# Delete "XUL.mfl" (the name may differ slightly, e.g. "xul.mfasl") from your [[profile folder]]. This file will be regenerated on next startup. Try running Firefox now.

# Delete the "Cache" folder. (You will lose your cache.)

File names and program names are different for Mozilla Suite.

If Firefox used to work correctly, but it no longer starts when you try to run it, then this article may help.

Profile In Use

If you receive the "profile is in use" error when trying to launch the application, this means the profile is locked. See the Profile in use article for instructions on fixing this.

Settings Are Gone

  • Make sure you're using the correct profile. Run the Profile Manager and select the default profile.
  • If that wasn't your problem and you have backed up your profile, you should be able to simply copy the backed up files to your new profile. See "What do I do if my profile's corrupted?" for help on doing this.
  • If you are missing themes or extensions, you will have to reinstall them from scratch.

Doesn't Start At All

Perform the standard diagnostic.

From Firefox 1.0.2 Release Notes:

If Firefox does not display a browser window, quit Firefox using Cmd+Q and open ~/Library/Application Support/Firefox/Profiles/<garble>.default/ and remove "localstore.rdf". Restart Firefox. Any toolbar customizations you have made or window placement will be lost
