Last updated: January 12, 2022

Mozilla Firefox 96.0 was released today. The new release focuses on performance and security improvements.

Firefox 96.0 significantly reduced the main-thread load, improved noise suppression and automatic gain control for better overall experience.

It now enforces the Cookie Policy: Same-Site=lax by default which helps defend against Cross-Site Request Forgery (CSRF) attacks.

The release also fixed some issues, including video quality degradation issues on certain sites, issue where WebRTC downgrades screen sharing resolution, and video intermittently drops SSRC. As well, there are various security fixes.

And for developers, Firefox 96 adds WebP image encoder support for canvas.

      Connection issues have been reported for the latest version. The reason is unclear, it appears to be related to the HTTP3 implementation. Anyway, if someone has this kind of problem, here’s the fix:

      – In about:config search for network.http.http3.enabled
      – Set the preference to FALSE
      – Restart Firefox
