I suspect it's because Firefox exploits have looked the same for the last several years -- there has not been a lot of novelty required to implement an exploit, given an arbitrary read/write primitive.

P0 does report vulnerabilities to Firefox though, and they obviously get fixed, they're just not particularly interesting to exploit.

An arbitrary write primitive in the chrome render process hasn't been game over for quite some time.

Perhaps that'll change once Project Fission lands in the stable release
