Every time I click on Firefox to open a window, the taskbar icon and task manager say that it is open, but no window appears on my screen. If I hover over the icon on the taskbar, I can see the window, and even navigate to frequent pages by right clicking, but I can't SEE any Firefox window open.

Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/
  • Linux: *~/.mozilla/firefox/
  • Windows: %AppData%\Mozilla\Firefox\
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\

Locate the xulstore.json file. Then rename or delete it. Restart Firefox.
