Google has not only become dominant because their product is good.
First and foremost, they leveraged their market power through android and their search engine to get people to use chrome.
As another said -- chrome was dominant before Android was a player.
Firefox blew a hole in the IE wall. Then chrome came along and was more acid compliant, leaner (Ux/ui), faster, and it's approach of per-tab processes was superior to a lock-up prone Firefox, or IE.
The other biggest factor IMO Chrome greatly focusing on developer tools --> eventually stealing away firebug dev, and in turn taking the throne as the developer browser of choice.
Chrome was already very popular by the time it became any good (compared to Firefox).
But even sooner than they investing in dev-tools, they made a killing from tab isolation right at a time when Firefox had most of its stability problems.
