AdGuard browser extensie

AdGuard is the fastest and most lightweight ad blocking extension that effectively blocks all types of ads on all web pages! Choose AdGuard for the browser you use and get ad-free, fast and safe browsing.
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 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.
Version history

Ad blocking has been enhanced in this version by adding support for several modifiers. We've also integrated the extension with our web reporting tool, details below. As usual, all spotted bugs have been fixed too, this mostly concerns Firefox version.


[Added] Integration with #894

A new convenient way to report any issues with websites, be it missed ads, false positives, unblocked social widgets etc. Just head to the problematic website, bring up the context menu and select "Submit a complaint" option. You will be transferred to and a wizard will take you through the required steps to report the issue — and most of the fields will be even filled out automatically. Try it!

    A long time has passed since the last release. But we weren't sitting on our hands. We fixed a whole lot of various bugs, so most users will find something positive in this update. This version also contains some sweet additions that will be interesting mostly for rule creators.

    [Improved] $important modifier was added to the rule constructor: #626

    This one is a rather obvious: when you use the manual blocking tool to create a rule, you can now give this rule a higher priority by ticking the checkbox. The `$important` modifier was available before, but you had to manually add it via the user filter.

    [Added] $csp modifier support: #685

    This is strictly for the rule creators, as it requires the basic understanding of the Content Security Policy security layer.

    This modifier completely changes the rule behaviour. If it is applied to a rule, it will not block the matching request. The response headers are going to be modified instead.

    You can find the syntax and examples for `csp` inside the issue.


    We had been waiting for this for a long time, it took a lot of time but now the code is much more simple and convenient to work with.
