What uBlock is
uBlock is a free, open-source ad blocker from the maker uBlock, based in Atlanta, Georgia. Its browser extension automatically blocks ads, pop-ups, and trackers; its help center also says it protects against malware. The extension activates after installation and is designed to need little customization. Users can pause it to allow ads temporarily or disable it on particular sites.
The official website links to browser add-ons for Google Chrome and Microsoft Edge. The listed platforms include extension, web, and Windows, while device coverage is described as browser-only. uBlock characterises the extension as fast, memory efficient, and lightweight. Its site links to the GNU General Public License version 3 (GPLv3). EasyList is always installed, but custom filter lists and an element picker are unavailable. Chrome builds use Manifest V3 starting with release 24.0.3.
The extension collects anonymous usage details such as its version, preferred language, browser and operating-system type, and an anonymous installation ID. uBlock also says it uses Cloudflare Analytics for aggregated traffic and usage information, and Sentry to gather error details and device information for debugging. Its privacy policy says request-log IP addresses are hashed and the original addresses deleted immediately. The help center offers a support request form and an email address, and states that uBlock is independent of uBlock Origin.
