Whenever I open fire fox it automatically opens in fullscreen. Hitting F11 does nothing. I open it in safe mode and I see the address and search bar and everything but I am unable to click on them and honestly it doesn't even look right when I open it up in safe. I provided pictures. I have been all over the settings and looked into multiple forums that all say the same things and tells you how to get out of fullscreen mode but not anything on how to stop it from happening automatically on open. I have uninstalled and re-installed as well.

Anyone have any insight?
