Thunderbird Community Forum

I'm running Thunderbird 138.0.3 (release update channel). I had an update in the past few days and now it is having a problem. Thunderbird starts OK but it I use another program for several minutes when I go back to Thunderbird its window is not visible. Looking at my system monitor Thunderbird is using a lot of CPU. The only way I can proceed is to kill Thunderbird from the system monitor. No crash report is generated. Running in safe mode does not help.

If I run Thunderbird from a terminal I get: $ thunderbird [64132] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM ATTENTION: default value of option mesa_glthread overridden by environment.

This seems pertinent as it it to do with graphics but the web seems to suggest it in not important.

I have copied the Troubleshooting information to a text file and so can share it but it is quite large does not seem appropriate to include it here.

Any help gratefully received.

I am no longer receiving calendar notifications for events which are entered as "all day" events on my Google calendar.

I had a similar problem about three years ago when I wasn't receiving notifications for ANY events on my Google calendar. I attempted to solve this problem in a similar fashion by uninstalling/reinstalling Thunderbird then disconnect/reconnecting Google Calendar as discussed in the following link, but the All Day events' notifications still are not appearing.

As a debugging step/temporary solution (so I don't miss notifications), I have integrated my Google Calendar with Outlook, and am receiving notifications correctly with that app, so the problem doesn't appear to be on the Google end.

Hello folks, This has been a normal part of using Thunderbird for years, One of my Gmail accounts takes forever to synchronize... Eight or ten minutes... Strangely today, it's two of my other Gmail accounts that are taking very long.... Thanks ! Craig in Seattle

Hi, I recently had an office location change and post that in my office laptop, Thunderbird cannot authenticate with outlook and collect mails from it. IT team tried syncing the password from their end, and we tried a million other things like checking server settings in Thunderbird etc, but nothing is working. It just says "connecting to outlook.office365.com...." and is stuck there.

I'm using Proton VPN. I have the split tunneling set to allow non-VPN connection for thunderbird.exe . It doesn't work. I have a different app that needs split tunneling and it works fine, so it's not the way Proton VPN handles split tunneling. I'm wondering whether I should use a different exe as the split-tunneled one. I see 8 other exe's in the same folder. Perhaps one of these is the one to set-up for split tunneling. BTW I had exactly the same problem when I was using Nord VPN.

Thanks,

Tom

On Windows 10, address book sync with the server Radicale works fine from TB to Radicale, but TB does not receive address changes from Radicale. (Sync of calendars and tasks works perfectly to and from Radicale.)

I tried to find a log file for this, but failed.

Help greatly appreciated!

Crashes upon opening thunderbird almost immediatly, then I don't get any error reports even thought it says that it has successfully generated one. anyone know what the issue could be?

Cheers.

Today my email suddenly will not load onto my computer but I can view the email in the web browser. The error says The certificate is not valid for server. I did not set this email up and need step by step instructions.

For some reason, I am getting message that the Certificate for server is not valid (etc.). I can not get or send my emails as of this morning. Is there something I can do to resolve this issue?
