Always had Firefox as my default, even when it was stuck on large, slow releases and was lagging a bit behind Chrome as far as features and speed. My reasons are pretty trivial, and I'll readily admit Chrome can be better to work with in certain dev cases, but I like being able to customize the UI. (I think the back/forward buttons belong to the right of the address bar where they're easier to reach with a mouse and I like having an RSS button, dang it.)
