95.0 Firefox Release

December 7, 2021

Version 95.0, first offered to Release channel users on December 7, 2021

New

  • RLBox — a new technology that hardens Firefox against potential security vulnerabilities in third-party libraries — is now enabled on all platforms.

  • Good news! You can now download Firefox from the Microsoft Store on Windows 10 and Windows 11 platforms.

  • We’ve reduced CPU usage on macOS in Firefox and WindowServer during event processing.

  • We’ve also reduced the power usage of software decoded video on macOS, especially in fullscreen. This includes streaming sites such as Netflix and Amazon Prime Video.

  • You can now move the Picture-in-Picture toggle button to the opposite side of the video. Simply look for the new context menu option Move Picture-in-Picture Toggle to Left (Right) Side.

  • To better protect Firefox users against side-channel attacks such as Spectre, Site Isolation is now enabled for all Firefox 95 users.

Fixed

  • After starting Firefox, users of the JAWS screen reader and ZoomText magnifier will no longer need to switch applications in order to access Firefox.

  • You’ll find the state of controls using the ARIA switch role is now correctly reported by Mac OS VoiceOver.

  • You’ll see a faster content process startup on macOS.

  • We’ve also made memory allocator improvements.

  • And we’ve improved page load performance by speculatively compiling JavaScript ahead of time.

  • Various security fixes

Changed

  • We’ve added a User Agent override for Slack.com, which allows Firefox users to use more Call features and have access to Huddles.

Enterprise

Unresolved

  • On macOS command-clicking links in Gmail still does not open a new tab. Workaround: you can click links in Gmail without pressing command, which will still open a new tab.
