Font Smoothing in Firefox (Mac)

I've been loving the font smoothing CSS property in Webkit based browsers so far but there wasn't any way so far to get that working in Firefox, not till now.

Am sure you are aware of the following property, in case not, have a look at Max Voltar's Post:

body { -webkit-font-smoothing: antialiased; }

To get the same working in Firefox you can use the following:

body { -moz-osx-font-smoothing: grayscale; }

But as it appears, it works on Mac only. No idea if this font smoothing is going to be available for other OS any time soon.
