If they focused instead on speed, and somehow managed to keep old plugins compatible, yes.

People moved to Chrome coz it was plainly faster and those who stayed did it for the various plugins they got used to. When new version of FF blows up your workflow might as well go try Chrome. Hell, I'd be using Chrome already if it had sensible vertical tabs implementation... the FF ones after the apocalypse are worse than XUL ones but still better than I've seen on Chrome.
