Same as this problem: [[https://support.mozilla.org/en-US/questions/1320568|taskbar hidden]] My taskbar is set to auto hide and I want to keep it that way. Other chromium based browsers does not have this problem. When I hover my mouse to the bottom of the screen, the Windows 10 Taskbar won't appear. Only when I press the windows key, then it appears. This has been happening on both of my computer for a long time now and it's very frustrating. I am sure I am not in full screen mode. Restarting the browser, or windows explorer or the PC doesn't work. Reinstalling FF also does not work. Finally trying to switch completely to FF but this is keeping me from doing it. Any help would be appreciated.
