 FF mobile has an additional "protection" against eavesdrop of
 accessibility events. It dispatches the events just if exploration by
 touch is enabled.

                     mEnabled = accessibilityManager.isEnabled() &&

 It means that the user must enabled it, manually. And when it is enabled,
 it changes the UI behavior, the user must double click to select form
 fields. Single clicks, normally, makes the system to read the element.

 I tested it using https://github.com/alper061/ScreenSpeak and TalkBack.
