Mozilla Firefox 133 Released with Bounce Tracking Protection and Tab Overview Improvements
Mozilla Firefox 133.0 is now available for download. The latest browser update introduces a new privacy feature called “Bounce Tracking Protection” that protects users from hidden redirects and data collection while browsing websites. Additionally, the tab overview menu has received several improvements.
New Features in Firefox 133.0:
Firefox introduces a new anti-tracking feature called “Bounce Tracking Protection,” available in the “Strict” mode of Enhanced Tracking Protection. This feature detects bounce trackers based on their redirect behavior and periodically clears their cookies and site data to prevent tracking.
Users can now access tabs from other devices through a sidebar that can be opened via the tab overview menu.
GPU-accelerated Canvas2D is now enabled by default on Windows, improving performance.
Other Changes and Fixes:
The Firefox Labs feature “Picture-in-Picture: Auto-Open on Tab Switch” now works more reliably across a broader range of websites, automatically opening relevant videos while ignoring others.
Cookie “expire” attribute values are now adjusted by adding the difference between server and local time when server time is available. Cookies that haven’t expired according to server time are considered valid even if the current time is set to a future date.
Developer-Related Changes:
- Firefox now supports the keepalive option in the Fetch API, allowing developers to make HTTP requests that continue running even after page unload, such as during navigation or closure.
- The Permissions API is now supported in Worker Context.
- Firefox now dispatches beforetoggle events before dialog opens and toggle events after dialog closes, matching popup behavior.
- New methods for converting to Base64 and hexadecimal encoding are available on UInt8Array, implementing the Stage 3 TC39 proposal.
- Support for image decoding has been added as part of the WebCodecs API, enabling image decoding from both main thread and worker threads.
