Mozilla can't stand up to that, which is why I mentioned that Google would need to cease all promotion of chrome (including cross-promotions in other Google products).

But that alone wouldn't suffice. From what I've seen of Mozilla's efforts to promote Firefox, they don't have any idea of how to appeal to the broader audience, or really any audience beyond the privacy-conscious. That Firefox allows better control of one's data is great but it's not nearly enough to carry most people past the friction point of switching browsers. For that you need things like major advantages in battery life and features that fix common web browsing annoyances.
