Privoxy (Privacy Enhancing Proxy) is a non-caching Web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk.
Privoxy has a flexible configuration and can be customized to suit individual needs and tastes. It supports both stand-alone systems and multi-user networks.
Privoxy uses the concept of actions in order to manipulate the data stream between the browser and remote sites.
- Ad blocking.
- Cookie management.
- Supports “Connection: keep-alive”. Outgoing connections can be kept alive independently from the client.
- Supports IPv6.
- Tagging which allows to change the behaviour based on client and server headers.
- Run as an “intercepting” proxy.
- Sophisticated actions and filters for manipulating both server and client headers.
- Can be chained with other proxies.
- Integrated browser-based configuration and control utility. Browser-based tracing of rule and filter effects. Remote toggling.
- Web page filtering (text replacements, removes banners based on size, invisible “web-bugs” and HTML annoyances, etc).
- Modularized configuration that allows for standard settings and user settings to reside in separate files, so that installing updated actions files won’t overwrite individual user settings.
- Support for Perl Compatible Regular Expressions in the configuration files, and a more sophisticated and flexible configuration syntax.
- GIF de-animation.
- Bypass many click-tracking scripts (avoids script redirection).
- User-customizable HTML templates for most proxy-generated pages (e.g. “blocked” page).
- Auto-detection and re-reading of config file changes.
- Most features are controllable on a per-site or per-location basis.
Support: User Manual
