Rated 4 out of 5 stars

You can't block all sites while whitelisting a few at the same time.
For example, I want my son to watch netflix, youtube, etc while blocking all other websites with the * code. Impossible! I had done this in 2012 with another add-on but I can't find it anymore.

This review is for a previous version of the add-on (3.02).
