AdGuard CNAME Lab: Unlocking Advanced Content Blocking Capabilities

AdGuard Content Blocker is a powerful tool that allows users to block requests to specific URLs, providing an additional layer of protection against unwanted content. The extension uses Basic rules, which are simple yet effective in blocking requests based on specific criteria. These rules can be extended using advanced CSS syntax, allowing for more precise control over what content is blocked.

Basic Rules

---------

AdGuard Content Blocker offers three types of basic rules:

* Element hiding rules: These rules hide specific HTML elements from a webpage without requiring any additional CSS support.

* Exception rules: These rules can be used to exclude certain elements or requests from being blocked, using modifiers such as `$document` and `$elemhide`.

* Blocking rules: These rules block requests based on domain, third-party content, or content type, with modifiers like `$domain`, `$third-party`, and `content-type`.

Limitations

---------

While AdGuard Content Blocker is a powerful tool, it has some limitations. The browser's restrictions mean that AdGuard Content Blocker can only support an old Adblock Plus filters syntax, which may not be as effective as other filtering systems.

Trusted Filters

-------------

AdGuard Content Blocker offers trusted filters that can be used to block specific content. These filters are created by the AdGuard team or installed from custom lists. Some rules can only be used in trusted filters, providing an additional layer of security.

Extended Rules

-----------

AdGuard Content Blocker extends CSS and allows filter developers to handle more complicated cases using advanced syntax. This means that users need to have a good understanding of regular CSS to use these extended rules effectively.

Blocking Specific Content

----------------------

AdGuard Content Blocker allows users to block specific content using advanced filtering rules. These rules can be used to block requests based on URL, domain, or other criteria. The extension also supports `$important` modifier, which allows blocking rules to override exceptions.

AdGuard CNAME Lab is a powerful tool that provides an additional layer of protection against unwanted content. By understanding the basics of AdGuard Content Blocker and its advanced filtering capabilities, users can take control of their online experience and block specific content with ease.
