//I found out that I’d need to close Facebook dialog that I invoke by calling:

FB.ui(<parameters>, <callback>);

//Facebook, doesn’t provide any documentation do these dialogs, with one exception - how to open them, so I had to manually trace how they close the dialog window. I found out that it’s a good practice to open all their dialogs like this
//open the dialog and save off the reference
var dialog = FB.ui(<parameters>, <callback>);
...

//force close the dialog via it's id accessible through the saved reference
