It's a mix of strict politics and financial problems. Millions of dollars may sound like a lot, but those are some of their only sources of income and they rarely seem viable. Google has hired Lars Bak and many distinguished WebKit and Runtime environment developers to make a high performance browser. They're practically leading the standards, the aging Gecko/SpiderMonkey codebase can't keep up because no one feels secure working for a dying company that likely doesn't have a competitive salary. That combined with how little a development team there is to work with. To work on the technical side of Firefox is philanthropic at this point, to steer away from Chromium dominance.
