You’re welcome.
However, you should use the mask that I showed facebook.com/ note the / after the com and before the *. This ensures that it is actually facebook that is blocked and not a facebook sub-domain of a different site, for example facebook.comcast.com I don’t know if this is a legit name (just an example).
There must be tens/hundreds of thousands of domain names beginning with com and they might have a sub-domain relating to facebook, but isn’t actually facebook.com. So I try to be careful in the use of URL masks as they can have unforeseen circumstances.
