About AdGuard Browser Extension

AdGuard Browser Extension is an ad blocker for Chrome, Firefox, Edge, Opera and Yandex Browser. It blocks ads, pop-ups and tracking scripts, and uses cosmetic filtering to hide leftover page elements.

It is a separate product from AdGuard's system-wide apps for Windows, Mac, Android and iOS, and from AdGuard DNS and AdGuard Home. The source code is published on GitHub, and a release history is available on the AdGuard site. It suits people who want ad and tracker blocking in the browser without installing a system-wide filter.
