I actually don't disagree with this. Even though I'm a pretty tech-savvy Firefox user (and by "tech-savvy", I mean "seasoned Unix administrator and backend programmer"), "Mozilla" is also a household name among plenty of less-tech-savvy folks; I've seen Firefox (often called "Mozilla" or "Netscape" by its users, amusingly enough) everywhere from the most high-tech web development shops to computers owned/operated by seniors and running Windows XP and dial-up internet. Chrome hasn't had that level of adoption yet; while it's certainly popular among the tech-savvy, it hasn't trickled into ordinary households quite the same way as Internet Explorer and "Mozillafire Netfox" have.
It helps that Firefox has a lot of brand maturity in non-tech circles, whether it's referred to as "Firefox" or by the names of its ancestors. It also helps that Firefox is the default browser on the vast majority of desktop GNU/Linux distributions (which are gaining some popularity now that Windows XP is unsupported and being phased out more aggressively), though this probably isn't as significant of a factor as the existing brand recognition/maturity.
