What do you mean by "doesn't work"? You don't see the buttons? Or you see them but they don't do anything? Did you try multiple sites? Is your experience the same for all? On some sites the buttons have little squares instead of the icons, but they still work.

(I tracked down somebody with Quantum on Macbook Pro and works as expected. Anyway, this is meant to be used on tablets or at least things with touch screens, so not sure why you'd want it.)
