I chucked out Internet Explorer and started out on Firefox as my default browser. Frankly, I didnt find much difference between the two, but the tabbed browsing & the spyware protection features tilted the scale towards Firefox. I loved the single click transfer of all my settings, favorites, history and passwords from IE. Oh yeah, there’s the kick of supporting an open source venture. Firefox’s usage is increasing rapidly. It’s already beaten Netscape & Opera…so if you own a site, make sure your site appears fine in this one.
