I think multiprocess/multi-tab was a big separator for a long time, as well as plugin memory leakage being way worse on Firefox (initially because Chrome had nearly none to speak of). I very reluctantly switched to Chrome. I loved Firefox. I even know today that Firefox likely suits my needs better... but at this point I'm too old and too stuck to change. Chrome doesn't yet make me so angry that I have to switch. Horowitz is right (along with every other entrepreneur) when they say for someone to switch, the next product has to be an order of magnitude better than the currently adopted product. Anything less isn't enough.
