So if you leave that checkbox unchecked, how accessible is
Firefox Quantum then?

Well, the tests ended so fast…
The following is a community-based
advisory that is mandatory for you all to listen up and
If Firefox 57 is set to prevent
accessibility services, you won’t be able to use Firefox at
all. The following NVDA features will fail:
- Browse mode and focus mode
- Web browser features such as
elements list and first letter navigation commands
- Object navigation and review
- OCR functionality
ADVISORY: when Firefox 57 lands, DO NOT
check “prevent accessibility services” checkbox in Firefox
options. By default, this checkbox is unchecked.
Technical: NVDA uses mixture of code
injection and accessibility API routines to access Firefox.
However, when accessibility services are turned off, Firefox
enters a mode where the UI and browse mode functionality
will not work with screen readers. This means no
announcements regarding menu bar, no toolbar navigation
feedback, no feedback when you type into address bar, no
browse mode and so on. The only way to restore it so far is
disabling the checkbox described above until NVDA finds a
way to interact with Firefox Quantum.
