I wonder: Is there a way to set-up Privoxy as a man-in-the-middle filtering proxy? The FAQ only says that "Privoxy can't do much with HTTPS URLs", but I believe that is only true if I require the certificates to remain intact. Surely if I were willing to sacrifice that, Privoxy could make a request to the remote server on my behalf, decrypt it, then encrypt it with its own certificate and send it to my browser. It may be that Privoxy lacks this capability, but I don't see any technical reason why this should be imposible.
(Basically, I want to filter my encrypted traffic, even if it means that I lose the "protection" given my by the "trusted" certificates.)
