I searched the net for it, checked out w3, checked all sorts of forums of people asking it, but nobody knows what it is and what it does.

So here’s how I found it on apple’s site:

body {
-x-system-font:none;
background-color:#FFFFFF;
color:#333333;
font-family:"Lucida Grande","Lucida Sans Unicode",Arial,Verdana,sans-serif;
font-size:12px;
font-size-adjust:none;
font-stretch:normal;
font-style:normal;
font-variant:normal;
font-weight:normal;
line-height:18px;
}

I know everything else, but what the hell is x-system-font??

I thought it might have to do with server side fonts but that seems wrong too.

I read it has something to do with Firebug, or at least it is visible trough Firebug. No idea.

Yeah same here. But this is some kind of firebug bug? Kinda odd when it’s in there, but not coded.

I think its a piece of the browser code, open firebug and you have the change that you will see a couple of tags that aren’t in the code.

Yep, Firefox always puts mysterious things like x-system-font or -moz-background-inline-policy into css, but I have no idea what it means :)
