Firefox not loading cross domain name fonts ( CORS )
You need to add the Access-Control-Allow-Origin header to your font files.
Add the following piece of code into your .htaccess file:
*make sure you have "mod_headers" enabled in your Apache Config
Add this to your nginx configuration file (usually under /etc/nginx/nginx.conf )
After you do this update on your origin, please run a purge all on your CDN Resource and wait a few minutes - then the problem should be fixed.
If you still see missing fonts then please contact our Support via email@example.com or by chat in the bottom-right corner.
