Thank you for checking that!

If you still have the profile where it doesn't work, and are willing to do some detective work to figure out what it is that doesn't make it work (e.g. extensions or prefs.js or something else), that would be awesome. You're hardly the only Firefox user with a somewhat old profile, and it's possible that there's something specific going wrong that we should be handling better on our end...
