Why are my bullets to the left of my list in Safari, but above the list in Firefox?

CSS code:

body {
	background-image: url(http://www.viggoknudsen.com/background.jpg); /*background image*/
	}
	
.header {
	position:fixed;
	top: 20px;
	left: 20px;
	}

#navigation {
	position:fixed;
	top: 142px;
	left: 30px; /*left position of navigation*/
	width: 190px; /*width of menu*/
	}

#navigation ul {
	list-style-image: url(http://www.viggoknudsen.com/test/bullet.png);
	list-style-position: inside;
	margin: 0;
	padding: 0;
	margin-bottom: 0; /*bottom spacing between each UL and rest of content*/
	}

#navigation ul li {
	padding-bottom: 2px; /*bottom spacing between menu items*/
	}

#navigation ul li a, #navigation ul li a:visited {
	font: normal 12px Arial;
	color: black;
	background: #F1F1F1;
	display: block;
	padding: 5px 0;
	line-height: 17px;
	padding-left: 8px; /*link text is indented 8px*/
	text-decoration: none;
	}

#navigation ul li a:hover { /*hover state CSS*/
	font: normal 12px Arial;
	color: black;
	background: #E1F0A1;
	display: block;
	padding: 5px 0;
	line-height: 17px;
	padding-left: 8px; /*link text is indented 8px*/
	text-decoration: none;
	}
