I've been an avid hater of Firefox for years now. Every single system I ever used it on had a problem with memory leaks and slowdowns. Did I use addons? Of course I did, that is WHY I used it, because it had some cool addons.
For quite some time now I've been using Chrome with Speed Dial 2, Adblock Plus, Roboform, and Photo Zoom for Facebook.
Is it faster than IE10 ? Dunno, but you can bet your ass it is faster and much more reliable than firefox ever was on it's best days.
