It’s nice to include jquery from Google for performance, less load, etc. But use the secure link!
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
It prevents IE from nagging about insecure content. Anyway, I can also advice on not using IE altogether.
