uBlock Origin Lite

What uBlock Origin Lite is

uBlock Origin Lite is a free, open-source content-blocking extension based on the Manifest V3 API. It blocks ads, trackers, miners, and other content after installation. Its default rules include uBlock Origin's built-in filter lists, EasyList, EasyPrivacy, and Peter Lowe's ad and tracking server list; users can enable additional rulesets. Custom filters and filter lists are available, alongside an element picker and cookie-popup blocking. Filtering is declarative, so the extension does not need a permanent process to block content. The project says the browser handles CSS and JavaScript injection, and that Lite itself uses no CPU or memory while blocking. It also says the extension collects no data and makes no remote requests except to fetch filter lists users explicitly subscribe to. Users can permit filtering across all sites by default or choose reduced host permissions. Packaged rules and scripts update with the extension, while subscribed remote lists are fetched when enabled. The project cautions that Lite is not an automatic replacement for uBlock Origin and may be less effective against anti-content-blocker sites or at preventing site breakage.
