icoMoon fonts doesn't show-up on Firefox

Question

Haven't some issues with the cross-browsers with the icon replacement fonts on Firefox, currently only show-up the content text but not the icomoon text replacement. Source code shown from code Sass + Magento + .htaccess, any idea or help would be much appreciated.

Had done .htaccess rewrite:

AddType image/svg+xml svg svgz
AddEncoding gzip svgz
AddType application/vnd.ms-fontobject eot
AddType font/truetype ttf
AddType font/opentype otf
AddType application/x-font-woff woff

<FilesMatch ".(ttf|otf|eot|woff)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Origin "http://www.phoebessecret.co.nz"
Header set Access-Control-Allow-Origin "http://skin.phoebessecret.co.nz"
Header set Access-Control-Allow-Origin "http://js.phoebessecret.co.nz"
Header set Access-Control-Allow-Origin "http://media.phoebessecret.co.nz"
</IfModule>
</FilesMatch>

CSS:

@font-face {
font-family: 'topshops';
src:url('../fonts/topshops.eot');
src:url('../fonts/topshops.eot?#iefix') format('embedded-opentype'),
    url('../fonts/topshops.svg#topshops') format('svg'),
    url('../fonts/topshops.woff') format('woff'),
    url('../fonts/topshops.ttf') format('truetype');
font-weight: normal;
font-style: normal;}

.icon-fonts {
    font-family: 'topshops';
    font-style: normal;
    speak: none;
    -webkit-font-smoothing: antialiased;
    font-smoothing: antialiased;
    text-rendering: optimizeLegibility;
    font-weight: 400;
}

.iconsearch {
    content: "\61";
}

Answer 1

Try to add this to your .htaccess file. It should fix your issue. It fixed mine.

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

I was having issues with icomoon and Firefox as well. Have you tried Paul Irish's 'bulletproof' @font-face syntax? It's a little different than what icomoon outputs and I've had better luck with it - no FF issues since.

@font-face {
    font-family: 'Graublau Web';
    src: url('GraublauWeb.eot?') format('eot'), url('GraublauWeb.woff') format('woff'), url('GraublauWeb.ttf') format('truetype');
}
