New release: Tor Browser 13.0

This is our first stable release based on Firefox ESR 115, incorporating a year’s worth of changes shipped upstream. As part of this process we’ve also completed our annual ESR transition audit, where we review Firefox’s changelog for issues that may negatively affect the privacy and security of Tor Browser users and disable any problematic patches where necessary. Our final reports from this audit are now available in the tor-browser-spec repository on our Gitlab instance.

Particularly notable are the accessibility improvements we’ve gained as a result of the transition to Firefox ESR 115. While eagle-eyed users may notice small visual changes to the user interface (for example, internal links are now underlined), Tor Browser 13.0 is our first release to inherit the redesigned accessibility engine introduced by Mozilla in Firefox 113. This change promises to improve performance significantly for people who use screen readers and other assistive technology.

New Release: Tor Browser 13.0.8 (Desktop)

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.
