When using FFOS2.0, if press volume button & menu frequently，the system will turn on screen reader.But now the system will have some problem.And if disable this feature will have no other feature risk，we hope to disable screen reader. And hope you can provide a plan to disable it.
I think you can remove screen reader code in system app , then you won't have screen reader function. But you may also also need to remove accessibility settings section in settings app [2-7], so it won't show up when user enter settings app.  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/system/js/accessibility.js  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/settings/index.html#L157  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/settings/index.html#L335-L336  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/settings/js/accessibility.js  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/settings/elements/accessibility.html  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/settings/elements/developer.html#L173-L178  https://github.com/mozilla-b2g/gaia/blob/v2.0m/apps/settings/elements/root.html#L171-L173
