Yeah, I mentioned this in another comment: it's really a shame that Mozilla spends the majority of that money (often poorly IMO), instead of putting it into an endowment fund or something similar that would leave them in a much better position for the long run.
It actually takes a lot of people to build and maintain a modern competitive browser. Not paying those people and instead investing the revenue would end the project in short order. Mozilla is already outgunned on staff by the other major browser makers and you want us to cut staff to save more? That's not realistic, IMO.
I think that if they cut back on some of the other projects in the short-term, they could ensure the foundation was funded for the long-term - to support Firefox and anything else they deem valuable.
