Making Java Script pass the firewall security

I'm coding a simple web page on my computer and I wanted to mae pop ups for the picture pages but every time I load it the firewall restricts it and I need to allow it every time, I was wondering how do I make it pass it's inspection so that possible future viewers and I wouldn't need to allow it all the time.

This is the Java Script I'm using:
<script language="JavaScript">
<!--hide
function OpenPopup(htmlfile)
{
window.open(htmlfile, "myWin", "status=no,scrollbars=yes,width=400,height=300");
window.event.cancelBubble = true;
window.event.returnValue = false;
}
//stop hiding-->
</script>
