No. Considering the amount of manhours which are sunk into this nigh bottomless pit, $10.000 is a laughable amount of money. I doubt you'd be able to hire a professional programmer for more than 3 or 4 months for that amount. Outsourcing to China or India gets 3, maybe 4 programmers, I think.
Apart from that, the non-rewarding part stems from the fact that it is rather low-level stuff which isn't very visible nor endowed with a high 'wow! cool!'-factor. To the user, it isn't really special when a window with a few gadgets is put on-screen, while in fact this is a very, very tough nut to crack in this project.
Have you ever tried Amigafying a program which is breathing Unix at every line of code? I have, and that was a program 100 times smaller than Firefox which didn't use any graphical UI nor publically available low-level libraries such as GDK, GTK+, libpng, and the like---in the end I got so fed up that I simply used the program on my PC instead. (The nasty proneness to crashing of the Amiga made coding a hell, too.) The people toying with the Firefox port are in effect backporting 10 years of software engineering advances on the Unix-platform to a platform which, while sharing some rudimentary characteristics, operates in a radically different way, nor is really supportive of projects of this magnitude and complexity. But hey, it's their spare time, not mine. To each their own.
