re :I have no Mozilla Crash Reports, because it doesn't ever shows up.

Check you have this option enabled.

• Thunderbird > Preferences > Advanced > 'Data Choices' tab

Crash reporter:

• select checkbox: 'Enable Crash reporter'
• click on 'OK'

When it happens again......... Generated Crash reports are here: Help > TRoubleshooting Information Scroll down to Crash Reports section. Copy the crash report id and paste into this question in forum.

Hello,

Thanks for your reply.

The Crash Reporter was disabled, so I enabled it.

Today I had another crash, but the Crash Reporter hasn't showed up. No crash reports were generated under Troubleshooting Information.

After I force the quit, it opens the Mac Os Problem Report window. Does it contain useful information?

Is there anything else I can try?

I also tried to:

- Delete Thunderbird - Delete the Profile folder - Reinstall Thunderbird from scratch

Have you tried safe mode?

On windows the left shift key being held invokes it if it is held when starting Thunderbird.

often it is add-ons and graphics hardware that causes crashes. The sort of hard crash that appear before the Mozilla crash reporter can kick in are most often graphics or hardware issues. Eeen to the point of hard disk errors at the hardware level.

Safe mode disables a lot of the higher level hardware acceleration that goes with graphics, so try that first.

Next check the hard disk for errors The steps shown in 1 here should do it. https://www.anysoftwaretools.com/check-mac-hard-drive-health/

This should eliminate errors in allocations that can generate invalid program files and invalid data.

Hi,

I tried with safe mode, and I also checked for disk errors, but unfortunately Thunderbird is still crashing.

It doesn't happen every time I send a mail, so it's not easy to reproduce.

But it still happens.

Any other suggestions?

Thanks, Roberto

Does it happen with version 68? https://www.thunderbird.net/en-US/

I didn't know there was a new release, thank you!

I'll give it a try.

Unfortunately after installing version 68 Thunderbird lost italian localization, and it seems there's no way to get it back.

However, if it works, I will keep it this way!

I'll let you know.

Thank you, Roberto

Hello,

I had no luck, Thunderbird is still crashing with version 68.

I have the crash report, if needed.

Thanks, Roberto

Please post the crash 'report id' number.

Hello,

I have no report id. As said before, unfortunately Mozilla Crash Report is not working: even if i enabled it, is not showing up after the crash event.

However, I managed to save a text document with the crash report information from Mac, you can download from it here:

I hope it's useful, thank you very much.

I'd say this is Bug 1381485 - Hangs frequently while sending imap mail while copying message to imap Sent folder on Mac. - displaying the progress bar. No problem if Sent is set to local folder. Deadlock on CGLClearDrawable.

Still waiting for action there. Until then, you might try setting your Sent folder to be under Local Folders

Hello,

Thanks a lot for the information. It seems my problem exactly.

Does that mean that the Sent folder will not be accessible from other devices? If so, I can't go that way.

Thank you, Roberto

I have exactly the same problem. It's been many updates, and still happening. isn't there any way that Mozilla can resolve this bug? seems like a major thing for mac users, and I can't believe there are no more Mac users complaining about this problem. i'm using version 60.9.0 with iOS Catalina. And this continues to be an issue. Thanks!

re : try setting your Sent folder to be under Local Folders - Does that mean that the Sent folder will not be accessible from other devices?

Yes. It will only be in Thunderbird profile on your computer. But you could back it up to OneDrive or usb for travel purposes.
