Firefox not rendering @font-face style correctly

Question

Hey guys, for some reason, I have FireFox not complying with the supposed "bullet-proof" method of getting a custom font in every modern browser.

Well, I hope I'm just doing something wrong, because it looks to me as though it really should be working.

Here is my CSS style:

@font-face {
    font-family: 'SMB';
    src: url('/css/type/SMB.eot');
    src: local('ò∫'),
             url('/css/type/SMB.woff') format('woff'),
             url('/css/type/SMB.ttf') format('truetype'),
             url('/css/type/SMB.svg#webfont') format('svg');
font-weight: normal;
font-style: normal;
}
