UltraBlock is a Chrome extension that blocks ads, trackers and third-party cookies, improving website loading speed and privacy protection.

Most websites load dozens of external services in the background, which are used to track and profile visitors. This helps websites improve conversions and sell user profiles, but it can slow down your browser and compromise your privacy. However, with UltraBlock, you don't need to worry about any of that. It automatically blocks unnecessary services, and shows you exactly which services are loaded in the background of the websites you visit.
The UltraBlock tracker database includes 1.941 hostnames of external services, which are categorized into Advertising, Analytics, Social, and Essential. Services that are not necessary for a good browsing experience are marked as 'unnecessary', and UltraBlock will automatically block ads and trackers that you don't need. This helps to make websites load over 53% faster, while keeping your privacy safe.
To protect your privacy as much as possible, UltraBlock starts by blocking content from services that are marked as 'unnecessary' in the tracker database. After that, it cleans out over 80% of trackers, leaving only unknown or new trackers. Then, UltraBlock cleans up the third-party cookies and your browser cache after every website visit. Finally, to make it even harder for services to track you, UltraBlock randomizes your user-agent for each website visit.
UltraBlock is a lightweight and super fast Chrome extension that runs quietly in the background. It can be used by anyone who wants to make their browser run faster and more secure. Overall, UltraBlock is an excellent software for anyone who wants to enjoy a faster, safer browsing experience, without compromising their privacy.
