My impression is that those who don't care about privacy have already switched to Chrome long ago, and see little reason to go back. And from those who do care, an increasing number (including me) is considering leaving FireFox due decreased trust in Mozilla's self-proclaimed privacy standing. I do wonder which target audience will be left to use FireFox after all then.
I'm not sure what's left after Chrome and FF. Safari if you are on a Mac and IE on Windows (though IE seems imperfect). I suppose you can use a FF derivative like Ice Weasel. For my money, Mozilla is still the best option and with so many free options out there, it's hard to keep up unless you play the game somewhat. Mozilla's most important role is a seat at the web standards table and if they wither on the vine because users jump to Chrome because it "just works", they will lose that seat.
The number of people who care about their privacy in the general population is quite small. We in our tech bubble believe that everybody cares, or should care, but most are satisfied if they find a searched page by entering it “into the Google”.
Those with FF installed it 10y ago when it was sexy, and stuck with it because they are resistant to change.
