Since the last 1-2 months, the latest Firefox browser updates have had this negative effect, that each time when I open the browser in full window, it hides the WIndows 10 toolbar. Normally toolbar comes back visible when I move the cursor to the area, but not now. I need to either click Win+T or to minimize the browser window and then to make it bigger again (full size). That's not the normal solution. Normal shouldn't hide the toolbar at all. This doesn't happen with other softwares, and my toolbar settings in Win10 are like they should be. If this is a known Firefox bug, is there any change that it could be fixed for the next update? Or can I do something by self to fix it? Thanks!
