Re: NVDA Web Browser Problem

Hi Quentin,


The problem was that I had uninstalled MathPlayer, and that removed a component NVDA uses for browsers.  Reinstalling MathPlayer restored that unknown component, and now NVDA works with Firefox and Internet Explorer.


JAWS apparently does not use this unknown component.  Note that this unknown component is not part of NVDA because uninstalling NVDA and reinstalling NVDA does not fix this problem.

Hi Louis,


Someone else reported a similar thing and noted the solution for them was to alt+tab away from Firefox and back.  It's not an ideal solution obviously, but I'd be curious to see if that helped.  That issue is:


There's another bug for a similar thing, saying "unknown" after reading the page title.  Often (in the case of this user), waiting a moment after that, NVDA would go on to read the page:


Finally, another problem that can cause this if it's happening in all browsers, is it could be a system component.  This thread has a number of ideas:


Finally, if you could get the log file to send to me that might help too.  Info on the log file available here:


Kind regards

Several weeks ago, my NVDA (version 16.4) was unable to access Firefox
(51.?).  When I opened a webpage, the arrow keys just said unknown when I
used them.  I uninstalled NVDA and Firefox and re-installed both.  I am now
on NVDA 17.1), and I have the same issue.

Any suggestions would be appreciated.
