Answer 1

iframes and the main page have to match protocols ( Http:// and Https:// )

a secure site can not communicate with a not-secure site

just make everything secure to make things easier. Sites like Facebook are going to require it anyways.

Answer 2

You cannot access values in the embedded facebook page. That is against the Same Domain Policy. The two sites can communicate using postMessage if you control both sites, but I doubt that you control the facebook part ...

Answer 3

Can you provide some information about the browser where you're getting those errors?

Because Chrome have a know error related with your issue. More info here.
