You want this for free or what? I'm not even sure that what you're asking for is legal. It's more than likely not as that logo is protected by copyright I'm sure. Even though their browsers are open source, I don't believe the graphics are. I guess it depends on what you're using it for. If you just want it to make some posters or something for yourself maybe it's fine.
I could be wrong...if I am, maybe someone could post here about it. I did a vectorized logo of the "T-rex with the star behind it" for a splash screen I made a while back. But it took some time to do so I wouldn't "give" it to you.
