Well, At the risk of talking to myself I did find the answer to my own question. I did indeed need to do more configuration. The properties of each of the entries in the "Application Preference Order" can be edited. Once in the properties, the "execute" tab's "command:" needs to be modified to read: mozilla %u and then Mozilla will work as expected when a link is clicked in kmail. Hope this'll help someone else.
