I have Firefox 25, Chrome 31, and IE 11 on my main home machine, and IE11 is easily my favorite. It's the most stable, uses the least memory, and is the fastest. If that should change in a week or three i will rely more heavily on one of the others, but I use all three and like speed and stability. Firefox is a memory hog to epic proportions, I honestly can't see how anyone who has used both in the last year can prefer FireFox.
But but but , IE is a memory hog!!
