It does not completely block a website. I blocked a website with the addon and that blocked site still could leave some cookies on my browser. So, the addon still allows a blocked website to establish a connection, although a short one, still enough time to leave cookies. If you look for an extension that completely blocks any connection so a website won't find out your IP address, that one ain't doing it for you.
