Title bar buttons don't work when pressing Alt
I have a problem with Firefox. I think this is a bug. I have tested it in Firefox 85, 86 and 87.
When I press Alt, the complete title bar with the menus File, Edit, View, ... appears. Afterwards, when I click Minimize, Maximize, Close, New Tab or List All Tabs, the title bar is minimized again but nothing else happens. Those buttons just don't work.
Is there a way to fix this problem? Is it likely to be fixed sooner than three months/six months/years? Please tell me how I can add anymore useful information. Thanks for your support!
