If you are blocking Facebook frame, I will assume you don't mind blocking the matching Facebook script, so add this rule to your ABP filters:

    ||connect.facebook.net^$script,third-party

Edit: or really, just:

    ||connect.facebook.net^$third-party

i get this: http://i.imgur.com/MoeEuZ2.png which is caused by this: http://i.imgur.com/RwZluqB.png

i fix it by right clicking and choosing inspect element and deleting the node.

i believe the issue i have is caused by barracuda blocking the iframe's content.

Seems to be a bug in HTTP Switchboard extension.

Not a bug. It's just the web page which styled the Facebook frame to be way larger than it needs to be -- given it's just to receive a Facebook button.

Edit: This will happens with anything which blocks Facebook frame, but not Facebook script.

Noticed that too.
