XULRunner profile error

I seem to keep getting a popup every few hours regarding XULRunner complaining about "This profile was last used with a newer version of this application. Please create a new profile." This will occur every so often, even when Firefox is not open.

I have already attempted to:

  • Reboot
  • Clear cache
  • Uninstall extensions
  • Uninstall/reinstall Firefox
  • Downgrade Firefox
  • Make a new profile and switch to it
  • Delete all previous existing profiles

I think I've run out of things to do, anyone got a silver bullet for this thing? I was unable to find anything conclusive with Google, so I figured I'd ask here.
