content: The Content Blocker API allows the developer of a content blocking extension to integrate it into Yandex.Browser so users can block ads -->

If you have developed a content blocker on the Android platform, you can integrate it into the [mobile Yandex.Browser](https://browser.yandex.com/mobile/main/). Then Yandex.Browser users can install your extension and use it for blocking ads and other unwanted content.


{% note info %}

The Content Blocker API is supported in Yandex.Browser versions 16.6 and later.

When a user chooses the extension in the browser settings, the browser requests filters from the extension and uses them to start blocking unwanted content on web pages.

Even if the user installed multiple content blockers on the device, only one of them can be selected in settings.
