opener.close()window.openernull". window.opener works fine in both IE and Firefox as long as Open in New Tab is used from the right-click menu Error console says window.opener is null. Is there any other way the opener can be accessed? in Firefox its working but in IE window.opener null . Reason is cross domain . if Third party URL is in current domain then it works fine but if its cross domain windowReference gets null to get it working i have to change Internet Settings->Security->Check Enabled its almost impossible to do at every client The action references the opener window, removes a few elements from a hidden element and then immediately repopulates those elements with updated values based on that action.
