What exactly is the issue? I don't think just throwing more money or people at that specific work would increase velocity. At a certain point you get too many cooks in the kitchen
They want firefox to keep up in marketshare because it can keep as much as you want on your scoreboard... If it isn't used it ends up useless, dead and without a hand in webstandards.

It's worse now.
