Updates 11/26/24 - Firefox

Firefox Version 133.0, first offered to Release channel users on November 26, 2024

• Firefox now has a new anti-tracking feature, Bounce Tracking Protection, which is now available in Enhanced Tracking Protection's "Strict" mode. This feature detects bounce trackers based on their redirect behavior and periodically purges their cookies and site data to block tracking.

• The sidebar to view tabs from other devices can now be opened via the Tab overview menu.

  

• GPU-accelerated Canvas2D is now enabled by default on Windows providing a performance improvement.

Fixed

• Various security fixes.

• The “Picture-in-Picture: auto-open on tab switch” feature from Firefox Labs now behaves more reliably across a wider range of sites, automatically opening relevant videos while ignoring others.

Changed

• When server time is available, the "expire" attribute value is adjusted by adding the difference between the server and local times. If the current time is set in the future, cookies that have not expired according to the server time are considered valid.
