- Behavior is exactly as in https://bugzilla.mozilla.org/show_bug.cgi?id=1689809. When the bug occurred I could only see the frame.
- I have managed working around the bug. This seems definitely to be caused by some race. Disabling all the extensions and re-enabling them one by one I managed "fixing" the problem without having to reset my profile.
