Steps to reproduce:

This can only be reproduced on a small amount of machines running Windows 10 Creaters Update.
While NVDA is running:

  • Start Firefox and navigate a page with NVDA browse mode
  • Restart NVDA
  • Move back to Firefox and try and navigate the page.

Browse mode will not be available due to NVDA not being able to queryService to IAccessibleApplication to fetch the Gecko version.

#7207 is possibly related, though we don't have enough technical info there to be sure.

Note that #5758 has similar symptoms, but is very different technically and can be worked around. It'd be good if those of you who believe you are experiencing this can do the following:

  1. Switch to another application that isn't a Mozilla application. You may need to start another application if you don't have another open.
  2. Restart NVDA.
  3. Now switch back to the Mozilla application.

If you're experiencing #5758, everything will now work as expected. If you're experiencing this new issue (#7269), nothing will fix things except restarting the Mozilla app.

@michaelDCurran, as discussed, we should log CoRegisterPSClsid failures as errors to help diagnose issues like this.

confirmed with NVDA 2017.3 and firefox 55..0.3. I have been experiencing this for a while, and our Arabic speaking users confirm this as well.
