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!

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
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

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.
