Help me get back to Firefox. It has disappeared from my screen and I can't get to it for email, etc. I am on Safari now to get to you.

What's your computer system and Firefox version?

What do you mean by disappeared? Is the browser opening/not opening? Check the computers Task Manager.

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

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 \Mozilla\Firefox\Profiles\

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