As what title says, please fix it! I believe every firefox user can reproduce.
If you cannot make user experience better, just don't release it!
Firefox user here also. Experiencing same thing.
Went to youtube, paused video, and now can't get focus back to firefox.
Tried clicking outside of video player, but still no response from keyboard (eg: up, home, alt, f5)
Same problems in Firefox safe mode.
Same problem here...except when it isn't crashing. This version should have never been released!
hopefully the developers can get this resolved.
the new protected mode feature has problems with firefox.
