Hmm, I'm not sure what version of Thunderbird I'm running. It was 
updated within the last couple of weeks, and Help > About says I'm up to 
date though the version number it gives seems to be 45.8something.


anyway, I'm not having the problem you describe, but I have had it in 
the past: Jaws says, "Blank," or nothing at all as I arrow up and down 
the list of messages. I can tab from this blankness to the From field, 
etc., and though this works fine, it's really annoying and surprisingly 
time consuming. I routinely go through lots of email, and having to tab 
to the different fields to know which message I'm on slows things down. 
I seem to remember that the message list works fine when you are 
arrowing through search results.


My experience is that this is a Jaws thing. NVDA works fine, and in 
Windows 8 and above, Narrator works fine too. Btw, I think I remember 
that I can read the message body with Narrator only in Windows 10 
Anniversary and above, but I digress. In some cases, Jaws just magically 
starts or stops reading the Thunderbird message list for a few days here 
and there. In other cases, Jaws starts and stops working as Thunderbird 
gets updated.


I've never found any solution other than switching to NVDA when working 
with email.
