It works for me and I don't go on many unsecure sites so it is not an issue for me.
Firefox - for it's tools.
Chrome - for web browsing.
Explorer - ew!
Mozilla. Internet Explorer immediately loses, mainly because it's slow and sucks in general. And Chrome loses, because it doesn't have that many addons, not only that, but FF has more options.
Currently, I use FireFox. I've never tried Chrome, but Mozilla works fine for me so I don't see any reason to bother switching.
I use Chrome because neither IE or FF worked very well on my six year-old laptop. I mainly use it now just because I'm used to it, and it's not loaded with a bunch of ad-on crap that I won't use.
Main reason: a lot faster.
