Lining up a list with css

I want to line up a list vertically. Look at the left side of this blog.

It looks fine in IE7, but in firefox the list is indented

here is my css

#right {
	float: right;
	color: #FFFFFF;
	width: 210px;
	padding: 3px;
	voice-family: "\"}\""; 
  	voice-family: inherit;
#right ul {
	margin: 0px;

#right a {
	color: #FFFFFF;
	font-family: verdana;
	font-size: 10px;
	font-weight: normal;

#right li {
	background-color: #4c4c4c; 
	padding: 2px; 
	font-family: verdana; 
	font-size: 11px; 
	margin: 3px 0 0 0;
	list-style: none;
