Ian Laurie:
Regular Firefox became briefly non-functional on Fedora Rawhide due to the following (now resolved) bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1891234
The issue was that all tabs immediately crashed making the browser unusable. I believe Tor is now suffering from the same issue.
This is a known bug in Firefox's current ESR which Tor Browser is based on. We have a ticket[1] for it in our bug tracker, too.
That said, we plan to pick the Firefox fix up with the next release. That one is currently planned for 12/15[2].
