What uBlock is
uBlock is a free, open-source browser extension that blocks ads, pop-ups, and trackers on Chrome and Edge. 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 specific sites. The site describes it as fast, memory efficient, and lightweight, and links to the GNU General Public License version 3. The listed plan is free. Release notes say EasyList is always installed, while 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 version, preferred language, browser and operating system type, and an anonymous installation ID. The privacy policy says request-log IP addresses are hashed and the original addresses deleted immediately. uBlock also says it uses Cloudflare Analytics and Sentry error reporting, and cannot guarantee absolute security for collected information. Its help center states it is independent and not affiliated with uBlock Origin.
