MathML Accessibility in Mozilla

This table below provides a list of MathML constructions and how they are read in Mozilla applications for various platforms:

  • Windows: MathML support is provided by NVDA, which actually delegates math reading to the proprietary MathPlayer plugin. We started exposing generic accessible objects for MathML in bug¬†920547 and so these can be retrieved by NVDA starting with Gecko 27.0 (Firefox 27.0 / Thunderbird 27.0 / SeaMonkey 2.24). Mozilla and NVDA developers essentially do not have control on how mathematical formulas are read, please contact Design Science for any inquiries.
  • Mac: MathML support is provided by VoiceOver. In bug¬†1175269 and bug¬†1001641, we relied on the WebKit's NSAccessibility MathML tree to expose the main constructions. Hence basic support is available in Gecko 41.0 (Firefox 41.0 / Thunderbird 41.0 / SeaMonkey 2.38) and we are still trying to keep in sync with WebKit/VoiceOver. Note that VoiceOver is proprietary so we do not have control on Improvements to MathML accessibility in VoiceOver.
  • Linux: MathML support is provided by the development version of Orca. We try to keep in sync with WebKit/ATK/Orca developments. At the moment, it is recommended to use a Nightly build to ensure that the accessible tree expected by Orca is correctly exposed.
  • AccessFu: MathML support in Android and Firefox OS is currently being implemented in our AccessFu module and a patch is available on bug¬†1163374. The table gives the output in mode "utterance" and description spoken last. Note that this is still very experimental.
