Fine in IE7 but not FF

[nshack31]

i have a thick left hand border that does not show in firefox, the css is...

#container{
margin: 0 auto;
 background-color:#ffffff;
 width:465px;
 border-left:335px solid #8FADB4;
 border-right:1px solid #8FADB4;
 border-top:1px solid #8FADB4;
 border-bottom:1px solid #8FADB4;
 background: url('images/br_logo.jpg') no-repeat bottom right;
}

does anybody know why the left border does not show?

thanks
