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.
==================================
Available via the internal updater: Help / About Firefox
If you use the Enterprise policy DisableAppUpdate, does that disable automatic updates for all apps, or only FF?
On the Options>Privacy & Security screen, under Cookies and Site Data, the option "Accept cookies and site data" is selected. But why is "Keep Until" option grayed out? The box says "Firefox is closed" but can't be changed. Is that the only option available and it's enabled by default even though the the entire line is grayed out?
There's no "Save Changes" on any of the Options screens that I can see. Does that mean they're saved automatically each time a change is made?
