I use this add-on to block Youtube as I started to notice it taking more and more time of my life. This is definitely helping with the addiction.

Excelente complemento. Muy eficiente en su modo de lograr su propósito. Estoy satisfecho con el cuidado. Gracias a los colaboradores por diseñar esta aplicación.

Best extension.

Guys, developers! You can’t even imagine how grateful I am to you! You help me live straight on! The fact is that I constantly went to the page in Vk to my ex-girlfriend, looked at the pictures and suffered and couldn’t forbid myself to do this. Now, I have added a link to her page and her first and last name and all this is blocked and I'm sober right. Plus, I blocked the extension itself with a password, which I just don’t know and that’s all. I can go to the Vk site everywhere, except for her profile. Block other sites - I do not need, and in the most important thing you really helped me! Sincere human thanks !!!

Helps increase your productivity.

Hilarious pictures and comments on blocking events;)
