Strange Issue while Google Font Rendering

Question

So I am using the fonts this way

<link href='http://fonts.googleapis.com/css?family=Fira+Sans:700|Open+Sans&text=1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz%20' rel='stylesheet' type='text/css' />
<style>h1, h2, h3 {font-family: 'Fira Sans', sans-serif; line-height:1.125em} </style>

This is the result...

I am completely confused as how this can even happen? What am I doing wrong. The issue seems only on the home computer. Rest everywhere I checked its fine.

Home PC: Firefox, Windows 7 (In chrome the fonts are not displaying at all, its blank)

Try using Mozilla's CDN instead of Google's; the latter seems to be buggy with regards to the Fira Sans font.

Replace your googleapis.com link with this one and it should work:

<link href='https://code.cdn.mozilla.net/fonts/fira.css' rel='stylesheet' type='text/css' />

You might have to still use Google's CDN for Open Sans, in addition to Mozilla's for Fira Sans, but Open Sans doesn't seem to have this issue as far as I am aware of.
