New

• The Copy Without Site Tracking option can now remove parameters from nested URLs. It also includes expanded support for blocking over 300 tracking parameters from copied links, including those from major shopping websites. Keep those trackers away when sharing links!

  

• Firefox now supports Content-encoding: zstd (zstandard compression). This is an alternative to broti and gzip compression for web content, and can provide higher compression levels for the same CPU used, or conversely lower server CPU use to get the same compression. This is heavily used on sites such as Facebook.

• Catalan is now available in Firefox Translations.

• Enabled AV1 hardware decode acceleration on macOS for M3 Macs.

• Telemetry was added to create an aggregate count of searches by category to broadly inform search feature development. These categories are based on 20 high-level content types, such as "sports,” "business," and "travel". This data will not be associated with specific users and will be collected using OHTTP to remove IP addresses as potentially identifying metadata. No profiling will be performed, and no data will be shared with third parties. (read more)

Fixed

Changed

• The URL Paste Suggestion feature added in Fx125 was temporarily disabled while the team investigates a potential performance issue. The feature will be re-enabled in a future release once the performance issue is addressed.
