Answer 3

I have been looking for a solution from about the moment my three-year-old son got hooked on vidos like Om Nom.
We needed a universal solution for a computer and a phone.
I tried several extensions for Chrome, but they simply blocked the viewing of the video, not excluding it from the list of recommended ones.
I came to the conclusion that it is easier to write your own "crutch" that will limit the child from harm:
