easy to use and understand Rated 5 out of 5 stars

Works precisely as described, easy to use.

The code is rather simple,

function oldbarStartup(event)
{
var urlbar = document.getElementById("urlbar");
urlbar.setAttribute("autocompletepopup", "PopupAutoComplete");
}
window.addEventListener("load", oldbarStartup, false);

Thanks. Keep up the good work.
