I like FF as much as the next person and have been using it as my daily driver for a while now, but FF doesn't hold a candle to the responsiveness or snappiness of Chrome. It's especially noticeable on content or media rich sites where FF crawls down to a halt. The general browsing experience is nowhere near as good or refined as Chrome's, but when there's literally no better option you kinda just have to suffer through a sub-par browser.
