This sounds to me like the longstanding problem that some programs, when you uninstall them, unregister some.dll files.  NVDA has a utility to correct the problem.  Open the menu with NVDA key n.  Find and open the tools submenu.  Find and run the com registry fixing tool.  That may not be the exact name but its close enough that you will know it.  The tool reregisters the .dll files, if they have become unregistered.

This also happened to me and I dealt with it by  installing  Waterfox at that time as a slimmed down version of FireFox with at the time better accessibility.

I have now pretty much moved to using Brave full time now so I am not quite sure of the full status of Waterfox. I relaunched it just now and it appears to be still OK.

Subject: [nvda] NVDA and Firefox

Hi Everyone

I use Windows 7, NVDA 2019.3.1 and Firefox 68.5.0ESR. It works fine on
one machine.

I have just installed NVDA on another Windows 7 machine and, when I load
Firefox, it says the title of the page and then keeps saying "Unknown".
This machine had a previous version of Firefox which was updated today
to 68.5.0ESR.
I created a portable version of NVDA using the first machine and
installed it on the second one.

Can anyone advise me how to make it work on the second machine?

Thanks
