Privoxy is a web proxy with advanced filtering capabilities for protecting privacy, filtering web page content, managing cookies, controlling access, and removing ads, banners, pop-ups and other obnoxious Internet junk. Privoxy has a very flexible configuration and can be customized to suit individual needs and tastes. Privoxy has application for both stand-alone systems and multi-user networks. Privoxy is based on the code of the Internet Junkbuster (tm). Junkbuster was originally written by Junkbusters Corporation, and was released as free open-source software under the GNU GPL. Stefan Waldherr made many improvements, and started the SourceForge project to continue development. Privoxy continues the Junkbuster tradition, but adds many refinements, enhancements and new features.
