Chrome,[44] Services intégrés SPDY, inclinaison de l'inspecteur de page (vue 3D), synchronisation des modules complémentaires, contrôles vidéo HTML5 repensés et éditeur de style (CSS).[45] La mise à jour a également corrigé de nombreux bogues et amélioré les outils de développement.[46]\n\nFirefox 12 est sorti le 24 avril 2012. Firefox 12 a introduit quelques nouvelles fonctionnalités, mais il a apporté de nombreux changements et a jeté les bases des futures versions. Firefox 12 pour Windows a ajouté le service de maintenance de Mozilla qui peut mettre à jour Firefox vers une version plus récente sans invite UAC.[47] Il a également ajouté des numéros de ligne dans la "Source de la page" et une recherche centrée dans les résultats de la page. Il y a eu 89 améliorations de la console Web, du bloc-notes, de l'éditeur de style, de l'inspecteur de page, de l'inspecteur de style, de la vue HTML et de la vue 3D de l'inspecteur de page (inclinaison).[48] De nombreux bugs ont été corrigés, ainsi que de nombreux autres changements mineurs sous le capot.[49][50] Firefox 12 est la dernière version prenant en charge Windows 2000 et Windows XP RTM & SP1.[51][52]\n\nFirefox 13 est sorti le 5 juin 2012.[53] À partir de cette version, la prise en charge de Windows était exclusivement pour Windows XP SP2 / SP3, Windows Vista et Windows 7. Firefox 13 ajoute et met à jour plusieurs fonctionnalités, telles qu'un nouvel onglet mis à jour[54] et la page de l'onglet d'accueil.[55] La nouvelle page à onglet mise à jour est une fonctionnalité similaire à la numérotation abrégée déjà présente dans Opera, Google Chrome, Apple Safari et Internet Explorer. La nouvelle page à onglet affichera neuf des sites Web les plus visités de l'utilisateur, ainsi qu'une image en cache. En plus du nouvel onglet et de la page d'accueil mis à jour, Mozilla a ajouté un nettoyeur / réinitialisation de profil utilisateur, des temps de suspension réduits et implémenté des onglets à la demande.[56] Le nettoyeur / réinitialisation du profil utilisateur permet aux utilisateurs de corriger les erreurs et les problèmes de Firefox qui peuvent survenir.[57] Les onglets à la demande de Mozilla restaure les onglets qui étaient ouverts lors de la session précédente, mais garderont les onglets déchargés jusqu'à ce que l'utilisateur demande à afficher la page.[58]\n\nFirefox 14 est sorti le 26 juin 2012 pour les appareils mobiles uniquement, juste en dehors du calendrier de publication régulier du navigateur Web.[59] Afin de synchroniser les numéros de version des versions bureau et mobile de Firefox, Mozilla a décidé de publier la version 14.0.1 pour mobile et bureau le 17 juillet 2012, au lieu de Firefox 14 version 14.0 pour le bureau et la version 14.0.1 pour appareils mobiles.[59]\n\nFirefox 14 introduit un nouveau détecteur de blocage (similaire à la façon dont Mozilla collecte actuellement d'autres données) qui permet à Mozilla de collecter, d'analyser et d'identifier la cause du blocage / blocage du navigateur. Mozilla utilise ces informations pour améliorer la réactivité de Firefox pour les versions futures.[60] En plus de lutter contre les erreurs de blocage et de non-réponse qui se produisent à cause de Firefox, Mozilla a implémenté l'activation opt-in pour les plugins tels que Flash et Java. Mozilla souhaite réduire les problèmes potentiels qui pourraient survenir suite à l'utilisation indésirable d'applications tierces (malware, gel, etc.).[61]\n\nFirefox 15 est sorti le 28 août 2012 avec un outil de développement «Responsive Design View»,[62] ajoute la prise en charge du format audio Opus et ajoute le support PDF natif préliminaire (désactivé par défaut).[63]\n\nFirefox 15 a introduit des mises à jour silencieuses, une mise à jour automatique qui mettra à jour Firefox vers la dernière version sans avertir l'utilisateur,[64] une fonctionnalité que les navigateurs Web Google Chrome et Internet Explorer 8 et supérieur ont déjà implémentée,[65][66] bien que l'utilisateur ait pu désactiver cette fonction.[67] Le temps de démarrage de Firefox 15 a été amélioré pour les utilisateurs de Windows.[68]\n\nFirefox 16 est sorti le 9 octobre 2012, corrigeant les bogues exceptionnels des nouvelles fonctionnalités de Mac OS X Lion. Des améliorations ont été apportées à la vitesse de démarrage lorsqu'un utilisateur souhaite restaurer une session précédente.