hi,
Will there be a fix from nvaccess for this? Should I use ESR when 57 hits the air?

Hi,

As for that, it is due to the fact that Firefox is using multiple processes for accessibility routines, which impacts NVDA.

Cheers,

Joseph

There will be a problem when browsing through very dense web pages with lots of links and info.  I just tried  facebook.com, talksport.com, bbcNews.com, these pages are so sluggish that it would be better to use internet explorer instead.  Cheers!

Hi gene

 

I downloaded the 57 beta a little while ago and found the setting he was talking about. Mine was already unchecked. I downloaded the beta of 57 and i am just looking around now.

 

The menus are been spoken. The quick navigation keys seem to be working etc.

 

There is a little lag some times when you go to the menus and or left or right arrow. I was just having a look in the options section it looks like only 4 tabs now

 

I have read a couple of articles so far from our stuff website and gone back and forth between pages.

 

as mentioned there is a little lag at times seems no worser than 56 actually at a few times seemed quicker.

 

Now and again you have to refresh the page as like the page does not load and using the f5 key lets it load.

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
