windows 10 I open firefox in full screen mode, ever other time I start firefox the screen size is too large and the top of the screen show only the bottom half of the internet address line. The tabs and "X" to close the window are off the top of the screen. F11 only make it worst. I can fix it by doing a reset, but the problem keeps coming back, a day or 2 later. My only recourse is to close firefox from the windows 10 task bar - right click and select close. Then reopen firefox and all is good. Next I open firefox screen too big again.
