AdGuard Extra is a browser extension that is supposed to fight ad blocking circumvention attempts which become more and more popular. Regular ad blocking rules do not allow us being as flexible as it's necessary, that's why AdGuard Extra was developed.
AdGuard Extra is a companion extension, it is supposed to be used with a full-scale ad blocker like AdGuard or any other. It provides no user interface save for the extension icon in the toolbar. Your browser should allow you to hide the icon if it annoys you.
Please note that it is only useful on a limited set of websites, and it does nothing on the websites not from this list.
Here's the list of websites where this extension can be useful:
