The problem with making "blanket statements" is that you have to know what the hell you're talking about. Mea Culpa. The last iteration of Firefox I looked at bundled a mail client (I think, although it may have been Navigator 7 now that I think hard about it)- now a separate entity named Thunderbird is used for mail and separate from the Firefox browser... Peter is correct in that Firefox is not Cocoa based (Aquafied) and the pages "seem" to browse slower, again, this is subjective. I will try using Firefox again and post back my new impressions as well as the latest Opera.

No matter what, I can say without reservation that Opera, Mozilla, Firefox, Camino and Safari all are viable alternatives to IE if not "better browsers" for OSX. Up to this point, I have been using Camino for most everything exept the most stubborn asp shit sites for which I use Safari with the Debug menu set up to mimic IE 6 for Windows... :-)
