While adding some very basic script tags I found a wierd "bug" in firefox (as well as IE) I added these two lines of code to my .htm page
<script type="text/javascript" src="js/jquery.js" />
<script type="text/javascript" src="js/jquery.corner.js" />
To me as well as opera and chrome they look like ordinary script tags however to firefox and IE they dont recognize them and will not run the scripts. However a simple change to
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/jquery.corner.js"></script>
Fixes the problem. I don't see why this different style of closing tags works on other tags but not the script tag. For example I can close a img tag with either
<img src="img.gif" alt=""></img>
or
<img src="img.gif" alt="" />
