For Windows version 10.0.19045 Build 19045 If using Firefox Version 113.0.1 (64-bit) in Windows 10 and in the following state:
Firefox is open and window is maximized. Firefox Full Screen is toggled OFF. Windows taskbar setting "Automatically hide the taskbar in desktop mode" is toggled ON.
Then the Windows taskbar will not display when the cursor is place at the bottom of the monitor screen. If the Windows taskbar setting "Automatically hide the taskbar in desktop mode" is toggled OFF. Then the Windows taskbar will also not display. Changing the ON/OFF state of any other Windows taskbar display setting in any combination does not fix the failure.
