Thunderbird コミュニティフォーラム

I have TB 128.5.1esr configured to check MS Outlook mail using the Owl for Exchange extension. To resolve an issue where Outlook misfile emails, I deactivated all my local TB mail filters and replaced them with Outlook rules. Ever since, I've had trouble with displaying messages.

All my messages appear as usual in the main the main window but often when I click on one to read it the message pane is blank. The content sometimes reappears if I select and deselect the message a few times or if I use the keyboard shortcuts to start a reply. The affected messages seem random.

I've tried repairing all my folders and I've rebuilt the mail index by deleting the sqlite file from my profile but it keeps happening. I can't figure out why changing message filtering from TB to Outlook would matter but am not sure how to troubleshoot further. Has anyone else had this problem?

thanks,

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?

I have been using Thunderbird for over ten years and today is the first time I have ever received error messages, no less two back to back that are preventing me from downloading new messages. I know that I have sufficient disk space and don't know how to correct the rest of the errors in the 2 attached images of the error mesages.

Any help will be appreciated. Thank you.

As indicated, when checking messages, indicator shows that imap is being queried but it takes forever to load the messages. This may have been happening in beta 133.xx too.

"..... because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." Hi, I have two gmail accounts and I've been having difficulty compacting folders for the last couple of days. Both of them are IMAP accounts, and I typically keep them clean and prefer to save my emails in local folders. I have tried deleting the email accounts on thunderbird and re-adding them. It worked for about 24 hours and I am getting the same message again. Running as administrator has not solved the problem. Thanks for the help, Ron

I've got a weird display problem that started yesterday. As I scroll along my messages list, characters start blanking. Where the blanking occurs changes as I scroll.

Screen shot attached.

A brief run with Thunderbird in safe mode doesn't seem to have this problem, but I have zero extensions installed.

H/W: Ryzen 7 7700, RX7600XT, 32 GB and 2TB SSD for C drive.

Thunderbird is the only APP I have noticed this on.

Performance was already poor in v115, but has gotten much worse since upgrading to 128.5. This is a documented bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1906482 Are there any known workarounds? If not, how can I downgrade with losing all of my settings? I have 7 e-mail accounts and a few calendar accounts set up. This took a lot of time, since several of them require app-specific passwords. Thunderbird complains if I try to open a profile from a newer version in an older version of the software. How can I do this safely?

Just started using Thunderbird Mobile. On my desktop, I have checked the leave messages on server until I delete them box. However, if I bring in email on the mobile app, it deletes everything from the server. Is there any way around this?

Firefox/Mozilla/T/Bird: When I open my inbox my emails showup. However when I click on the individual messages some open "normally" and are immediately accessible while others showup with msg notification on a black background with identifying subject but I am unable to open the content of the msg, When I click again it again the screen goes blank and back to mozilla. When I try to "Delete" I have to click on "Inbox" again and all of the unaccessible/unreadable msgs are deleted. Help Thanks Patrick

After I upgraded my system to Kubuntu 24.04 thunderbird started eating CPU (150+% CPU usage according to htop). Because I couldn't tell if the culprit was the new KDE or the old profile, I tried to create a new profile, blow away the KDE config, etc. I also tried downloading the latest version of thunderbird from the website. Nothing helped.

I was able to replicate this problem using the in-memory, fresh KDE.

To replicate: Create Kubuntu 24.04 install USB. Boot from this USB. When asked to install or try, select "Try Kubuntu".

Start Thunderbird.

When prompted to create an account, select cancel. Go into settings, to the bottom, and select Maildir for file storage. Quit thunderbird, and start it again. Create account (select configure manually, enter the information for imap and smtp host, STARTTLS, detect authentication. My username does not contain an @, if that makes a difference). Select "Re-test"

Try to read mail. You will quickly notice that Thunderbird is consuming > 100% CPU, and UI is non-responsive.

Restarting thunderbird does not help.

netstat -tupane shows one or two connections to my imap server port 143, but wireshark doesn't show any traffic on port 143

Not that I think it matters (since I can't get Thunderbird to start seriously downloading from the server) but I have a big ( >100G) Maildir behind my courier server.

Note that I see this problem both with the version on Kubuntu 24.04 install USB, and the latest version downloaded from the thunderbird website.
