I have used this add-on before for myself and in most cases it is capable of blocking adult content sites. I think it will be of great help in my plan to break my self-harming addiction.

It filters out webpages what have names 'similar-to-porn'.

It's good, but why the actual hell is the word "Illustration" blocked? This extension could really do with a whitelist

So far this is a wonderful extension, however, it would really be nice is you could blacklist/whitelist sites and keywords such as Foxes.com and/or hot Latinas, to further protect young prying eyes!

Hope to see further development with these features. added into it .

Cheers!
