Good question, I actually went through their budget report a few days ago. I'm not from the states but they seem to be spending over 300 million dollars a year on developer salaries alone. And considering they're HQ'd in Silicon Valley I guess that's not so strange. The bulk of their income is from Google donating 450 million USD every year just to remain the default search choice. That shouldn't reflect poorly on Mozilla, it should make you question how Google can just throw 450 million dollars on remaining the default search choice in a browser with 1% market share. It should make you question the massive monopoly that is Google, not Mozilla who are struggling to make open source software for people.
