Much to my dismay, find out that with Firefox 13 changed it's syntax for box shadow. The new one drops the -moz-. So instead of -moz-box-shadow, it's now box-shadow. Here's my revised box shadow and rounded corners CSS:
border: solid 5px #fff;
border-radius: 5px;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
box-shadow: 0 0 2px #888;
-moz-box-shadow: 0 0 2px #888;
-webkit-box-shadow: 0 0 2px#888;
