<p>[1] Implemented in {{bug("556743")}}.</p>

<p>[2] The <code>files</code> property was made settable in Firefox 57 ({{bug(1384030)}}).</p>

<p>[3] In Firefox 56, the implementation has been updated so that the <code>formAction</code> property returns the correct form submission URL, as per spec, when the associated <code>&lt;input&gt;</code> is being used to submit a form ({{bug(1366361)}}).</p>
