Tab overview (Source – Mozilla)- Improved Tab Management : Users can now open the sidebar to view tabs from other devices directly via the Tab overview menu.
- Performance Boost on Windows : GPU-accelerated Canvas2D is enabled by default, offering better rendering performance.
- Enhanced Picture-in-Picture (PiP) : The “auto-open on tab switch” feature from Firefox Labs now works more reliably across various websites, automatically opening relevant videos while ignoring others.
- Cookie Handling Improvements : When server time is available, the “expire” attribute value is adjusted by accounting for server-local time differences. This ensures cookies remain valid even if the local time is set incorrectly.

- Support for the keepalive option in the Fetch API allows HTTP requests to persist during page navigation or closure.
- The Permissions API is now supported in Worker Context.
- New methods on UInt8Array enable easier conversion to and from Base64 and hexadecimal encodings.
- Added support for image decoding as part of the WebCodecs API, enabling image decoding on both main and worker threads.
