I don't trust Google at all. Even though I still use gmail ... habit, I guess. So Chrome is definitely out for me. I search with Startpage, and I use Firefox for the control, like others have said. It isn't perfect, but I feel like it beats all alternatives even with the downsides. I use Ghostery, Privacy Badger (I really like both of these, actually, and I do support and trust the EFF, which makes PB a no-brainer), and AdBlock Plus. I should probably get NoScript on here too.
