This blogger is a pretty avid Firefox user and it was one of the first applications he/she installed. The problem that he/she ran into was that all the KDE applications were still using Konqueror as their browser.
Ok; at this point I was getting frustrated. So I launched Konqueror itself to see if there was any option that I can change there to unset it as the default browser. Go to Settings->Configure Konqueror. Next go to file associations. This is where it gets a little bit confusing. Look for text in the list of file types and expand that. Once you expand it; chose html. Now you will see that Konqueror is listed before Firefox. So that was the culprit!
