Icon-font not visible in firefox

[FreIsaa]

I have added with @fontface an iconfont. The only problem is, that it is not visible under firefox. I have the newest version of firefox. Safari and Chrome are working perfectly fine.\[code\]@font-face { font-family: 'iconFont'; src: url('../fonts/iconFont.eot'); src: url('../fonts/iconFont.eot?#iefix') format('embedded-opentype'), url('../fonts/iconFont.svg#iconFont') format('svg'), url('../fonts/iconFont.woff') format('woff'), url('/fonts/iconFont.ttf') format('truetype'); font-weight: normal; font-style: normal;}\[/code\]
