I hve uninstalled and reinstalled firefox. The icon is in the toolbar. It shows that the screen is open but I can not open it on my monitor. It disappears to the top right corner. I have been using firefox for years and not it doesnt work.

Try to start Firefox in Safe Mode:

  • On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
  • On Mac, hold down the Options key while starting Firefox
  • Help > Restart with Add-ons Disabled

Try to 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:
