Help/Troubleshooting, under Crash Reports, see if there are recent reports and post the URL here.

In the meantime, start Windows in safe mode with networking and see if TB still crashes.

The latest of many (one for every time I have used, and then attempted to close, Thunderbird since "updating" from v60.something)- https://crash-stats.mozilla.com/report/index/26338d5b-16e4-439b-8ca7-344dc0200117

Safe mode makes no difference to this.

with the update process failing every time.

same problem for me and i can t see my mail but thubderbird does'nt crash but it no work

The crash report links to this Bugzilla report that refers to the wetransfer component in TB. I don't see a specific solution there, but if you have wetransfer added as a filelink provider in Tools/Options/Attachments/Outgoing, Remove it and see if that stops the crashes.

I don't.

The bug report which is associated with https://bugzilla.mozilla.org/show_bug.cgi?id=1559448 is difficult to follow, but perhaps that the crash is not dependent on a specific addon.

If you can reliably reproduce this issue, please post in https://bugzilla.mozilla.org/show_bug.cgi?id=1559448

Following that link leads me to find that to comment there requires setting up still another account, which is just another added annoyance, considering that there would be no point. There is nothing further to add. It's very simple, from my end.

I can reliably reproduce this issue, and defining it is just as simple as I already said.

The steps go like this:

1. open Thunderbird 2. close Thunderbird 3. Thunderbird disappears from the screen, and in Windows Task Manager, it disappears from the list of running applications, but checking the processes list, it's still there, for at least a couple of minutes, until it disappears from there and the Crash Reporter pops up.

This has happened every single time. Since I updated to v68, Thunderbird has never closed properly, has crashed every single time.

I only got it to install by uninstalling the previous version, and installing by running the install executable downloaded because the built in update routine of Thunderbird could never successfully update, first to 68.3.1, then to 68.4.1.

Restarting in Safe Mode makes no difference.

Trying to remove the only add-on (the Lightning calendar, which is essential) makes no difference.

Simply starting the program, doing nothing at all, and then closing it makes it crash EVERY SINGLE TIME.

At some point I need to learn my lesson, go back to find some reasonably stable old version, and STAY THERE, because for a few years now, a formerly great program has just gotten worse, and worse and worse, and worse...

Your frustration is understandable. It may be no consolation for your situation, but to add some perspective by my calculation of the crash statistics this crash affects 0.001% of users. It has never been found through any testing, and because of the apparently low incidence it has only just recently come to light. Hopefully the information you posted will be of some help - thank you for posting it.

Just to be clear, it only crashes on shutdown, correct? In other words, it doesn't affect your ability to use the program?

It's only on shutdown. As far as I can see so far, there is nothing else. (I say that, when, really, for a long time now, Thunderbird has gotten worse and worse in terms of frequent hangs, with it shown as "not responding", for long chunks of time. Sometimes it's after I, you know, DO SOMETHING, such as typing a few letters into an email composition, or, maybe, click on an email to read... sometimes, occasionally, there seems to be no reason at all that I can see.)

But, aside from all that, the only malfunction I can find so far that discounts the now NORMAL malfunctions is crashing when I close the program.

I went and found the install exe in my files and reinstalled v60.3.0 a little while ago, so, now, I can actually run and close Thunderbird.

What AV software do you run?

What AV software do you run?

I've added information to https://bugzilla.mozilla.org/show_bug.cgi?id=1559448

Just to get this in here, I saw there was a new version (68.4.2), proceeded to update, and... as before. Start, shut down, crash.

BTW, regarding the AV question- irrelevant. The antivirus software I use, I use to conduct scans. I run nothing resident in memory to tangle up the works. If something new comes up, I scan.

It looks like, once again, I will be doing like I did before, hauling out the install executable for v60-whatever it was, and carrying on.

Do you have "Expunge inbox on exit" enabled in Thunderbird server settings?

I see no such item under server settings.

In that case, you are seeing POP next to "server type" rather than IMAP as in this screen shot?

Yes, incoming mail is a POP server.

I see your copy of Windows is out of support. Perhaps it need to be updated. However please go to the troubleshooting information on the help menu and scroll down to the heading Extensions.

Use your mouse to drag over and highlight the list and include the Information in the Security software section. Press CTrl+C to copy the selected text and paste it into a reply on the forum.

Willing to try older betas to find where the crashing starts? That will help us determine what code patch affected thunderbird.

I'd start with https://ftp.mozilla.org/pub/thunderbird/releases/64.0b4/win32/en-US/

Backup your thunderbird profile data first https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data
