Whtie bar at top of videos

The other day I started seeing a white bar at the top of full screen videos. Not just YouTube but any site that uses a video. It's very annoying. I've tried disabling ad blocking, various features in Firefox, my AV, plugins, and anything else I can find to no avail. Using the Developer tools doesn't see anything where the white bar is. It's driving me nuts! What would be causing this white bar and how do I remove it?

Figured it out. A recent Firefox update caused some code in my userChrome file to show an empty area. I was resizing the Browser window to have Tabs below the Bookmarks toolbar. Resizing the the container for all the toolbars solved it.
