New Alpha Release: Tor Browser 12.5a2 (Android, Windows, macOS, Linux)

by richard | January 25, 2023

Tor Browser 12.5a2 is now available from the Tor Browser download page and also from our distribution directory.

This release updates Firefox on Android, Windows, macOS, and Linux to 102.7.0esr. It includes important security updates to Firefox and GeckoView. There were no Android-specific security updates to backport from the Firefox 109 release.

We use this opportunity to update various other components of Tor Browser as well:

  • tor
  • NoScript 11.4.14
  • go 1.19.5

We would like to thank user ryotak for identifying a script blocking bypass on local file:// resources. We would also like to thank user cypherpunks1 for their help with tor-browser#40717 and tor-browser#41578 (among others). If you would like to contribute patches or help diagnose issues, please join us on our gitlab instance!