[69] La prise en charge de l'affichage des fichiers PDF en ligne a été ajoutée au placement d'un plugin. La prise en charge des applications Web a été ajoutée. Le format audio Opus est désormais activé par défaut.[70]\n\nLe déploiement de la révision 16.0.0 de Firefox 16 a été arrêté le 10 octobre 2012, après que Mozilla a détecté une faille de sécurité et recommandé de passer à la version 15.0.1 jusqu'à ce que le problème soit résolu.[71] La faille de sécurité a été corrigée dans la version 16.0.1, qui a été publiée le jour suivant, le 11 octobre 2012.[72]\n\n\n\n\nHistorique des versions de Firefox 10–16\n\n\n\nVersion\n\nDate de sortie[23]\n\nType de version et faits saillants[t 1]\n\n\n\n10,0\n\n31 janvier 2012\n\nVersion officielle de

An important aspect of Firefox ESR 52.0 is that it is the first ESR version based on Firefox Electrolysis (Firefox 48) code base. Firefox 52 added support for WebAssembly (while disabled in Firefox ESR 52), an emerging standard that brings near-native performance to Web-based games, apps, and software libraries without the use of plugins; automatic captive portal detection, for easier access to Wi-Fi hotspots; user warnings for insecure HTTP pages with logins (desktop); and display of media controls to pause or resume playback on the Android notification bar.[300][301] Firefox 52 dropped support for NPAPI plugins like Microsoft Silverlight and Java with the exception of Adobe Flash Player (except the ESR version which still supports NPAPI).[302]\n\nFirefox 53 was released on April 19, 2017 for both desktop and Android. Starting with Firefox 53, Microsoft Windows support is exclusively for Windows 7 and above. Among the many additions are: improved graphics stability for Windows users with the addition of compositor process separation, light and dark "compact" themes available, based on the Firefox Developer Edition theme, removal of support for 32-bit macOS and Linux support for processors older than Pentium 4 and AMD Opteron; new visual design for audio and video controls, support for WebM video with alpha compositing, which allows playing videos with transparent backgrounds (desktop), Reader Mode displaying estimated reading time for the page (desktop and Android), and enabling two columns tabs setting in portrait mode (Android).[303][304]\n\nFirefox 54 was released on June 13, 2017 for both desktop and Android. Among the many additions are: simplifying the download button and download status panel, added support for multiple content processes, the ability to create and save custom devices in Responsive web design mode (desktop), improved audio and video playback in the browser, and improved bookmarks sync performance (Android).[305][306]\n\nFirefox 55 was released on August 8, 2017 for both desktop and Android. Among the many additions are: the launch of Windows support for WebVR, bringing immersive experiences to the web, options that let users optimize recent performance improvements, simplification of the installation process with a streamlined Windows stub installer, improvements to address bar functionality, simplification of printing from Reader Mode (desktop), and the option for accessibility settings to respect the system's set font size when displaying web pages (Android). This is also the last version to support Android Ice Cream Sandwich.[307][308]\n\nFirefox 56 was released on September 28, 2017 for both desktop and Android. Among the many additions are: a new layout for the "Preferences" page, the launch of Firefox Screenshots, support for address form autofill, hardware acceleration for AES-GCM, update of the Safe Browsing protocol to version 4, improved security or verifying update downloads (desktop), improvement of support for WebExtensions, and the end of support for Adobe Flash (Android). Starting with this version, Android support is exclusively for Android Jelly Bean and above.[309][310]\n\nAnother change was the introduction of the mozlz4 format, a proprietary variant of the lz4 compression format (.mozlz4 and .jsonlz4 file extensions instead of .json.lz4 as per unix/linux standard). Session data is stored in the lz4 format instead of plain text. Firefox 56 cannot recognize the legacy plain text session files, only the lz4-encoded ones.