@font-face not working in Firefox?

This is code generated from FontSquirrel, and working great in every other browser (including IE), but not the mighty Firefox! What am I doing wrong?

(ps- I am using FF3.5)

If you can't view my example, here is the source:

}
@font-face {
font-family: ChevinExbold;
src: url(uploads/fonts/cheviextbol-webfont.eot);
}

/* Styles */

Thanks!

Firebug shows that good old Foxy tries to load the *.eot versions, seems stupid but it simply loads the last definition.

You should wrap the IE part with a conditional comment:

<!--[if IE]>
@font-face {
font-family: ChevinLight;
src: url(uploads/fonts/chevilig-webfont.eot);
}
@font-face {
font-family: ChevinBold;
src: url(uploads/fonts/chevibol-webfont.eot);
}
@font-face {
font-family: ChevinExbold;
src: url(uploads/fonts/cheviextbol-webfont.eot);
}
<![endif]-->

Other way would be to put the IE definitions at the top.

Some bugs:
https://bugzilla.mozilla.org/show_bug.cgi?id=472647 - Either ignore .eot or support it
https://bugzilla.mozilla.org/show_bug.cgi?id=520357 - "We do not (and will not) support EOT."[sic]

Yeah, usual Mozilla unpropress.
