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 Anti-Adblock scripts
AdGuard can handle Anti-AdBlock scripts. You won't have to turn off the AdBlocker anymore to be able to visit the websites that are using such scripts. Just send a complaint to our tech support and we'll handle it.
Integration mode
If you are already using a full-fledged desktop program (AdGuard for Windows or macOS), then the extension will undertake the features of Assistant and become a very useful support tool.
User reviews
What's the difference between extensions and AdGuard desktop apps?
The most obvious difference is that extensions only work in their respective browsers. Extensions also suffer from technical limitations that don't allow blocking of certain types of web requests.
What is integration mode?
It is a special mode that the extension enters when being run along with a desktop AdGuard app (on Windows or macOS).
What happens in the integration mode?
In this mode, the extension stops filitering traffic (this function lies completely on the app). Its settings are also ignored, the app's settings are applied instead. The extension's color changes to blue and it serves as a replacement for AdGuard Assistant.
In what browsers does integration mode work?
It works in all supported browsers except Microsoft Edge and Safari.
What does the 'Invert whitelist' setting do?
When enabled, AdGuard ceases to filter all websites by default. To enable filtering on a specific website, add it to the inverted whitelist.
AdGuard browser extensions are a great way to protect your favorite browser from ads!
