Yikes!
I don't know how serious the problem really is, because I don't compile Firefox on any regular basis and firefox absolutely rocks for my needs, but this is a horrible portent. I don't even know how they would necessarily fix the administration problems. Do they have an infrastructure in place?
Nothing serious. Mozilla is now dropping less popular packages as
SeaMonkey, and this is usual behaviour.

Don't worry too much.
