Integrated browser based configuration and control utility at http://config.privoxy.org/ (shortcut: http://p.p/). Browser-based tracing of rule and filter effects. Remote toggling. Web page content filtering (removes banners based on size, invisible web-bugs, JavaScript and HTML annoyances, pop-up windows, 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. HTTP/1.1 compliant (but not all optional 1.1 features are supported). Support for Perl Compatible Regular Expressions in the configuration files, and generally a more sophisticated and flexible configuration syntax over previous versions. Improved cookie management features (e.g. session based cookies). GIF de-animation. Bypass many click-tracking scripts (avoids script redirection). Multi-threaded (POSIX and native threads). User-customizable HTML templates for all proxy-generated pages (e.g. "blocked" page). Auto-detection and re-reading of config file changes. Improved signal handling, and a true daemon mode (Unix). Every feature now controllable on a per-site or per-location basis, configuration more powerful and versatile over-all. Many smaller new features added, limitations and bugs removed, and security holes fixed.
