When Firefox closes by itself (crashes) or becomes unresponsive and I manually close it via Task Manager afterwards when I click on Firefox Desktop icon or Firefox taskbar icon Firefox opens but only at the Taskbar and not full Desktop screen.
See posted image.
The only fix is by deleting the Profile folder in Mozilla AppData hidden folder and replacing it with a restored copy from a System Backup file or a copy of a previous Mozilla Folder with Profiles Folder in it.
Once I replace the current Firefox Profile folder Firefox starts working normally again and starting full screen on my Windows Desktop.
This has been happening the last couple of Firefox versions and with the latest version installed.
Seems to be some sort of conflict with Windows 11 Pro or possibly a Windows security issue.
Thanks in advance
NOTE: I tried pressing Ctrl or Windows key + Arrow Keys to see if possibly it was hidden by Windows. Sometimes if I press Ctrl or Windows Key + and Arrow key the hidden app would show up. But this happens very rarely.
