Tor Browser 11.5a9 still says it is up to date.

Hi @rngrh344e, have you tried manually checking for updates via “Tor Browser > About Tor Browser”? If so, did you remember to connect to Tor first?

Firefox (and as a result Tor Browser too) will return a result of “Tor Browser/Firefox is up to date” when it can’t actually reach the update server – as technically speaking, no update has been found.


i always update manually. i tried to update several times using new idendity and restarted TBB11.5a9.
the new version is from May 20, 2022. the blog anouncement was added yesterday but
there is still no update available.

I’m having the same issue on Linux.

Running 11.5a9 but it shows no update available when I go to About Tor Browser.


I have filed tor-browser#41005. Thanks for reporting!
