Open a link to a local file or execute the window.open from within the iframe.
In Google Chrome, links to local files are disabled, unlike IE. This extension allows you to open a link to a local file by clicking it. Execute window.open from iframe from cross origin. It is disabled by default in chrome. [Security] A malicious page can not open a local file without permission, because this extension reacts only to the click operation by the user.
