  • 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.

If that works then close Firefox (File > Exit/Quit) to save that setting.
