I can't find any reference for them supporting it on mobile, and it doesn't work in either on my phone (Android 7.0, for what it's worth). In fact, in Chrome it even fails to display the "not supported" message.
Besides that, I would rather complain that Apple is using an obscure format than complain that Mozilla and Google don't support an obscure format.
EDIT: sorry, it seems mobile Chrome is supposed to work, but it just... doesn't. Still don't see any reference for firefox, though.
