That must be a legal minefield as they'd then be in competition with established CAs that use their browser as sort of a platform (unfair competition or something). Being a CA also seems to be a messy business, I don't now if Mozilla would have the resources to do that. Google seems to have a CA of their own, but they don't seem to be signing certificates other than their own with it.
