  • Ad blocking
    AdGuard blocks all ads including video ads, interstitial ads and floating ads, pop-ups, banners, advertisements, and text ads. Element blocking feature allows blocking of ANY unwanted element on the page.
  • Privacy protection and safe browsing
    AdGuard protects your personal data by blocking common third-party tracking systems, spyware, and adware. In addition, it warns you about malicious and phishing websites once you try visiting them.
  • Handling adblock circumvention scripts
    AdGuard can handle adblock circumvention scripts. You won't have to turn off the ad blocker anymore to be able to visit the websites that are using such scripts.
  • Next step: AdGuard Assistant
    If you are already using a full-fledged program (AdGuard for Windows or for macOS), you don't need an extension anymore. Instead, install our new AdGuard Assistant. It helps manage filtering right in your browser.
