New Alpha Release: Tor Browser 12.5a6 (Android, Windows, macOS, Linux)

by richard | May 24, 2023

Tor Browser 12.5a6 is now available from the Tor Browser download page and also from our distribution directory.

This release updates Firefox 102.11.0esr, including bug fixes, stability improvements and important security updates. There were no Android-specific security updates to backport from the Firefox 113 release.

Build-Signing Infrastructure Updates

We are in the process of updating our build signing infrastructure, and unfortunately are unable to ship code-signed 12.5a6 installers for Windows systems currently. Therefore we will not be providing full Window installers for this release. However, automatic build-to-build upgrades from 12.5a4 and 12.5a5 should continue to work as expected.
