Have been disappointed for a while that this isn't a thing, Startpage and Firefox (with some add-ons) are imo the best option for protecting your privacy, it would be great to make it easier for unexperienced users to choose Startpage.
I've often wondered why Firefox didn't have Startpage (formerly Ixquick) as their default search engine. Since they both began with privacy as their focus, I thought it would have been a natural choice.
