What are the extensions for classmates to filter content?

Question

Google Chrome

I would like to warn the brains of the parent from cotton content in this social network. For example, in some plugin there, create a list of groups that will not be displayed in the news, or, for example, do not show recommended cotton videos, close comments in cotton communities so that the parent does not read the streams of cotton patriotism. In principle, it would be nice to find the same thing for VKontakte.
