@font-face firefox 3.6.3 problems

hey, are there any bugs with @font-face in firefox 3.6.3? i'm having trouble getting the font to render.

i'm calling the font like this...

then

/* import stylesheets and hide from IE/Mac \*/
@import "fonts.css";
@import "morestyles.css";
/* end import/hide */

then

@font-face {
font-family: 'MyFont';
src: url('font.eot');
src: local('☺'), url('font.woff') format('woff'), url('font.ttf') format('truetype'), url('font.svg#webfont') format('svg');
font-weight: normal;
font-style: normal;
}

then

h2 {
font-family: 'MyFont', sans-serif;
}

everything seems to work in safari and explorer. not sure whats up with firefox.
