News New Release: Tor Browser 13.0.12

[Dark_Duck]

Tor Browser 13.0.12 is now available from the Tor Browser download page and also from our distribution directory.

This version includes important security updates to Firefox.

Removal of automatic .onion site prioritization​

The Tor Project has recently been notified of a potential fingerprinting vulnerability with automatic Onion-Location redirects. In an abundance of caution, we have removed the 'prioritize .onion sites when known' option from Tor Browser. We are looking further into this issue and will provide timely updates as more research and additional recommendations become available.

If you find a bug or have a suggestion for how we could improve this release, please let us know.
