Windows task bar no longer auto hides when I fullscreen a flash video.
Like the question reads, my task bar is no longer auto hiding when I full screen flash videos in firefox. Other than the obvious issue of it just being unsightly and annoying, It also causes a few other problems. One being that the computer no longer recognizes that a fullscreen video is playing so it goes to screen saver, and goes to sleep at its normally timed intervals.

If you're using higher DPI settings, please check "Disable display scaling on high DPI settings" on 'firefox.exe' (=> right-click - Properties - Compatibility tab). Also see https://support.mozilla.com/en-US/questions/880714
