New Release: Tor Browser 13.5.22

Tor Browser 13.5.22 is now available from the Tor Browser download page and also from our distribution directory.

This version includes important security updates to Firefox.

Important: this release is part of the legacy channel, meant to extend the support for Windows 7/8/8.1 and macOS 10.12-10.14. If your OS is not one of these, you should download the latest stable from the 14.5 series instead. Further updates to this 13.5.x legacy channel are not guaranteed: please upgrade to 14.5.x as soon as possible.
