I just find it to be far more customizable.
IE
Firefox
Something else
Firefox, I've been using it since it was still called Phoenix
I'm glad to see the majority uses Firefox or other browsers, I'm sure the result would've been different a few years ago. IE is a pain for web developers, but the situation is improving since IE7.
Firefox, but occasionally I find it starts eating up my RAM. Then I use Opera for a while and go back to Firefox later.
I play and work on an online game (check the sig guys for the link if ya wanna try it) Basically because of modern standards of security ect ect it's hard to configure the downloadable image pack (whilst unnecessary, it speeds the game up some) therefore I have to be able to tweak my browser settings, thankfully Fire Fox have an addon called ChromEdit Plus which even on Vista makes tweaking the necessary file a doddle. Therefore I use FF2 still I haven't gone to the beta because if I do I've heard the compatability runs out with the game image pack. Though whenever I try uploading photos to my facebook/myspace/livejournal the browser suffers a catastrophic crash so for those I tend to go on IE7 and use that.
I use Opera. Its super sophisticated.

You hold my heart in your manly hands I wanna feel the throb of your handsome gland. I wanna hold you tight like a newborn kitten, against my flesh like a cashmere mitten. Tickly tick, I'm makin' skin bump heaven and all the way down it's lookin' cleanly shaven. Prickety pricks, it's stubble on stubble I better slow down or I'm in real trouble. Want you, touch you, feel you, taste you! Knick knack whacky whack 'till I see the man stew. spin you around let me see that hole! I'm a tunnelin' in a like a short hair mole. Once I'm inside I'm gonna leave a trace, half in there and half on that face! One finger, two finger, there fingers gone! Mano a mano I love you John!
It's great for some people. /pointlessly over-defensive
Unfortunetly I use I.E but I prefer Firefox all the way
Firefox. My computer has a lovely habit of closing the internet browser that is open regularly. Firefox allows me to restore what I was doing. It does it so often that if I used IE, I think I'd be pulling my hair out due to frustration.
