I can't get font-awesome to display properly in firefox, even in localhost. I'm receiving a cross domain error, exactly what's reported here.
The solution to this problem is to add the following to .htaccess or directly to apache config:
<FilesMatch "\.(ttf|otf|eot|woff)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
But I'm hosting my app in Google App Engine, so how can y set the Access-Control-Allow-Origin in GAE?
