I can't agree. Firefox is great, but I think its UI drags it down in various ways. It being built the way it is was a boon back when extensions were capable of radically changing the browser's UI, but now it simply puts a (unfortunately low) hard cap on how excellent its UI can be.

Funny enough, Epiphany used to be a more power user oriented browser, and it used to be powered by none other than Gecko. Unfortunately, Mozilla killed embedding in Gecko and that (along with related projects like Camino and K-Meleon) came to a screeching halt and Gecko became hard coupled with Mozilla's UI decisions.
