New Release: Tor Browser 13.5.21

Tor Browser 13.5.21 is now available from the Tor Browser download page and also from our distribution directory.

This version includes important security updates to Firefox.

Legacy Channel End of Life!

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.

Important: Tor Browser 13.5.21 is based on the last 115.x ESR version officially announced by Mozilla: therefore we cannot guarantee further updates to this 13.5.x legacy channel. Please upgrade to 14.5.x as soon as possible.
