## Gecko-specific notes

• 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 `subscriptshift` and `superscriptshift` attributes has been fixed (see bug 827713 for details).

• `<msub>` (Subscript)
• `<msup>` (Superscript)
• `<mmultiscripts>` (Prescripts and tensor indices)
