21.3 TB 140.7.1 esr
Not sure if this is a Mint or Thunderbird question.
A couple of times after starting TB it threw up a message that it hadn't been able to connect to a mail or news server. Fine. But on the Thunderbird tab in the taskbar
(panel) there is a red circle with a 1 in it. I assume that is referring to a message of some sort. But where is it and how do I read it? The 1 in the red circle remained
after I'd read and closed the message that TB showed at the start.
Mint's logs show only one reference to TB and that is when it was started.

You set a "max connection limit" per server. The default
may be two connections. These connections would run on
their own thread. One connection can attempt to connect,
and fail. It can print "I have failed" on the screen.
Meanwhile, the connection limit is not exceeded, so a
second thread runs. It could print "I have succeeded"
but instead, it just gets your email :-)
Any time you watch the status line on that software, it
is bouncing around like a hula dancer. It's not doing
that for fun, it's multiple threads messing with the
display. That's why it's such a God awful mess.
What software are you referring to? TB itself? I rarely see much on the status line except when I first start TB, manually check for new
messages, or click on a message to download it.
You could set the max connection limit to one thread if you want.
Imagine how sane the status indicator will be. The
order of progression in the left column, might actually appear
linear. Like you were using someone elses client.
After a few days without anything appearing, the TB tab finally showed a number a few minutes ago. I was able to get a cropped screenshot of it: <https://ibb.co/zWpWR2Wk>
When I clicked on the tab the number immediately disappeared. I checked
my email but there were *no* new messages in any of the four mail
inboxes I have.
There were some new messages on the two news servers I use, but there
have been new messages for several days without the TB tab showing a number.

It just appeared again after a "The connection was reset" box appeared. I think there was a fleeting box which appeared earlier today. That must be responsible for the number in the tab. I've just noticed that the tab for this new post message now also has a white No.1 in a red circle, as does the main TB tab.
So does it represent an error message has appeared? If so, does that message reside anywhere in TB's logs once it has disappeared from the screen?

OK, what facility does the Linux platform have for Notifications ?
And if one exists, did you turn Notifications off, forcing the icon
to do the job with the "1" on it ?

That's how to do it if you use Cinnamon, anyway.

Try turning that ON, so the Thunderbird Notification will cause a popup of some sort.
At a guess, you would still get an icon with a "1", but you should also get
a more-informative dialog from the Notification.
Actually, I think I saw a Notification in my test VM, but that's
a VM with its own email server inside, and not appropriate for your situation. But I think when my test email server wasn't reachable,
there was a Notification about it. Likely a TB140 or so.

"Well, in Mint Xfce there's a bell icon in the system tray by default

of the notifications, also some control over which apps can show notifications - eg,
I long ago stopped volume changes from popping up and clogging the log).
No idea for Cinnamon or MATE.

I've always had notifications enabled as I find them useful. However,
I'll disable them for a week or so to see if the TB tab number
disappears too. I guess that I could ask a question in the LM forum to
see if anyone recognises a TB tab with a number in it.

I seem to remember there's a icon of some sort which appears in the
panel when there's a notification (eg an update or upgrade to mint itself).
