Strange WP Theme Nav Icons?

[AussieDave]

Firefox 31.0 (not doing it in IE and in Chrome it's displaying a < li > box icon.

Any idea what this is (circled in red) and what would cause it?
I've checked style.css and the navigation classes don't pull any images nor does the CSS reference any base64.

This is a sub/child menu

Input or help is appreciated

Did you try to use Inspect Element/Firebug or whatever your browser has to check?

Thanks Mac totally slipped my thought process. That nailed it. Seems it's referencing an unknown character set in FF. I'll now use a work around, cheers!

Turns out it's the FontAwesome content: "\f054"; reference which seems to be causing an issue in FF 31.0
The Font family was referenced on a single line and the content another BUT should be combined. Seperate works for Chrome and IE but FF was being sensitive.

Was:
font-family: 'FontAwesome';
content:"\f054";

Changed to this:
font-family: 'FontAwesome' content: "\f054";

fixed it
