Firefox 4 on old ppc mac

If you're like me excited about the new Firefox 4 and wants to install it on your old mac (G4 or G3) you're going to see this :

Not a particularly very friendly way to say that your old mac sucks ... and you should buy a new one with an intel processor in it !

But there is a way ... it's called TenFourFox and it's a fork of Mozilla Firefox 4 for the PowerPc platform - and it rocks (except the icon which is a bit cheesy).

Mozilla left us. Apple left us. But they didn't! kudos to them.
