My understanding of ABE, with the default facebook containment rule, is that it allows Facebook to run scripts only while you're on facebook.com. But recently I noticed this:

Why does this facebook element work? I thought this was exactly the kind of thing ABE is supposed to block. Have I misunderstood something or has Facebook and/or Seamlessweb managed to get around ABE?

ABE is like a blacklist, allowing everything by default and requiring explicit denies to block something. There's a "Deny INC" missing from your rule.
