I'm glad some people care about browser performance, care about creating art and apps that push performance, because without them we won't get to that future where there's a viable, open, free, standards based platform that people can use to challenge the dominance of truly closed source native app platforms.

So yes I am shocked to hear that you don't care. And I'm a bit shocked to see you rant at a person that simply suggested Firefox's JS engine may not be as performant as Chrome's.
