AdBlocker Ultimate started as a free browser extension that blocks ads, disables tracking, and blocks domains known to spread malware. It is available for Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera. Today it has expanded into a full product family: dedicated apps for Windows, macOS, Android, and iOS bring the same no-compromise approach to your entire device, not just your browser.

AdBlocker Ultimate uses extensive filter lists to identify and block all kinds of ads — YouTube commercials, pop-ups, banners, video ads, and more. Unlike other ad blockers, we do not whitelist websites, advertisers, or ad networks. Blocking ads speeds up page loading, reduces CPU and memory usage, and removes distractions.

You can whitelist specific websites you trust and want to support — but that choice is always yours, never ours.

No. We will never show you ads unless you specifically whitelist a website yourself. It has become common practice for some ad blockers to be paid by advertising networks to let their ads through. We stand firmly against this — AdBlocker Ultimate blocks all ads, no exceptions.

The only data we collect is what is necessary for the product to function. We take the privacy of your personal data seriously. For full details, see our Privacy Policy.
