Re: Mandatory advisory: when Firefox 57 lands, do NOT check "prevent accessibility services" checkbox


 

Why would you want to disable accessability at all.

Hi all,

Well, the tests ended so fast.


The following is a community-based advisory that is mandatory for you all to
listen up and follow:


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 modes
* 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.


Cheers,

Joseph
