NVDA Is Very Sluggish in Thunderbird

Rich DeSteno

I am using NVDA Version 2020.3 on a Windows 10 computer.  I use Thunderbird Version 78, which I believe is the current version. Recently, NVDA has become very sluggish in Thunderbird.  Reaction to key strokes often takes up to several seconds.  This makes it very difficult to read or write emails.  What could be the problem here?  Nothing has changed with my system.
