Add second option for Firefox Add-on polyfill

and changed link text to indicate the add-on's name(s).
Also removed locale string from Firefox Add-on link(s), so Mozilla's site will auto-detect the browser's language/locale.
Added Polyfill for Firefox 3.5-21 support.

While Firefox 22 is just around the corner there has been a polyfill around for a while, and now that I know of CanIUse I thought it should be added to the list.
Update x-doc-messaging.json

IE10 still does not have full support. It fails to postMessage silently when hostnames are different, but succeeds if the hosts are identical with different ports.
