Extensions

Userscripts​

Userscripts (we also call them "extensions") are, de facto, miniprograms written in JavaScript. They modify or extend the functionality of one or more websites. Many AdGuard users may be already familiar with such userscripts as AdGuard Assistant, Popup Blocker, and AdGuard Extra.

Supported apps

AdGuard can significantly broaden website functionality by acting as a userscript manager. You can add your custom scripts or manage the existing ones in our three products: AdGuard for Windows, AdGuard for Android, and AdGuard for Mac.

Recommended AdGuard scripts​

These userscripts come directly from the AdGuard developers, and we can guarantee that they are effective and safe. For some of the userscripts developed by others that we consider good and reliable, scroll down to the next section. You can also find some of the popular websites with scripts below, but remember that whenever you download a userscript from an unknown source, you are exposing yourself to a certain risk, as some scripts may be harmful to your computer.

AdGuard Extra​

An extension that blocks ads in difficult cases when the usual filter-based approach is not enough. AdGuard Extra comes pre-installed in AdGuard standalone apps, except for the one for iOS, so you don't need to do anything to enable it. However, if you want to use it alongside AdGuard Browser Extension or any other ad blocker, you'll need to use an additional extension. Learn more about this userscript and how to install it on GitHub.

AdGuard Extra

AdGuard Popup Blocker​

The name speaks for itself: it blocks popups — one of the most annoying types of ads on websites. Learn more about this userscript, its key features, and installation on GitHub.

AdGuard Popup Blocker

AdGuard Assistant (legacy version)​

This custom extension is designed to control filtering directly from the browser page (manual blocking, allowlisting, etc.).

note

This version of Assistant is legacy and there is no point in using it on new systems, as it has been replaced with the full-fledged Browser Assistant. However, the legacy Assistant may be useful if there is no Browser Assistant for your browser. If this is your case, you can learn how to install AdGuard Assistant on GitHub.

Disable AMP​

A script that is only pre-installed in AdGuard for Android. It disables AMP (Accelerated Mobile Pages) on the Google search results page. Learn more about this userscript and how to install it on GitHub.

Top picks outside AdGuard​

These userscripts are not developed by AdGuard, and therefore we can't give a 100% guarantee that they are safe and/or work at all times. However, in our experience they deserve a recommendation because they've all earned their good reputation.

Don't track me Google​

This script removes Google's tracking feature from the links in Google search results. It speeds up the loading of search results and allows you to right-click or tap to copy the link URL.

Its source code is available on GitHub. This userscript can be downloaded from GreasyFork and installed in any AdGuard CoreLibs-based app.

microShield​

A userscript for people visiting Korean websites and some international websites. The microShield userscript blocks Ad-Shield ads and anti-adblocks. Its original source code is available at asdefuser and AdShield Defuser. This userscript can be installed in AdGuard CoreLibs-based apps, Violentmonkey, Tampermonkey, and quoid/userscripts. Learn more about microShield and how to install it on GitHub.

Where can you get more userscripts?​

Since userscripts are mainly created by enthusiasts, you should be cautious when installing them. Any script from an unknown source carries a potential risk. Yet, there is a great variety of interesting scripts that, if installed carefully and responsibly, can really make using some websites more convenient.

Here we will describe some of the most popular userscript catalogs.

Userscript.Zone​

Userscript.Zone is a website that allows searching for userscripts by entering a matching URL or domain. The website is easy to use and has a high level of credibility as only scripts from moderated pages are displayed.

Greasy Fork​

Greasy Fork is a userscript catalog of Stylish creators. The scripts in this catalog are moderated, so their credibility is much higher.

OpenUserJS.org​

OpenUserJS.org is an open-source userscript catalog written in nodeJS. It's not moderated, so keep an eye out for suspicious scripts.

Userstyles​

Userstyles allow users to customize their online experience. Whether you’re looking to change the appearance of a website or automate repetitive tasks, styles offer a world of possibilities.

AdGuard has the option to upload or create your own userstyles. This is an advanced feature, so you will need some knowledge of HTML and CSS.

Supported apps

Currently, two AdGuard apps allow you to create and manage userstyles: AdGuard for Windows (v7.19 or later) and AdGuard for Mac (v2.16 or later). We also plan to implement this new feature in AdGuard v4.8 for Android in the nearest future.

This is an experimental feature, so if you encounter any problems while adding or creating a userstyle, please contact our support team at support@adguard.com.

How to set up a userstyle in AdGuard​

You can download userstyles from various websites. One of the most popular userstyle websites is https://userstyles.world/, which we will use as an example for the following instructions on how to set up the userstyle in AdGuard.

  1. Follow the link above and choose the userstyle you like

  2. Right-click the Install button and choose Copy Link Address

  3. Open AdGuard settings → Extensions

  4. Press the [+] button and paste the userstyle link

  5. Done!

If you’re familiar with CSS rules, you can also create the userstyles yourself.

note

We don’t support userstyles that contain @var or @advanced in the metadata. AdGuard also doesn’t support @preprocessor without the default value.

  1. Open AdGuard settings → Extensions

  2. Press the [+] button and choose the Create userstyle option. A new window will appear on your screen

  3. To create a userstyle, first write the title with metadata, for example

    /* ==UserStyle==
    @name New userstyle
    @version 1.0
    ==/UserStyle== */

  4. Write the CSS part after the meta data. AdGuard supports website domain names matching (@-moz-document domain(…), …). For example:

    body {
      background: gray;
      }

    Or:

    @-moz-document domain('example.org'),
    domain('example.net'),
    domain('example.com') body {
      background: gray;
      }

  5. Once you’re finished, press Save and Close. Your new userstyle has been successfully added to AdGuard

Example​

/* ==UserStyle==
@name         Example userstyle
@namespace    https://example.org/userstyle
@homepageURL  https://example.org/userstyle
@version      1.0.0
@license      Other
@description  This is an example
@author       example
@preprocessor default
==/UserStyle== */
@-moz-document regexp("https?\:\/\/(www\.)?example\.(org|com).*") {
    body {
        background-color: #000000 !important;
    }
}
