Hide Khan Academy Comments

Hides the section of Khan Academy courses that contains the sections: Question, Tips & Thanks. This conversation area can be treated as an unmoderated chat space for students. When those students are in a walled-garden at school and the school/district cannot manage Khan Academy, this extension will help maintain student privacy and prevent unmoderated chatting. Google admins wanting to use this in their domains should force install this extension on student Google accounts with Developer Tools disabled otherwise they could use the Inspect Tool.
