I used FF and Chrome in parallel for a while until about a year ago, when I realized that I had almost completely switched to Chrome.
By this time, I had cut down my FF install to nearly the bare bones minimum. FF's strongest selling point, it's extensibility, was what was causing me most of my headaches.
Don't get me wrong. Chrome has a certain Apple attitude about things - Our Way is the Right Way. I've filed a lot of issue reports, usually over a lost feature in an update, only to be told that, no, that's the way it's supposed to be. I just got one back yesterday. Can't reorder the home/most visited screen anymore. I can delete any thumbnail to have the eight (and only eight) that I want on screen, so this is in fact NOT technically a "most visited" screen, but I can't have them in the order that I want them? I mind this much less than bizarre behavior in FF.
