Tor Browser 11 removes support for V2 Onion URL and adds new user interface


The Tor Project released Tor Browser 11.0 with a new user interface design and the removal of support for onion V2 services.

Tor Browser is a customized version of Firefox ESR that allows users to browse the web anonymously and access special .onion domains that can only be accessed through Tor.

You can download Tor Browser from the Tor Project site, and if you are an existing user, you can upgrade to the latest version by going to the Tor menu > To help > About Tor Browser.

However, the most significant change is the deprecation of onion V2 services, which means TOR URLs using 16 character short hostname domains are no longer supported.

When attempting to open a V2 Onion service, Tor Browser will show users an “Invalid Onionsite Address” with an error code of 0xF6.

“Last year, we announced that onion v2 services would be deprecated at the end of 2021, and since version 10.5, Tor Browser has been busy warning users who visit onion v2 sites to their next retirement, ”the Tor Project explained in the Tor 11 browser release notes.

“Finally, that day has finally arrived. As of the update to Tor 0.4.6.8 v2, onion services are no longer accessible in the Tor browser, and users will instead receive an “Invalid onion site address” error.

With this change, Tor sites using onion V2 services will no longer be accessible, but admins can upgrade to a V3 onion service by adding the following lines to the torrc to file.
