Every window opened must be initiated by a user action such as a click. One action, one window. Otherwise, a script could open dozens or hundreds of spam popup windows on one click. Firefox will show a “popup blocked” warning that will allow the second window to be opened if the user allows it, but Chrome will simply block it silently. There really isn’t any way to get what you’re after: two windows will require two clicks.
That is odd as I already have an anchor in the link and it doesn’t fire how you are saying. Let me have a play with it and see if I can get it to work
