Safri, IE, Firefox-Recent Facebook Posts widget no show

I noticed the the Facebook Recent Facebook Post widget, does not show on Safari, IE, or Firefox, it does not show up at all. Only on Chrome does it show up.

I would like to know how to fix this. My website in question is http://www.3elementdesigns.com/ and you can see at the bottom in the footer where there is a “Recent Facebook Posts”, thanks!!
