how will this affect facebook iframe apps? They load from a different origin, and the user is bound to receive a cross-domain error.

normally, the following would pass:

Unsafe JavaScript attempt to access frame with URL http://apps.facebook.com/my_app from frame with URL http://server-hosting-my-app.com. Domains, protocols and ports must match.

will this blocked by Chrome in the future? if so, everyone running Chrome 14 onwards won't be able to play Farmville.

more info: if you load Farmville on Chrome, this comes up in the debug console (which still passes)

Unsafe JavaScript attempt to access frame with URL http://apps.facebook.com/cityville/?installed=1 from frame with URL http://fb-0.cityville.zynga.com/flash.php?isOuterIframe=1... INFO HERE CUT OUT]. Domains, protocols and ports must match.
