uBlock Origin company profile

uBlock Origin provides an open-source browser extension that blocks ads, trackers, and harmful domains across major desktop browsers. The extension uses community-maintained filter lists such as EasyList and EasyPrivacy and supports additional lists for malware, annoyance, and regional rules. It allows custom filters, per-site toggles, and temporary or permanent rules through a dynamic filtering interface. An element picker and logger help identify and block specific page elements or network requests. The project focuses on efficient content blocking with default settings that balance privacy and site functionality. Source code and issue tracking are publicly available, and configuration can be exported or synced between devices.
