@Font-face dynamic loading of <link (...)>. Working everywhere(Chrome, IE8, Safari) EXCEPT FIREFOX!

I'm making a plugin for wordpress. I'm dynamically loading font to tinymce

//load font to iframe
fu开发者_JAVA百科nction loadFontFace(fontId)
{

    var iframe = jQ('#content_ifr').contents();
    var head = iframe[0].getElementsByTagName('head')[0];
    var linkElement = jQ(document.createElement('link'));
    linkElement.attr({href: 'http://fontsforweb.com/font/generatecss/?id=' + fontId, rel: 'stylesheet', type: 'text/css'});
    linkElement.prependTo(head);
}

Works everywhere except Firefox! Firebug in network tab shows that CSS and also TTF font files are loaded but I see no effect.

I'm not going to use webfont loader because it's ALMOST working.

In htaccess:

<FilesMatch "\.(eot|otf|woff|ttf)$">
 Header set Access-Control-Allow-Origin *
</FilesMatch>

Solved the problem

After HOURS of SEARCHING it looks like I'm getting there! I can see that TFF file in firebug's net tab has only 1KB. But it have 17KB. Solution will be here soon by myself I hope:)
