That's a standard Javascript warning message that's displayed in Chrome when loading resources from 3rd parties (Facebook, Youtube, Vimeo, etc) and there's nothing that can be done about it. Basically, Chrome is warning you that a Javascript file from another domain is being loaded from the current page.
If you are experiencing any problems that you think are being caused by this, definitely let us know. There is no 'workaround' though as it's simply a warning message and not really a notification that something is broken.
I hope that helps explain,
