? Tor is freely available to any one. Tor browser is so simple my mother uses it. At this point I don't understand why people would do a websearch for something they would not discuss in public without using Tor.
Some sort of super private browsing mode would be nice. I'm not sure I trust Mozilla to get that right though. Their main priority is pushing the Web forward (and keeping up with chrome). Privacy is difficult and conflicts with functionality in some cases e.g. webrtc, javascript, window size etc. The current solution where Mozilla have an lts release that the tor project can use as a base seems quite a good compromise.
