Using Firefox 30 under Windows 7, list of applications is completely empty--no file associations of any kind, and I'm unable to add any new ones. I've created a new profile, reset Firefox, done a complete uninstall and reinstall, to no effect. Any suggestions?

Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:

  • Windows/Mac: Go to Help > Restart with add-ons disabled
  • Linux: Run firefox -safe-mode in the Terminal/Konsole

If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.


I'm always suspicious of extra add-ons/toolbars provided during install of Antivirus software. It's pointless!


Did you delete the mimeTypes.rdf file from your Profile Folder? Just makin' sure

Thanks for the suggestion moses. Unfortunately I still have an empty application list when I restarted in safe mode.
