hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

If you close Firefox while not in full screen mode then Firefox should store this choice as persistent data in the localstore.rdf file.

You can check for problems caused by a corrupted localstore.rdf file.
