firefox blocks the windows task bar

[rooroo]

Hi,
I have a persistent issue with firefox on win 10 (updated). When firefox (v135) is maximised there is no windows task bar when the mouse cursor is moved to the bottom of the screen.
its only firefox, no other application does this. the other nag is this issue is random when other application are running in the back ground. they might be media player classic, explorer, thunder bird typical everyday programs. often the only way to fix it is minimize firefox, move task bar to the top of the screen then back to the bottom again, it lasts for a few hours before the issue come back again. most annoying, any ideas?

Have this problem myself (Win10), starting several months ago and like most user find it annoying.  This problem goes back almost a decade.  There seems to be several suggested causes.

1 NVIDIA GeForce drivers.  Not me, not a gamer and use onboard graphics

2 Problems related to resolving screen resolution.  I would assume this would be a relatively simple fix certainly after a decade. Default FF settings should not be set to be always on top.

This has been a persistent problem and I suspect that it is some form of inadvertent or otherwise incompatibility that shifts with the overlap between FF and M$ Win updates.

However I have observed that my problem only occurs on normal FF.  If I open a Private FF instance the problem does not seem to occur unless it is intermittent

Small update that is a simple two step process and less torturous than dropping out of full screen and selecting other application and the maximising on return to FF.

In the  Bronze age of Windows many techniques based on the Stone age tools of DOS where implemented and still work; sort of.  Alt-Tab would step you round open windows.  Still works but you are presented with a collage of open windows that you can select from.
