Ad and Tracker Database

UltraBlock maintains a manually verified Ad and Tracker Intelligence Database with more than 5,400 hostnames. Each service is categorized as Advertising, Analytics, Social or Essential. Unnecessary services are blocked automatically, while essential ones remain active. Inside the UltraBlock popup you can see everything a site tries to load and decide for yourself what to allow or block. This gives you full control to customize your browsing experience exactly as you like it.

Advanced Privacy Protection

UltraBlock goes far beyond basic ad blocking.
• Blocks over 80 percent of known ads and trackers
• Cleans third-party cookies and browser cache after each visit
• Sends the Do Not Track header with every request
• Offers optional User-Agent rotation to make tracking harder
• Lets you manually block or allow services from the popup
• Prevents cross-site tracking and behavioral profiling

This combination of automatic and manual protection makes UltraBlock one of the most complete privacy extensions available.
