We built the extension that blocks ads, trackers and third-party cookies

UltraBlock is a adblock and privacy protection browser extension for Chrome, Edge and FireFox. It makes websites load super-fast and prevents third-parties from tracking you online.

External services can detect your exact location, device, browser, behavior and in many cases track you while you visit different websites. UltraBlock uses this database to identify and block unnecessary ads and trackers making your browser faster and protecting your privacy. UltraBlock automatically deletes third-party cookies, clears the cache ow your browser so images can’t be tracked and can even randomize your user-agent.
