There are some sites (or rather, domains) that I do not want to allow globally. For instance, Twitter and Facebook are represented on millions of other sites that embed live information from them, including scripts, and I want to block them there. But I may still want to visit Facebook or Twitter directly, and then their scripts should be allowed or their sites won't work.
I have 'Temporarily allow top-level sites by default' turned off, and I intend to keep it that way. But I guess what I want is to allow some sites (like FB and Tw) when, and only when, they are the top level.
How do I accomplish this? Thanks in advance for any replies!
