Browser War

I had a discussion the other day with a tech guy about browsers... specifically Mozilla Firefox versus Internet Explorer. Personally, I like Mozilla better than IE and he didn't understand why I liked it so much better! I told him that I liked the tab feature, etc., etc. He told me that you could do all of that in IE, but it wasn't "idiot" proof... I was just wondering what everybody browses in and why they like it.

Thanks!
