Title icons on Firefox about autm-rb HOT 2 CLOSED

Hi,
Have you seen this article https://support.mozilla.org/en-US/questions/959250 ?

Hello Again. I'm here for say sorry about post this issue here because the problem never wasn't firefox instead was my operative system (opensuse with Gnome 3.8) configuration that cause this bad behavior. The simple reason was the selection of region and language because the most generic language configuration for Spanish is [Spanish from Spain], but my selection was [Spanish from Colombia] this cause the bad behavior in firefox. I change the selection and the problem was solved.

The icons render fine in firefox 40 on mac.
btw I'll update fa cdn link to 4.4.0

from autm-rb.

I had not seen this article, thank you.
I have changed my language and region (tried French, English and Spanish), but the problem persists.
Anyway, the google fonts render fine in my browser, which was not the case in the article you gave, so this is maybe not the same bug.
