Firefox was working fine up until about an hour ago. In the attached image, you can see the bookmarks toolbar, but everything above it is white. There's no tab. There's no menu (File, Edit, View, etc.). There's no URL bar/search bar, and no little X to close the window when I'm done.

It is not in full screen mode, although if I hit F11 twice the menu, etc. will miraculously appear.

I tried deleting the xulstore.json file as one post here suggested. I tried refreshing Firefox.

I have a Windows 10 computer running Firefox 79.0.

Did I click some weird keystroke combination? How can I make my screen look normal again?

Does the menu bar appear if you press the Alt key or Alt+F to open the file menu ?

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting for changes to take effect.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
