Firefox disappears to the right

Firefox keeps disappearing to the right when the icon is clicked. Placing the mouse over the icon on the taskbar shows the firefox window, but it will not open.

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

If you are a patient person, you may be able to move a missing window on-screen using this method (because you have a strong suspicion that it is off screen to the right):

  • activate the Firefox window using the Taskbar icon
  • press Alt+Spacebar to call up the window control menu
  • select Move
  • hold down the Left arrow key on the keyboard until the window reaches a suitable position and press Enter to terminate the move
