If the browser is running, but not showing on the screen, it could be the window is open outside where you can see it.

Let's try the easy way first.

Do you have the Firefox icon on your quick launch? Right-click on it and select Open New Window. Sometimes this works.

Close the first window. Wait a few moments, then close the browser by Menu > File > Exit.

If the above does not work, You may have corrupt xulstore.json file.

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

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


Search for the above file. Then rename or delete it. Restart Firefox.
