New Alpha Release: Tor Browser 12.5a4 (Android, Windows, macOS, Linux)

Tor Browser 12.5a4 is now available from the Tor Browser download page and also from our distribution directory.

This release updates Firefox 102.9.0esr, including bug fixes, stability improvements and important security updates. We also backported the Android-specific security updates from Firefox 111.

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

• NoScript 11.4.20

Tor Browser 12.5a4 also adds support the Finnish language on all platforms. We would like to thank volunteer olavinto for making this possible!
