New Release: Tor Browser 14.0
Tor Browser 14.0 is now available from the Tor Browser download page and our distribution directory. This is our first stable release based on Firefox ESR 128, incorporating a year's worth of changes shipped upstream in Firefox. As part of this process we've also completed our annual ESR transition audit, where we reviewed and addressed over 200 Bugzilla issues for changes in Firefox that may negatively affect the privacy and security of Tor Browser users. Our final reports from this audit are now available in the tor-browser-spec repository on our Gitlab instance.
Firefox's design also continues to evolve, and the ESR transition is our opportunity to update Tor Browser to reflect the most recent patterns and styles used in Firefox. For example, eagle-eyed Tor Browser users will notice updates to Tor Browser's typography that we've inherited from Firefox, including heavier headings and changes to line heights intended to improve font compatibility and accessibility.
In addition to the ESR, we overcame many other technical challenges that you can read more about in Morgan's series of blog posts chronicling the team's progress with Tor Browser Alpha, including: unifying Tor Browser for Android's codebase into a monorepo, addressing reproducibility issues in our Android APK generation, reducing Android's APK size for x86 and x86_64 platforms, and changes to how we spoof Tor Browser's user agent, to name a few. This release also includes a series of improvements to the usability and compatibility of our fingerprinting protections without compromising their effectiveness, allowing us to enable useful features like picture-in-picture, screenshots and more.
