Bookmarks Toolbar & Graphics Glitches in Latest Version

After upgrading to the latest version (112.0.1) on MacOS 10.15.7, the bookmarks toolbar disappears when I enter fullscreen mode ('Always Show' is selected under Bookmarks Toolbar in the View menu). When I exit fullscreen mode, the toolbar reappears but a large grey bar then appears at the top of the window (see screenshot). I've read answers in the knowledge base that suggest that the toolbar always disappears in fullscreen mode, but I am 100% sure that this behaviour did not exist before the recent upgrade (perhaps this behaviour has been around for a while in Windows?). Either way the grey bar is clearly a bug and feels related to the toolbar behaviour. Has anyone else experienced this?

The blank bar at the top was mentioned in a recent thread about problems using video full screen and browser full screen at the same time. (Please don't try it!)

I don't have a Mac, but for comparison, on Windows, it's normal for all of the toolbars (and the menu bar) to be hidden in full screen, but we can maximize a window without losing anything. Sounds like Mac has a different approach.

Thanks for your reply! I get the blank bar when entering and then exiting full screen, no videos involved at all. Should I report this as a bug to Mozilla?

Yes, I would say that the "Full Screen" you get when clicking the green circle at the top of a Mac window is closer to "Maximise" on Windows than "Full Screen" on Windows. I've been using this fullscreen mode for years with Firefox on MacOS and the bookmarks toolbar has always, always been visible, before this update.

If you have time to file a bug, that would be very useful.
