Rendering in your browser: $X_{1}$

<math>

  <msub>
    <mi>X</mi>
    <mn>1</mn>
  </msub>

</math>

BCD tables only load in the browser

Starting with Gecko 26.0 (Firefox 26 / Thunderbird 26 / SeaMonkey 2.23 / Firefox OS 1.2) it is no longer possible to use <none /> as a child element. The rendering has been made more consistent with equivalent configurations of <msup> and <mmultiscripts> and a bug with an incorrect application of the superscriptshift attribute has been fixed (see バグ 827713 for details).
