Blocking a Website

I’m going to block a Website, How can I do it in firewall?
For example, or, etc.

At the time I’m reading this, it shows it has been read 233 times. Wonder why.
I bet it’s not because it’s near impossible to do it using the instructions in the guide.
Why this topic cant be expressed in simple English and actually work is way beyond me.
I don’t know if I’ll ever figure it out.

Oops, make that 332. Darn Dyslexia.

This topic was created in April of 2013, I do not believe website filtering was a part of Comodo Internet Security at that point, the closest thing you came to domain blocking at that time was Host Names which aren’t really the same thing and they’re generally inaccurate when it comes to websites filtering, hence it wasn’t really possible/feasible at the time this topic was created, however CIS has since added website filtering and you can find the help file for it here.

Edit: If you find the help file to be hard to understand then I can try to answer your questions, if you have any.