\n\nFirefox 57 was released on November 14, 2017 for desktop and Android with the name Firefox Quantum.[311] ZDNet dubbed it a "comeback" following years of falling market share against Google Chrome.[312][313] The release included a new interface design, codenamed "Photon", and a new rendering engine almost twice as fast as the previous one used.[311][312][314] One of the largest visual changes in Photon was the removal of the search box from the address bar. Firefox 57 no longer supports legacy add-ons using XUL technologies.[315][316][317] That same day, Mozilla announced that Google would be the default search engine in the US and Canada, a departure from Yahoo, which had been the default search engine in the US and Canada since 2014.[318]\n\nFirefox 58 was released on January 23, 2018 for desktop and Android. Among the additions were: support for credit card autofill, the drop of support for user profiles in previous versions of Firefox, a warning to alert users and site owners of planned security changes to sites affected by the gradual distrust plan for the Symantec certificate authority (desktop), full screen bookmark management with folder support, support for FLAC (Free Lossless Audio Codec) playback, the ability to change the status bar color in themes, and removal of the Firefox Search widget from the home screen (Android).[319][320]\n\nFirefox 59 was released on March 13, 2018 for desktop and Android. Among the additions were: faster load times and improved graphics, improved Real-Time Communications (RTC) capabilities, additional features for Firefox Screenshots, support for W3C specs for pointer events, Private Browsing Mode's removal of path information from referrers to prevent cross-site tracking (desktop), and the addition of Firefox as an Assist app, support for HLS (HTTP Live Streaming) playback for improved compatibility with video sites, and removal of the "about:" page.[321][322]\n\n\n\n\nRelease history of Firefox 52–59\n\n\n\nVersion\n\nRelease date[23]\n\nRelease type and highlights[t 1]\n\n\n\n52.0\n\nMarch 7, 2017\n\nOfficial Firefox 52.0 release.[300][301]\n\nFirst release to implement WebAssembly.\nAdded support for WebAssembly, an emerging standard that brings near-native performance to Web-based games, apps, and software libraries without the use of plugins.\nAdded automatic captive portal detection, for easier access to Wi-Fi hotspots. When accessing the Internet via a captive portal, Firefox will alert users and open the portal login page in a new tab.\nEnabled multi-process Firefox for Windows users with touch screens\nAdded user warnings for non-secure HTTP pages with logins. Firefox now displays a "This connection is not secure" message when users click into the username and password fields on pages that don't use HTTPS.\nImplemented the Strict Secure Cookies specification which forbids insecure HTTP sites from setting cookies with the "secure" attribute. In some cases, this will prevent an insecure site from setting a cookie with the same name as an existing "secure" cookie from the same base domain.\nEnhanced Sync to allow users to send and open tabs from one device to another.\nImproved text input for third-party keyboard layouts on Windows. This will address some keyboard layouts that:\n\nhave chained dead keys.\ninput two or more characters with a non-printable key or a dead key sequence.\ninput a character even when a dead key sequence failed to compose a character.\n\n\nRemoved support for Netscape Plugin API (NPAPI) plugins other than Flash. Silverlight, Java, Acrobat and the like are no longer supported.\nRemoved Battery Status API to reduce fingerprinting of users by trackers.\nImproved experience for downloads:\n\nNotification in the toolbar when a download fails.\nQuick access to five most recent downloads rather than three.\nLarger buttons for canceling and restarting downloads.\n\n\nDisplaying (but allowing users to override) an "Untrusted Connection" error when encountering SHA-1 certificates that chain up to a root certificate included in Mozilla's CA Certificate Program.

