Popup Url and Search Bar is a Firefox add-on, can hide the URL bar and search bar, create keyboard shortcuts for the urlbar and the searchbar. It makes them popup over the page content area and dragable. The default shortcut bindings are ctrl+L/alt+D for urlbar and ctrl+K for searchbar. You can move both bars to anywhere over the page content area by draging the bar icon(using left-click). And the positions for both bars can be remembered even though you re-start Firefox.
