You'll never get to play alongside big boys like Apple and Facebook with this 'talk to upstream' attitude of yours. That's just not how the game is played.
The beauty of open source is that if the maintainers of libjpeg-turbo want to incorporate it, they can, and I'm sure the Mozilla devs would be more than happy to help.
