clicking on firefox does not bring up a browser. tried to uninstall but firefox says program is already running. But I have no browser. I just want firefox OFF my computer, I am tired of the slow speed and now the inability to remove the program.

Rebooting the computer should close any program.


Firefox is running, but no visible window? https://support.mozilla.org/en-US/kb/changes-toolbars-and-window-sizes-are-not-saved You may have corrupt xulstore.json or Localstore.rdf 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

Search for the above files. Then rename or delete them. Restart Firefox.
