I like Firefox best - basically because of NoScript & Adblock Plus, and I find it MUCH easier to configure the browser settings to my preferences. I also appreciate the fact that Mozilla generally releases a patch with a day or two of a vulnerability being discovered. I have IE8 loaded as well, but I never use it. Well, rarely anyway. (Though I think most of my applications use it's engine to update even though I have FF set as my default browser). I also have Safari, which I have never even opened. Safari (along with QuickTime and iTunes) was downloaded automatically (either that or my father just clicked next next next in the set up wizard without reading what he was agreeing to) with the Vista-compatible drivers for my Canon digital camera. Ugh. I seem to have QuickTime as a default application for many things in Firefox, so I haven't un-installed the Bonjour for Windows (or whatever it's called - the Apple stuff).
