Outlook 2007 -- doesn't recognize Firefox

[JTKirk]

Hi! I'm using Outlook 2007 on Vista OS. My default browser is Firefox 2.0.
Whenever I click a link in Outlook I get an error message saying that FF
isn't recognized. Why? How can I fix this behavior? Thanks!!

What if I'm using Vista? Those instructions appear to be for XP users?
Thanks!
