> Why is it Firefox's problem if Apple didn't bother to go to the trouble of making non-Retina applications readable on a Retina display?
I'm not sure what they could have done beyond making sure Cocoa's text-rendering routines produce the right "retina" output. Which they do. Firefox (and Chrome) do their own text rendering and rasterizing, as far as OSX can see it they give it a big image to display. Not much OSX can do with that.
