It doesn't matter what search engine you use if you use Chrome. Chrome spys on you, too. I use Firefox. Mozilla is an awesome non-profit web advocacy group. Also their politics is libertarian friendly because they rely mostly on affecting market forces rather lobbying government to pass laws. They also have helped organize people against legislation like SOPA/PIPA and CISPA. Firefox isn't all that similar though because it was designed around being highly customizable and extensible, but Chrome was designed to be so simplified that I couldn't make basic customizations when I tried it out.
If you happen to be using Linux, Rekonq is similar, but you're probably using Windows.
