My Thunderbird updated to Version 128.6.1esr. Now my Lightning calendar will not display. Toolbar View Calendar is grayed out. Lightning does not display in the list of add ons or extensions.

Attempting this does not result in a context menu value of Reset:

This may happen if the update of the add-on is stuck. Don't worry about your calendar data, it is left untouched and will be available again if you follow these steps to restore Lightning:

   Go to the Advanced section of Thunderbird Settings and click on Config Editor...
   Copy or start typing extensions.installedDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103} into the search box
   When extensions.installedDistroAddon... is listed in the preferences list, right-click on it and choose Reset from the context menu - the preference now isn't bold anymore and its value is empty.

I use Thunderbird to read newsgroup messages. A couple of days ago I selected download 500 new messages. Instead of downloading new messages it downloaded a bunch of old messages from last year. Many of these old messages would not open to read, I would just get an error message when I clicked on them. This morning I sorted all of the messages by date then began to delete all messages from 2024. When I loaded up the newsgroup the folder was empty except for one message thread from yesterday, but the message count said there were several hundred unread messages in the group. I tried various trouble shooting solutions like clearing the cache and starting in trouble shooting mode. Nothing worked, but when I restarted Thunderbird it was now completely empty with no messages. I have tried to download new messages several times, but nothing new will download.

How can I restore Thunderbird and get it to download messages again?

If I have to reinstall, is there a way to do that keeps my history? I have years of sent messages, that I want to retain.

Here is my problem still. I have to close and reopen Thunderbird at times to get my emails. Sometimes the emails can be 2 hours old. I have checked with Xfinity/Comcast and they said it is a Thunderbird problem. I have asked this question before and got no help. What can be done so I get my emails everytime Thunderbird is supposedly checking for emails? I am using Port 993 and IMAP. Should things change at all? Thank you.

Global search provides a single general text input from which to search. Near useless. I typed in a date, result includes hundreds of message, mostly having a few digits of the date somewhere in the msg body. F1 (help) is not context aware, so rather than focused help, that might provide some hints how to craft a detailed search from a single control, it takes us to the home page for documentation.

Also: seems this is clearly not the forum to get anything done, as my prior inquiry is now archived. https://support.mozilla.org/en-US/questions/1353744#answer-1450482

Thunderbird on Linux, 128.6.0esr (64-bit) Compose new message, add an addressee, Right-click the addressee: context-menu offers: edit, delete, cut, copy, select, move. Choose COPY. Paste works nowhere. Data apparently not copied.

When I have written all my serverfacts and pressed the button "test again" I will get a green sign about found serverfacts. When I press the "ready"-button, I will get information that it is wrong, because "incoming server is already there", and then I cánt go on. What to do?

Hi all,

Notice that any search via email address or key word in upper search box for emails in 2025 returns nothing. 2024 and past emails in search are there. Rebuild the Global Database https://support.mozilla.org/en-US/kb/rebuilding-global-database and deleted global-messages-db.sqlite as instructed.

Problem not solved and global-messages-db.sqlite was not recreated in the profiles folder. Just took a global-messages-db.sqlite from a back up and put it in profiles to see if this helps. Also repairing one of my accounts to see if that helps.

Anyone know what is going on? I see several other posts about folks having similar problems in search and indexing. Running window 11 and TB 128.6.0esr (64-bit).

Also notice 2 stable extension are now non functional.

It seems like it may be possible to add "List View" to my Thunderbird calendar view selection options ( currently only: Day, Week, Multiweek, Month). "List View" is my preferred view in Outlook and Google calendars. I read that the "Lightning" extension needs to be installed on Thunderbird to allow List type calendar entry viewing. Lightening added nifty color coding options, but I still don't see a way to show my calendar entries in List View. I'm still a bit of a novice on Thunderbird controls and it seems like I may be overlooking something. Would anyone be good enough to offer a little help?

The dropdown folder list in Thunderbird used to close after dropping an email into the sub-folder, does anyone know if a setting has changed during any recent updates as I have to now manually close each sub-folder?

Hi,

I run my own mail server using Dovecot with the Virtual Mailbox feature to run some server side searches.

The folders contain the email that matches the criteria as expected but the message list (e.g. flagged email) does refresh (either waiting or clicking the Get Messages button) when a message is unflagged in this example until I restart the client. I am using the option "INDEX=MEMORY" which is meant to allow for this.

The issue does not occur with Thunderbird on Android, only my Desktop client on Linux.

Anyone have any suggestions?

Thanks,

Adam

I was using Thunderbird and changed to Outlook. Big mistake. I have now switched back to Thunderbird. I have Outlook emails in the .msg format. Is there any way to import these files into Thunderbird?

I could really benefit from some advice on the best way to proceed. Should I extend the date? And what are the ramifications of doing so? Should I add a new key? Should be publish the public key on a keyserver?

I am unable to send email from only one account in my T-Bird. I consistently receive the attached rejection. I have worked with provider and using alternative email I can send fine. Thus it appears the issue is with T-bird.. and only associated with one address... Help??

I am experiencing an issue with my email inbox in outlook account. Incoming emails are not appearing in the inbox as expected. However, when I use the "*" search function, I can find and access the emails. Could you please assist me in resolving this issue? Thank you for your support!

Hello, My system is ubuntu 24.04.1 Suddenly my Thunderbird no longer show inline and not even HTML code for incomming mails, just straight text. Some weeks ago everything worked fine. Of cause I have tried to tune in TB settings and the konto-specific part in TB, but nothing seems to help... I have tried a antivirus scan of the whole system with clamscan but no virus was found. Can someone out there give me a clue what to do..? Probably there is a very straight way, but I can't see it. Regards/LÖ

Hi I am using the latest version of Thunderbird.

I have an extensive archive of historic emails organised by past year which have been exported to local folders on my PC. In the past a search for old email content, for example from a specific individual, has brought up a list of all the emails in the Thunderbird account both stored in the Thunderbird folder hierarchy and also in the offline files and short extracts of these have been shown. Clicking on one of these has always recovered the full email body content for that specific email from wherever it was stored.

More recently I am now finding that the body of the emails in the offline folders are no longer shown and the only way I have been able to view that email is to note the date and then physically scroll through the offline folder for that date.

Please advise.

When retrieving/syncing mail from my imap account, the counter for incoming mail is always wrong, it says it is retrieving 4 out of 2 or 8 out of 1. Already tried the repair function, but that didn't help. Any ideas?

Thunderbird v. 115.14.0.
