Privoxy vs uBlock Origin Lite

Privoxy is free, non-caching web proxy software for privacy controls, access rules, and changes to HTTP headers and web pages. It can modify page text, remove banners and web bugs, filter HTML annoyances, and inspect HTTPS requests and responses. A browser-based configuration and control utility includes rule tracing and remote toggling, and Privoxy can be chained with other proxies. It can serve multiple clients across a network or as a LAN gateway. The software runs on Windows, GNU/Linux, Mac OS X, Haiku, BSD variants, Solaris, and other Unix systems. It is licensed under the GNU GPL version 2 or later, with a free plan listed at free. A basic configuration is included with a new installation, but many advanced features need to be enabled. Privoxy handles HTTP and HTTPS proxying; it does not handle FTP, SMTP, instant messaging, IRC, or ICQ. It is not designed as a malware-removal tool, and the default setup does not filter malware. The project says it lacks trusted build infrastructure; individual project members or external contributors build and upload binary packages.

uBlock Origin Lite is a free, open-source content-blocking extension built on the Manifest V3 API. It blocks ads, trackers, miners, and other content after installation. Its default rules include uBlock Origin lists, EasyList, EasyPrivacy, and Peter Lowe’s ad and tracking server list. Users can add rulesets, custom filters, and filter lists, and use an element picker and cookie-popup blocking. Filtering is declarative, so no permanent process is required; the project says the browser performs CSS and JavaScript injection and the extension itself uses no CPU or memory while blocking. The project says it collects no data, has no analytics or telemetry hooks, and makes no remote requests except for filter lists users explicitly subscribe to. Users can allow all-site filtering or reduce host permissions. It warns Lite is not an automatic uBlock Origin replacement and may be less effective against anti-blocker sites or breakage.
