+<p>[1] A partir do Gecko 17 (Firefox 17 / Thunderbird 17 / SeaMonkey 2.14) até o Gecko 26 (Firefox 26 / Thunderbird 26 / SeaMonkey 2.23 / Firefox OS 1.2) a propriedade <code>iterator</code> era usada (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=907077">bug 907077</a>), e a partir do Gecko 27 até o Gecko 35 o placeholder <code>"@@iterator"</code> era usado. No Gecko 36 (Firefox 36 / Thunderbird 36 / SeaMonkey 2.33), o <a href="https://developer.mozilla.org/pt-BR/docs/Web/JavaScript/Reference/Global_Objects/Symbol">símbolo</a> <code>@@iterator</code> foi implementado (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=918828">bug 918828</a>).</p>
