Re: Unknown Content in Firefox

It’ll say “unknown” when you switch to Firefox, and I found out the hard way when I tried it on a VM.
One way to help narrow down the issue: Tim, did your colleague say anything about accessing the menu bar (Alt key)? If your colleague says NVDA reads menus, then I’d give weight to Gene’s diagnosis.

Subject: Re: [nvda] Unknown Content in Firefox
If accessibility is turned off, nothing will be spoken as I recall when the program is opened. Not menus, not anything when a page loads, nothing but the title bar. Since nothing is stated in the original message about an inability to see the interface, the accessibility access being turned off appears to be unlikely.

Another possibility: it is Firefox 57, correct? If so, is accessibility support turned off from Firefox itself?
I use the same configuration – NVDA with Firefox and with the last Firefox upgrade it all blew up…mainly because our Deque add ons didn’t work with the newest version of Firefox. Back it up a couple of versions and you should be okay.

I have a coworker who needs to be able to use NVDA and Firefox—we use it as part of our accessibility testing. Everyone else seems to be able to use NVDA 2017.3 (or 2017.4) with Firefox 57 with no problems.
However, every time he tries to use NVDA 2017.4 with Firefox 57, NVDA says the content of the page is “unknown”. He says it works ok in Chrome and IE 11. He was also having the problem with NVDA 2017.3.
So far, we have tried de-installing NVDA and re-installing it as well as de-installing Firefox and re-installing it. Neither action fixed the problem.
Has anyone else run into this problem and been able to resolve it? If not, does anyone have any suggestions for what we might try next?
