 - The {{HTMLElement("input")}} element supports a new `mozactionhint` attribute, which lets you specify the label for the enter key on virtual keyboards.
 - {{HTMLElement("script")}} elements inside {{HTMLElement("iframe")}}, {{HTMLElement("noembed")}}, and {{HTMLElement("noframes")}} elements now get executed, which they weren't in previous versions of Firefox.
