Tor Browser 13.0.8 is now available from the Tor Browser download page and also from our distribution directory.

This is an emergency desktop-only release which fixes a crash in pluggable transports for Windows 7 users. The most recent Go toolchain update seems to have finally broken Windows 7 suport (see golang/go/#57003 for background). We have downgraded our lyrebird, conjure, and webtunnel pluggable transports to the 1.20 series and they should be working once more on older Windows systems. Unfortunately, the snowflake pluggable transport depends on the 1.21 series to work, so it will remain broken on these systems.

We highly encourage Tor Browser users who are still on Windows 7 or 8 to either upgrade their systems to a modern Linux distribution, or at least to a supported version of Windows (10 or higher). Tor Browser will neccessarily have to drop support for Windows 7 and 8 after the ESR 128 transition next year, as Mozilla's minimum Windows operating system requirements is now Windows 10 or newer as of Firefox 116.
