Updates 12/7/21 - Firefox

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.
