# Short-Description: Privacy enhancing HTTP Proxy
# Description:       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.
