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.)

Sorry, I listed this as compatible with Android by mistake, as it is really meant for Windows tablets, where you can easily enter full screen but it's much harder to exit. Android compatibility seems to be gone now, but the settings are less than intuitive.