Windows (since version 42).[548][[[[citation needed]\n\nMozilla made Firefox for 64-bit Linux a priority with the release of Firefox 4, labeling it as tier 1 priority.[[[[citation needed][549] Since being labeled tier 1, Mozilla has been providing official 64-bit releases for its browser for Linux.[550][551] Vendor-backed 64-bit support has existed for Linux distributions such as Novell/SUSE Linux, Red Hat Enterprise Linux, and Ubuntu prior to Mozilla's 64-bit support, even though vendors were faced with the challenge of having to turn off the 64-bit JIT compiler due to its instability prior to Firefox 4.[552][553]\n\nThe official releases of Firefox for macOS are universal builds that include both 32-bit and 64-bit versions of the browser in one package, and have been this way since Firefox 4. A typical browsing session uses a combination of the 64-bit browser process and a 32-bit plugin process, because some popular plugins still are 32-bit.[554] As of April 19, 2017, Firefox 53 has dropped support for 32-bit macOS.[555]\n\nThe 32-bit and 64-bit versions of Windows can be used to run 32-bit Firefox.[[[[citation needed] In late 2012, Mozilla announced 64-bit Windows builds would be stopped[556] but later reversed the decision.[557] As of April 2015[update], 64-bit Windows builds are available as 38.0 Beta[558] and newer. 64-bit builds for Windows are officially supported as of November 2015 with the release of Firefox 42. All NPAPI plugins except Adobe Flash Player are blacklisted and unsupported on both 32-bit and 64-bit versions.[559]\n\nOther CPU architectures\nBesides x86, Firefox also supported other CPU architectures including ARMv7, SPARC, PowerPC, and 68k on different tiers.[560] Mozilla terminated support for PowerPC-based Macintosh computers with Firefox 3.6, but a third-party project known as TenFourFox ported several newer versions of Firefox, the latest being based on Firefox 45 ESR.\n\nMozilla Firefox timeline\n\n\n\n\nRelease compatibility\n\n\n\n\nSystème opérateur\n\nLatest stable

À partir de la version 5.0, un cycle de publication rapide a été mis en place, aboutissant à une nouvelle version majeure. toutes les six semaines. Cela s'est progressivement accéléré à la fin de 2019, de sorte que les nouvelles versions majeures se produisent sur des cycles de quatre semaines à partir de 2020.[3] Firefox 85 est la dernière version, sortie le 26 janvier 2021.","Contenus\nToggleVersions actuelles et futuresVersions officielles actuelles prises en chargeVersions de test actuellement prises en chargeFutures versions officiellesPremières versionsLibérations rapidesFirefox 5 à 9Firefox 10 à 16Firefox 17 à 23Firefox 24 through 30Firefox 31 through 37Firefox 38 through 44Firefox 45 through 51Firefox 52 through 59Firefox 60 through 67Firefox 68 through 77Firefox 78 through 90Firefox 91 through 99CPU architecturesx86 familyOther CPU architecturesMozilla Firefox timelineRelease compatibilitySee alsoExplanatory notesReferencesFurther readingExternal links\nVersions actuelles et futures","Versions officielles actuelles prises en charge","Versions de test actuellement prises en charge","Futures versions officielles","Rapide","ESR","Premières versions\nLibérations rapides\nEn avril 2011, le processus de développement a été divisé en plusieurs «canaux», chacun travaillant sur une construction à un stade de développement différent. La version la plus récente disponible s'appelle "Nightly Builds" et offre les dernières fonctionnalités et mises à jour non testées. La version "Aurora" a jusqu'à six semaines de retard sur "Nightly" et offre des fonctionnalités qui ont subi des tests de base. Depuis la version 35, le canal "Aurora" a été renommé en canal "Developer Edition".