Safari. How to send message from popover to global

In essence you don't need to because you still have access to the safari.extension object in your popover.

So instead of sending a message 'foo' you can simply make a function inside your global page called 'foo()' and call it like so from your popover:

safari.extension.globalPage.contentWindow.foo();
