Hide Firefox's toolbar in full screen Mac OS

I cannot get Firefox to go completely into full screen on Mac OS Catalina. When going full screen it will hide the Mac system menu bar at the top, but it will not hide the Firefox address bar. I've researched a bit and found some suggestions about settings in about:config pertaining to full screen access, and I've exhausted all of those suggestions. Is this a known issue on Mac with Firefox?

See this thread about using code in userChrome.css.

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.

Thank You! That did the trick, plus opened the door to a whole bunch of style customization that I can do to Firefox!
