Some Fontawesome icons not displaying in Safari

Question

I've noticed a problem when using Fontawesome with Safari (on Mac OS X Mavericks). Some icons, such as Twitter, Instagram etc. do not appear. At first I assumed they were removed because of a copyright issue, but they work fine in Chrome. Here's a screenshot of Safari vs Chrome, and the missing icons in Safari. The web inspector doesn't display any errors. It works displays fine in MobileSafari too.

Does anyone know the reason why only a few icons wouldn't show up? Is there a fix for this? Thanks!

EDIT Turns out the AdBlock extension for Safari was causing this issue, its back to normal when AdBlock is disabled.
