The plugin works, but…

Hi, @elephant1!

It is not possible and you can check source code of the plugin here: https://github.com/gruz0/remove-noreferrer.

I never added third-party scripts or advertisements. You need to check installed plugins on your site. Also I recommend you to deactivate my plugin and check your site again.

Really the problem is not your plugin! Advertising is shown only in the google browser in the mobile version.
