Browsers don't allow for scripts to read the contents of inside an iframe for security reasons against XSS attacks. You can only read the contents of an iframe if it has the same origin as the parent site.

Martin Sonesson, that's irrelevant for extensions which can run a content script inside the iframe.

Keval Kankrecha, as I explained in the other thread you have a typo and a possible mistake in the other code that you didn't show.
