Une nouvelle mouture du navigateur Firefox est arrivé. Au programme, améliorations de performances pour les utilisateurs de macOS et Windows (grâce à une nouvelle méthode de compilation). Les webextensions fonctionneront enfin dans un processus à part pour les utilisateurs de Linux et le thème par défaut de Firefox suivra automatiquement le mode choisi (clair au sombre) défini par l'utilisateur dans les paramètres de Windows 10.
Voici la liste complète des modifications par rapport à la version précédente :
Fixed
- Games using WebGL (created in Unity) get stucks after very short time of gameplay (bug 1502748)
- Slow page loading for some users with specific proxy configurations (bug 1495024)
- Disable HTTP response throttling by default for causing bugs with videos in background tabs (bug 1503354)
- Opening magnet links no longer works (bug 1498934)
- Crash fixes (bug 1498510, bug 1503424)
Fixed
- Snippets are not loaded due to missing element (bug 1503047)
- Print preview always shows 30% scale when it is actually Shrink To Fit (bug 1501952)
- Dialog displayed when closing multiple windows shows unreplaced %1$S placeholder in Japanese and potentially other locales (bug 1500823)
New
- Performance and visual improvements for Windows users
- Moved the build infrastructure of Firefox on Windows to the Clang toolchain, bringing important performance gains
- Firefox theme now matches the Windows 10 OS Dark and Light modes
- Performance improvements for macOS users
- Improved reactivity
- Faster tab switching
- WebGL power preferences allow non-performance-critical applications and applets to request the low-power GPU instead of the high-power GPU in multi-GPU systems
- Added content blocking, a collection of Firefox settings that offer users greater control over technology that can track them around the web. In 63, users can opt to block third-party tracking cookies or block all trackers and create exceptions for trusted sites that don’t work correctly with content blocking enabled.
- WebExtensions now run in their own process on Linux
- Firefox now warns about having multiple windows and tabs open when quitting from the main menu
- Firefox now recognizes the operating system accessibility setting for reducing animation
- Added search shortcuts for Top Sites: Amazon and Google appear as Top Sites tiles on the Firefox Home (New Tab) page. When selected these tiles will change focus to the address bar to initiate a search. Currently in US only.
Fixed
- Resolved an issue that prevented the address bar from autofilling bookmarked URLs in certain cases
Changed
- In the Library, the Open in Sidebar feature for individual bookmarks was removed
- The option to Never check for updates was removed from about:preferences. You can use the DisableAppUpdate enterprise policy as a substitute.
- The Ctrl+Tab shortcut now displays thumbnail previews of your tabs and cycles through tabs in recently used order. This new default behavior is activated only in new profiles and can be changed in preferences.
Developer
- Refreshed visual style of Developer Tools menus to improve navigation and consistency
- The Dev Tools accessibility inspector is now enabled by default. This tool surfaces information exposed to assistive technologies on the current page, allowing you to check what’s missing or otherwise needs attention.
- Added support for Web Components custom elements and shadow DOM
- The inspector now ships with a Font Editor that allows you to control non-variable as well as variable fonts
