When I did that, the window opened, but I could not resize it. I tried to find a solution to this online, and the only thing I could find that did anything at all was to select the minimized tab, then press Alt-Tab, and then a little window gives me the option to maximize. I finally clicked on the Firefox icon again, displayed as I hover over the tab in the taskbar, and another Firefox window opened, normally. I tried opening it from the Task Manager, but that didn't work either. When I hover over the tab in the taskbar, it displays a tiny version of the wedge-sized window, but clicking on it does not open it.
It first opened for a moment, long enough to see that it was sized to just a wedge, but then immediately disappeared again.
Today I started up Firefox from the taskbar icon as I always do, and it opened in the taskbar, but doesn't open as a window. After waiting some time, I finally shut down the computer. But this time it was stuck at a very large size, without any movement at all. Usually under Memory in the Processes tab, the number keeps changing, either down, slowly, as it's closing down, or up as it's opening. I saw absolutely no movement under Processes.
No window actually opened, so I went to Task Manager, but couldn't open it from there either. Last night after I closed Firefox, I accidentally clicked on the taskbar icon again, apparently before Firefox was completely shut down.
