An extension should be able to reload the content of Page Info for a different document. With this patch, an extension can set new values for gDocument and gWindow and then call the resetPageInfo function. This feature can't be implemented entirely in the extension that uses it because other extensions will need to provide a function to clear the information they display before the new information is loaded. The patch adds a new hook (onResetRegistry) for that purpose.

If you set value attributes on all the radiobuttons then you can do radioGroup.value = initialTab; and it will select the radiobutton with the matching value.
