Adblock Plus

Hi, I've tried a lot of different rule combinations but I can't seem to get the block to only work on a specific website. Every rule I've tried always also blocks the tube on other sites. How would I go about this? Any help is much appreciated.

If the website on which you want to block YouTube is example.com, the you should add this rule in your custom filters: If you want to block YT on example1.com and example2.com then add this: More info on http://adblockplus.org/en/filter-cheatsheet#options
