New Alpha Release: Tor Browser 11.5a1 (Windows, macOS, Linux)

by boklm | December 14, 2021

Tor Browser 11.5a1 is now available from the Tor Browser download page and also from our distribution directory.

This is the first alpha version in the 11.5 series. This version updates Firefox to 91.4.0esr, which includes important security updates.

We are also fixing some of the known issues that were introduced with Tor Browser 11.0. In particular, this release should fix the crashes a lot of our Windows users have been seeing.

Note: A new PGP subkey was used for signing this release. You may need to refresh your keychain from keys.openpgp.org to get the updated key.

Awesome, thanks for testing it @hajj3!

Confirming that my experience with bug 40721 on twitch.tv is fixed. Not extensively tested, but every single subpage on the site would crash beforehand, and this time it worked on the first try, so I’m pretty sure I don’t need to look further.
