Hi Windows users! While we work with Mozilla on a permanent fix for the tab and addon crashes in Tor Browser 11 (see the 11.0.2 release post for more background), we’ve deployed a temporary fix in our newest alpha release for testing:
If you could download the Alpha and verify whether or not the temporary fix works, I would be super grateful!
Note: Tor Browser Alphas are unstable releases meant only to find bugs and test new features. Please stick to Tor Browser’s stable release for your regular browsing, and do not use Tor Browser Alpha if you are at high risk.
Become an Alpha Tester
You can also sign up to become an alpha tester to get notified by email whenever a new Alpha is available. Alpha testers are encouraged to post any bugs they discover in either Gitlab or the Tor Browser Alpha Feedback category on the forum too.
As a small non-profit the contribution our community Alpha testers make towards helping identify issues with Tor Browser is invaluable 
(Tagging @anta, @ansoufly2, @Portus, @Comms, @LupoIam, @chronoquairium, @Gatsby, @UBO, @g7777 and @hajj3 – let me know either here or in the Alpha thread if this fix works for you!)
