I'm on Firefox 42.0 and web fonts (icons) are not rendered for FontAwesome framework :

Font Awesome

or on Github :


And many others websites.


I have tried to figure out where this came from by comparing pref.js file from a clean install of Firefox and i have found the property that caused the issue :

user_pref("layers.acceleration.disabled", true);

The value have to be on false to solve this issue. Hope this help.