[4][5] La chaîne "Beta" a jusqu'à six semaines de retard sur la version "Aurora", jusqu'à environ douze semaines par rapport à la version la plus récente "Nightly". Le canal "Beta" offre une stabilité améliorée par rapport aux versions "Nightly" et est le premier jalon de développement qui a le logo "Firefox". "Release" est la version officielle actuelle de Firefox. La numérotation de version de Gecko est la même que le numéro de version de Firefox, commençant par 5.0 sur Firefox 5.","L'objectif déclaré de ce processus plus rapide est de fournir plus rapidement de nouvelles fonctionnalités aux utilisateurs.[6] Ce cycle de publication accéléré a été critiqué par les utilisateurs, car il rompait souvent la compatibilité des modules complémentaires,[7] ainsi que ceux qui croient que Firefox essayait simplement d'augmenter son numéro de version pour le comparer à d'autres navigateurs tels que Google Chrome.[8]","Firefox 5 à 9\nFirefox 5 est sorti le 21 juin 2011,[9] trois mois après la sortie majeure de Firefox 4. Firefox 5 est la première version du nouveau plan de version rapide de Mozilla, correspondant au calendrier de publication rapide de Google Chrome et aux incréments de numéro de version rapides.[10] Firefox 5 a considérablement amélioré la vitesse des tâches liées au Web, telles que le chargement de pages avec des listes déroulantes ou MathML. Mozilla a également intégré la norme WebM vidéo HTML5 dans le navigateur, permettant la lecture de vidéos WebM.[11]","Firefox 6 est sorti le 16 août 2011, introduisant un gestionnaire d'autorisations, une nouvelle mise en évidence de la barre d'adresse (le nom de domaine est noir tandis que le reste de l'URL est gris[12]), rationalisant l'apparence du bloc d'identité du site, un temps de démarrage plus rapide, un compilateur JavaScript ScratchPad et de nombreuses autres nouvelles fonctionnalités. Cette mise à jour a également apporté la tristement célèbre fonctionnalité qui empêchait l'exécution de JavaScript entré dans la barre d'adresse.[13]","Firefox 7 est sorti le 27 septembre 2011,[14] et utilise jusqu'à 50% de RAM en moins que Firefox 4 grâce au projet MemShrink visant à réduire l'utilisation de la mémoire de Firefox.[15][16][17]","Firefox 7.0.1 est sorti quelques jours plus tard, corrigeant un problème rare, mais sérieux, avec des modules complémentaires non détectés par le navigateur.[18] Certaines URL sont coupées dans la barre d'adresse, de sorte que le schéma "http: //" n'apparaît plus, mais "https: //" est toujours affiché. Les barres obliques de fin sur les domaines sont également masquées, par exemple: https://www.example.org/ devient https://www.example.org.[12][19]","Firefox 8 est sorti le 8 novembre 2011[20] et informe les utilisateurs sur les modules complémentaires déjà installés. Lors de l'installation, une boîte de dialogue a invité les utilisateurs à activer ou désactiver les modules complémentaires. Les modules complémentaires installés par des programmes tiers étaient désactivés par défaut, mais les modules complémentaires installés par l'utilisateur étaient activés par défaut. Mozilla a jugé que les modules complémentaires installés par des tiers étaient problématiques, en supprimant le contrôle de l'utilisateur, en retard sur la compatibilité et les mises à jour de sécurité, en ralentissant le démarrage de Firefox et le temps de chargement des pages, et en encombrant l'interface avec des barres d'outils inutilisées.[21]","Firefox 9 est sorti le 20 décembre 2011, comprend diverses nouvelles fonctionnalités telles que l'inférence de type, qui augmente les performances JavaScript jusqu'à 30%, une intégration améliorée du thème pour Mac OS X Lion, une navigation par glissement à deux doigts pour Mac OS X Lion, ajoutée prise en charge de l'interrogation de l'état Ne pas suivre via JavaScript, ajout de la prise en charge de l'extension de police, prise en charge améliorée du dépassement de texte, prise en charge des normes améliorée pour HTML5, MathML et CSS, et résolution de plusieurs problèmes de sécurité.

