Hi Joseph


Why would they put in such a setting?


I am guessing if checked it would speed up the browser for the sighted but be use less if checked for us.

Hi,

You need to keep this checkbox unchecked. And I haven’t found an easy way to reverse this at the moment (Alt+T, O won’t work here).

Cheers,

Joseph

How do you disable it if you can't work with menus and all the other structures you discussed?  Can you use the command alt t then o to get into the options dialog and can it be worked with?  Are you saying that we need to check this check box in the options dialog?

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
