New Alpha Release: Tor Browser 12.5a5 (Android, Windows, macOS, Linux)

by richard | April 21, 2023

Tor Browser 12.5a5 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 112.

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

  • NoScript 11.4.21

Build-Signing Infrastructure Updates

We are in the process of updating our build signing infrastructure, and unfortunately are unable to ship code-signed 12.5a5 installers for Windows systems currently. Therefore we will not be providing full Window installers for this release. However, automatic build-to-build upgrades should continue to work as expected. Everything should be back to normal for the 12.5a6 release next month!
