IE's numbers were falling and Firefox's were climbing, but then Chrome joined the battle. A funny thing happened at that point. Firefox, once the most beloved browser by users 'in the know,' took a backseat to Chrome's rapid rise, and now it's anyone's guess what the next year or so will bring. Let's have a look where things stand.