Ces mises à jour WebGL signifient que des animations de sites et d'applications Web plus complexes peuvent être rendues de manière fluide dans Firefox et que les développeurs peuvent animer des objets 2D en 3D sans plug-ins.[39][40] Il a également introduit un nouvel inspecteur de style CSS, qui permet aux utilisateurs de vérifier la structure d'un site et de modifier le CSS sans quitter le navigateur.[37] Firefox 10 a supposé que tous les modules complémentaires créés pour au moins Firefox 4 étaient compatibles. Le développeur du module complémentaire peut alerter Mozilla que le module complémentaire est incompatible, annulant la compatibilité avec la version 10 ou ultérieure. Cette nouvelle règle ne s'applique pas non plus aux thèmes.[41]","Firefox 10 ESR est le premier Version de support étendu (ESR) comme précédemment le 10 janvier 2012, où la Fondation Mozilla a annoncé la disponibilité d'une version ESR de Firefox.[42] Firefox ESR est destiné aux groupes qui déploient et maintiennent l'environnement de bureau dans de grandes organisations telles que les universités et autres écoles, les gouvernements de comté ou de ville et les entreprises. Pendant le cycle prolongé, aucune nouvelle fonctionnalité ne sera ajoutée à Firefox ESR; Seules les vulnérabilités de sécurité à haut risque / impact élevé ou les problèmes de stabilité majeurs seront corrigés.[43]","Firefox 11 est sorti le 13 mars 2012. Firefox 11 a introduit de nombreuses nouvelles fonctionnalités, notamment la migration des signets et de l'historique depuis Google Chrome,[44] Services intégrés SPDY, inclinaison de l'inspecteur de page (vue 3D), synchronisation des modules complémentaires, contrôles vidéo HTML5 repensés et éditeur de style (CSS).[45] La mise à jour a également corrigé de nombreux bogues et amélioré les outils de développement.[46]","Firefox 12 est sorti le 24 avril 2012. Firefox 12 a introduit quelques nouvelles fonctionnalités, mais il a apporté de nombreux changements et a jeté les bases des futures versions. Firefox 12 pour Windows a ajouté le service de maintenance de Mozilla qui peut mettre à jour Firefox vers une version plus récente sans invite UAC.[47] Il a également ajouté des numéros de ligne dans la "Source de la page" et une recherche centrée dans les résultats de la page. Il y a eu 89 améliorations de la console Web, du bloc-notes, de l'éditeur de style, de l'inspecteur de page, de l'inspecteur de style, de la vue HTML et de la vue 3D de l'inspecteur de page (inclinaison).[48] De nombreux bugs ont été corrigés, ainsi que de nombreux autres changements mineurs sous le capot.[49][50] Firefox 12 est la dernière version prenant en charge Windows 2000 et Windows XP RTM & SP1.[51][52]","Firefox 13 est sorti le 5 juin 2012.[53] À partir de cette version, la prise en charge de Windows était exclusivement pour Windows XP SP2 / SP3, Windows Vista et Windows 7. Firefox 13 ajoute et met à jour plusieurs fonctionnalités, telles qu'un nouvel onglet mis à jour[54] et la page de l'onglet d'accueil.[55] La nouvelle page à onglet mise à jour est une fonctionnalité similaire à la numérotation abrégée déjà présente dans Opera, Google Chrome, Apple Safari et Internet Explorer. La nouvelle page à onglet affichera neuf des sites Web les plus visités de l'utilisateur, ainsi qu'une image en cache. En plus du nouvel onglet et de la page d'accueil mis à jour, Mozilla a ajouté un nettoyeur / réinitialisation de profil utilisateur, des temps de suspension réduits et implémenté des onglets à la demande.[56] Le nettoyeur / réinitialisation du profil utilisateur permet aux utilisateurs de corriger les erreurs et les problèmes de Firefox qui peuvent survenir.[57] Les onglets à la demande de Mozilla restaure les onglets qui étaient ouverts lors de la session précédente, mais garderont les onglets déchargés jusqu'à ce que l'utilisateur demande à afficher la page.[58]","Firefox 14 est sorti le 26 juin 2012 pour les appareils mobiles uniquement, juste en dehors du calendrier de publication régulier du navigateur Web.