jQuery on Firefox
<p>I am new to jQuery.  I am studying Javascript and jQuery and when I open the jQuery programs from the course (not my own programs but the course programs) I get an error in that it says that $ is not defined starting at the ready function.</p>

<pre><code>$(document).ready(function() {
</code></pre>

<p>Any ideas?  I am new to jQuery so I need babysteps.</p>
