I was unable to reproduce the issue by using Firefox 85.0a1 (2020-11-30) after and before updating it, under macOS 10.15.7.
It seems that the reporter says the fix is working (see Comment 16 and Comment 17), so I will remove the qa+ flag based on that. If further investigation is needed, please don't hesitate and ni me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1914147 Title: [upstream] Firefox 85 hangs at startup To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1914147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