[59] Afin de synchroniser les numéros de version des versions bureau et mobile de Firefox, Mozilla a décidé de publier la version 14.0.1 pour mobile et bureau le 17 juillet 2012, au lieu de Firefox 14 version 14.0 pour le bureau et la version 14.0.1 pour appareils mobiles.[59]","Firefox 14 introduit un nouveau détecteur de blocage (similaire à la façon dont Mozilla collecte actuellement d'autres données) qui permet à Mozilla de collecter, d'analyser et d'identifier la cause du blocage / blocage du navigateur. Mozilla utilise ces informations pour améliorer la réactivité de Firefox pour les versions futures.[60] En plus de lutter contre les erreurs de blocage et de non-réponse qui se produisent à cause de Firefox, Mozilla a implémenté l'activation opt-in pour les plugins tels que Flash et Java. Mozilla souhaite réduire les problèmes potentiels qui pourraient survenir suite à l'utilisation indésirable d'applications tierces (malware, gel, etc.).[61]","Firefox 15 est sorti le 28 août 2012 avec un outil de développement «Responsive Design View»,[62] ajoute la prise en charge du format audio Opus et ajoute le support PDF natif préliminaire (désactivé par défaut).[63]","Firefox 15 a introduit des mises à jour silencieuses, une mise à jour automatique qui mettra à jour Firefox vers la dernière version sans avertir l'utilisateur,[64] une fonctionnalité que les navigateurs Web Google Chrome et Internet Explorer 8 et supérieur ont déjà implémentée,[65][66] bien que l'utilisateur ait pu désactiver cette fonction.[67] Le temps de démarrage de Firefox 15 a été amélioré pour les utilisateurs de Windows.[68]","Firefox 16 est sorti le 9 octobre 2012, corrigeant les bogues exceptionnels des nouvelles fonctionnalités de Mac OS X Lion. Des améliorations ont été apportées à la vitesse de démarrage lorsqu'un utilisateur souhaite restaurer une session précédente.[69] La prise en charge de l'affichage des fichiers PDF en ligne a été ajoutée au placement d'un plugin. La prise en charge des applications Web a été ajoutée. Le format audio Opus est désormais activé par défaut.[70]","Le déploiement de la révision 16.0.0 de Firefox 16 a été arrêté le 10 octobre 2012, après que Mozilla a détecté une faille de sécurité et recommandé de passer à la version 15.0.1 jusqu'à ce que le problème soit résolu.[71] La faille de sécurité a été corrigée dans la version 16.0.1, qui a été publiée le jour suivant, le 11 octobre

An important aspect of Firefox ESR 52.0 is that it is the first ESR version based on Firefox Electrolysis (Firefox 48) code base. Firefox 52 added support for WebAssembly (while disabled in Firefox ESR 52), an emerging standard that brings near-native performance to Web-based games, apps, and software libraries without the use of plugins; automatic captive portal detection, for easier access to Wi-Fi hotspots; user warnings for insecure HTTP pages with logins (desktop); and display of media controls to pause or resume playback on the Android notification bar.[300][301] Firefox 52 dropped support for NPAPI plugins like Microsoft Silverlight and Java with the exception of Adobe Flash Player (except the ESR version which still supports NPAPI).[302]","Firefox 53 was released on April 19, 2017 for both desktop and Android. Starting with Firefox 53, Microsoft Windows support is exclusively for Windows 7 and above. Among the many additions are: improved graphics stability for Windows users with the addition of compositor process separation, light and dark "compact" themes available, based on the Firefox Developer Edition theme, removal of support for 32-bit macOS and Linux support for processors older than Pentium 4 and AMD Opteron; new visual design for audio and video controls, support for WebM video with alpha compositing, which allows playing videos with transparent backgrounds (desktop), Reader Mode displaying estimated reading time for the page (desktop and Android), and enabling two columns tabs setting in portrait mode (Android).