Nebulae can exist entirely by circumstance, no will required. It's an bad example.

I rated this 4 because it aint perfect but it works. I was still able to access some sites that is still 18+

I really appreciate what this extension does. It doesn't just block porn, it educates you on it, and guides you through somethings to help you shake the temptation. Unfortunately it is just an extension and is very easy to disable. It obviously can't do anything about that but I appreciate it for what it is. It has helped me many times.
