Like adelphus said, it's only a variable usd by Firebug as an xpath shortcut. You can implement it with this code:
function $x(path){
var xpath = document.evaluate(path, document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);
var temp = [];
for (var i = xpath.snapshotLength - 1; i >= 0; i--) {
temp.push(xpath.snapshotItem(i));
}
return temp;
}