[303][304]","Firefox 54 was released on June 13, 2017 for both desktop and Android. Among the many additions are: simplifying the download button and download status panel, added support for multiple content processes, the ability to create and save custom devices in Responsive web design mode (desktop), improved audio and video playback in the browser, and improved bookmarks sync performance (Android).[305][306]","Firefox 55 was released on August 8, 2017 for both desktop and Android. Among the many additions are: the launch of Windows support for WebVR, bringing immersive experiences to the web, options that let users optimize recent performance improvements, simplification of the installation process with a streamlined Windows stub installer, improvements to address bar functionality, simplification of printing from Reader Mode (desktop), and the option for accessibility settings to respect the system's set font size when displaying web pages (Android). This is also the last version to support Android Ice Cream Sandwich.[307][308]","Firefox 56 was released on September 28, 2017 for both desktop and Android. Among the many additions are: a new layout for the "Preferences" page, the launch of Firefox Screenshots, support for address form autofill, hardware acceleration for AES-GCM, update of the Safe Browsing protocol to version 4, improved security or verifying update downloads (desktop), improvement of support for WebExtensions, and the end of support for Adobe Flash (Android). Starting with this version, Android support is exclusively for Android Jelly Bean and above.[309][310]","Another change was the introduction of the mozlz4 format, a proprietary variant of the lz4 compression format (.mozlz4 and .jsonlz4 file extensions instead of .json.lz4 as per unix/linux standard). Session data is stored in the lz4 format instead of plain text. Firefox 56 cannot recognize the legacy plain text session files, only the lz4-encoded ones.","Firefox 57 was released on November 14, 2017 for desktop and Android with the name Firefox Quantum.[311] ZDNet dubbed it a "comeback" following years of falling market share against Google Chrome.[312][313] The release included a new interface design, codenamed "Photon", and a new rendering engine almost twice as fast as the previous one used.[311][312][314] One of the largest visual changes in Photon was the removal of the search box from the address bar. Firefox 57 no longer supports legacy add-ons using XUL technologies.[315][316][317] That same day, Mozilla announced that Google would be the default search engine in the US and Canada, a departure from Yahoo, which had been the default search engine in the US and Canada since 2014.[318]","Firefox 58 was released on January 23, 2018 for desktop and Android. Among the additions were: support for credit card autofill, the drop of support for user profiles in previous versions of Firefox, a warning to alert users and site owners of planned security changes to sites affected by the gradual distrust plan for the Symantec certificate authority (desktop), full screen bookmark management with folder support, support for FLAC (Free Lossless Audio Codec) playback, the ability to change the status bar color in themes, and removal of the Firefox Search widget from the home screen (Android).[319][320]","Firefox 59 was released on March 13, 2018 for desktop and Android.

Firefox now displays a "This connection is not secure" message when users click into the username and password fields on pages that don't use HTTPS.\nImplemented the Strict Secure Cookies specification which forbids insecure HTTP sites from setting cookies with the "secure" attribute. In some cases, this will prevent an insecure site from setting a cookie with the same name as an existing "secure" cookie from the same base domain.\nEnhanced Sync to allow users to send and open tabs from one device to another.\nImproved text input for third-party keyboard layouts on Windows.
