Con Privoxy, es posible eliminar anuncios, descartar cookies de seguimiento, eliminar ventanas emergentes, bloquear la carga de scripts JavaScript externos y realizar modificaciones personalizadas en las p\u00e1ginas web a gusto del usuario. Privoxy se puede instalar tanto en sistemas locales de usuarios individuales como en servidores para crear una infraestructura de filtrado de contenido centralizada en una red local.
