Chrome's marketing budget is nearly as large as Mozilla's entire budget. They spent a couple of years actively targeting Firefox users with Chrome ads on the frontpage of google.com, and got Adobe Flash and Java and most of the free antivirus solutions to auto-install Chrome and make it the default browser.

I have yet to hear anyone on HN present an argument for how Mozilla could effectively counter that onslaught. Certainly not without using methods that they would also have complained about. (Though nobody seems to hold Chrome's bloatware tactics against them for some reason).
