New Release: Tor Browser 11.0
Tor Browser 11.0 is now available from the Tor Browser download page and our distribution directory. This is the first stable release based on Firefox ESR 91, and includes an important update to Tor 0.4.6.8.
Update: The version of Tor Browser for Windows available on the Tor Browser download page has been temporarily reverted to 10.5.10 while we investigate an issue with NoScript. Please see Bug 40695 for updates.
Tor Browser gets a new look
Earlier this year, Firefox’s user interface underwent a significant redesign aimed at simplifying the browser chrome, streamlining menus and featuring an all-new tab design. Firefox ESR 91 introduces the new design to Tor Browser for the first time.
To ensure it lives up to the new experience, each piece of custom UI in Tor Browser has been modernized to match Firefox’s new look and feel. That includes everything from updating the fundamentals like color, typography and buttons to redrawing each of our icons to match the new thinner icon style.
In addition to the browser chrome itself, the connection screen, circuit display, security levels and onion site errors all received a sprucing-up too – featuring some small but welcome quality of life improvements to each.
Final deprecation of v2 onion services
Last year we announced that v2 onion services would be deprecated in late 2021, and since its 10.5 release Tor Browser has been busy warning users who visit v2 onion sites of their upcoming retirement. At long last, that day has finally come. Since updating to Tor 0.4.6.8 v2 onion services are no longer reachable in Tor Browser, and users will receive an “Invalid Onion Site Address” error instead.
Should you receive this error when attempting to visit a previously working v2 address, there is nothing wrong with your browser – instead, the issue lies with the site itself. If you wish, you can notify the onion site’s administrator about the problem and encourage them to upgrade to a v3 onion service as soon as possible.
It’s easy to tell if you still have any old v2 addresses saved in your bookmarks that are in need of removal or updating too: although both end in .onion, the more secure v3 addresses are 56 characters long compared to v2’s modest 16 character length.

Last week we announced a new discussion and user support platform: the Tor Forum. Starting today, we’re going to be doing things a little bit differently – rather than commenting on the blog posts themselves, we’d like to invite you to create an account and join in the discussion on the forum instead:
If you find a bug or have a suggestion for how we could improve this release, please let us know. Thanks to all of the teams across Tor, and the many volunteers, who contributed to this release.
