@font face rules loading fonts twice?

On a I'm working on the custom font is being requested twice. Basically when I view开发者_如何学Python the net panel on firebug it shows all two of four custom fonts being requested 2 times.

I've checked the css and they are only being declared once.

Any ideas?

It looks like you're experiencing this bug:

In short, Firebug is causing the issue. Insane, right?

I tested your site with Wireshark (a lot), and the fonts are only downloaded twice while Firebug is active.
