The newest browser versions directly support 'border-radius' without the vendor specific -moz or -webkit prefixes. For support of all versions include both in such a way that the newer browsers see 'border-radius' first.
FWIW some elements resist curving attempts on the newer versions of IE (IE 7 + 8) and Opera (below 10.50), 'Fieldset' comes to mind. The Fieldset's 'legend' ends up being inside the 'box' rather than it's normal place along the top border of the box.
