Problem with maximizing Firefox window

[Sylva_P]

In Windows (10 and 11), I look at a Firefox window with several tabs and have the window maximized to the whole screen, and then minimize it or move to another program. When I want to maximize the minimized Firefox window or return back to Firefox by clicking on the icon on the main panel (selecting the proper Firefox tab), the window maximizes to a smaller size than before minimization (I think the term is the restored or normal size). But the restored size should be the maximized one, not the normal one. The problem is evident especially when I am using one tab before minimization and then return to another tab with maximization (but sometimes the problem is with the same tab, too).
