uBlock Origin - Free, open-source ad content blocker.
uBlock Origin is not just an “ad blocker“, it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature. Developed by Raymond Hill.
uBlock Origin is a free and open-source, cross-platform browser extension for content filtering—primarily aimed at neutralizing privacy invasion in an efficient, user-friendly method. It is a general-purpose blocker that blocks ads, trackers, and malware sites by default, using EasyList, EasyPrivacy, Peter Lowe’s Ad server list, and uBlock Origin's own filters. It is designed to use minimal system resources, and is highly customizable, allowing users to create their own filters and rules.
