Firefox development is funded almost entirely out of Google's massive donations to Mozilla. For Google, it's no more than a regulatory hedge - something they can point at and say that Chromium and Webkit are not a duopoly. But the flip side is that if Firefox were to ever become a real threat, Google pulls funding and Firefox is toast.

So if we want Firefox to ever seriously compete with Google products, the first thing we need to do is fund Mozilla. When a company's entire capex comes from a monopolistic competitor that would rather see it dead, any talk about capex is bikeshedding.
