After a unknown crash of Firefox, I restarted Firefox. The button appeared in the tasbar, but the window was never to be found. Clicking the button didn't help. I used the windows taskmanager to maximize the window, which worked OK, but......... When clicking the "size down" button (top right middle button), the window again disappeared and could not be resurrected again in a normal way.

So at the moment I am stuck with a maximaized window, and I can't resize and move it anymore....

Sincerly hope you have a solution....

Thanks a lot for your info. I have sort of solved the problem in a different way. I am now using "Pale Moon" and since then I haven't seen the problem again. I will download the suggested file, just in case Pale Moon shows the same problem. Best regards, Lody J. Claessen

  • Use Restore or Maximize in the right-click context menu of the Taskbar icon to set focus to the Firefox application if you do not see the Firefox window.
  • Open the system menu of that Firefox window via Alt+Space and see if you can move and resize that window (use the keyboard cursor keys).

If that works then first close all other open Firefox windows and then close Firefox via "File > Exit/Quit" to save that setting.

If the above didn't help then see:
