I recently upgraded from Thunderbird 116 to 128 on Kubuntu 22.04, since then it has crashed at least once every day.

For some reason it is unable to send a crash report, instead I get the attached window pop up.

I recently changed my password to a passphrase. Thunderbird 115.16 ER Linux could not/would not handle it. By changing to a password based on the passphrase, Thunderbird sometimes works fine.

In Thunderbird version 132.0.1 (32-bit) running in Windows 10 version 22H2 (Build 19045.5131), when composing a message, I have no option to "Add to dictionary" when I right-click on a word with a wavy red line under it. How do I make this option available? Thank you.

Bonjour. Thunderbird version 128.4.3esr (64 bits) - Windows 11 Professionnel 24H2 Build 26100.2314 Depuis quelques temps, les icones "Cardbook" et "Raccourci Google Task" apparaissent en double dans la barre d'espaces. L'activation/désactivation des 2 extensions ne changent rien. Avez-vous une explication ? Cordialement

Around 3:15 pm yesterday, I stopped getting emails from Outlook (Hotmail). I can send emails out. When I check activity manager, I see: Connection to server outlook.office365.com timed out Why? I Did not change anything. My settings are: Server Type: POP Mail Server Server Name: outlook.office365.com Port: 995 Connection Security: SSL/TLS Authentication Method: OAuth2

The theme keeps resetting randomly to "dark" - although it shows that the "light" theme is enabled - it still switches to "dark", i.e. the interface is the dark mode. I then have to Disable and Enable the Light Mode for it to be Light mode again. But, then even within a few minutes, while I might be doing something else - when I go to Thunderbird, it has switched to Dark mode again .... This is FRUSTRATING.

I have updated my Thunderbird and now I couldn't find my inbox, sent, and trash features.

Attached is the current state.

I am using MacOS 14.6.1

Any advise on how to fix this would be appreciated.

Thank you!

My wife is having a severe problem with Thunderbird. Here is some detail: With a "fresh" invocation of Thunderbird, all incoming messages are received, in two different email accounts. Outgoing messages can be sent. After a while (can be two days, can be a week or more), the following error message is received when sending an outgoing message: Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent... Once this error message happens, all incoming mail (for both email accounts) stops. If she then terminates Thunderbird, and restarts it, she will normally get an error message during the restart, which states that "Thunderbird is already running, but is not responding." If she accepts to terminate this non-responding process, then the next restart of Thunderbird is successful, and she can receive (and send) messages again. The workaround (as noted in another posting) to save the sent message to a local folder allows the current outgoing message to be saved, and she can then copy the saved message to the proper "Sent" folder after she restarts Thunderbird. However, this is very annoying---having to save locally and then recopy---especially if there are several messages in progress when the failure occurs. In addition, it does not "solve" the problem; a restart is still necessary. A similar error message is presented sometimes, when Thunderbird is saving a draft message. It speaks of "a copy was not placed in your draft folder" (or something similar; I don't remember the exact details). When this error message appears, Thunderbird goes into the same state as above: no incoming messages are received, and a Thunderbird restart is the only fix. Please note that this problem has been showing up for at least the last six to eight months. It seems to be getting more frequent, to the point where my wife now explicitly restarts Thunderbird every couple of days. Her environment: Windows 10 Enterprise; Dell tower; Thunderbird 128.4.2esr

I am also running Thunderbird on my laptop. I have six email accounts. I have never seen the above error message in relation to sending messages, although I have seen it concerning the saving of drafts. However, I have never seen it prevent the receipt of incoming messages, the way my wife has. My environment: Windows 10 enterprise; Lenovo laptop; Thunderbird 115.3.1

If there is a way to gather more extensive logs from my wife's computer, to aid in solving this problem, I will be happy to help. Please tell me what to do, or put me in contact with appropriate persons.

Hi, my PC runs windows 10 and thunderbird loads but then that's it there is next to zero operation, no get new messages, just locked🤔 All settings are the same as K9 on my phone and email works there. I uninstalled and reinstalled thunderbird but that altered nothing. Antivirus and security are normal and trouble shooting says nup so I'm lost🤷 I have a modest knowledge in regards to this and all ' advice ' online has had zero impact. Any help much appreciated thanks Mark B

TB 115.10.1 I have several accounts which all work fine, however when I go in to Troubleshooting information and open my profile folder it is only 2Gb in size. All my mail accounts and associated files are located in a separate 92Gb profile directory with the same profile name (I know where it is). I want to consolidate all this information in to a single profile directory on another faster SSD on my machine.

Creating a new profile mapped solely to a copy of the 92Gb profile folder copied to the new SSD doesn't work -no email accounts display.

If I then add only the set of files in the main directory of my 2Gb profile in to the newly located copy of the 92Gb profile on the faster SSD all works fine, however if I add a new mail subfolder and I can see the name of that new sub folder is located back in the original 92Gb profile on the old hard drive.

How do I fix this? The working 2Gb profile folder is mapping all my mail and accounts to a different location and I can't find out where TB gets the information telling it where the main mail store is. I want to move this main mail store in to the location of my working profile and move the lot to the faster SSD. Thanks for any suggestions.

I have Thunderbird 128.4.2 (32 bit) on Windows 10 Home (64 bit). I want to add a second email account. To do this, I used File> New> Email Account. I entered the email address and password. TB found and entered a server configuration. The new email address appears in the Folder List but has only an Inbox folder after it. The other folders (Sent, Junk, Trash) are missing. Test messages show the new address in TB will send a message correctly except it hangs trying to save the sent message. The new address is unable to receive a message. Please advise how to get the new email account (outlook.com) set up in Thunderbird. Thank you.

I am trying to download emails in a Gmail label and send them to Dropbox. So I downloaded a label with Takeout. That got me a zip file in (unreadable) Mbox format. I translated the Mbox file with Thunderbird. That got me readable text files in Thunderbird. Then I downloaded the files to the desktop. That got me unreadable eml format files. How do I get readable files that can transfer to Dropbox? Thanks

Followed directions on moving profile to new computer. All accounts and messages moved over with no problem. New laptop is Dell Precision i9 ultra with 2tb ssd + 1 tb ssd secondary, 64gb ram running under Win 11 Pro. I have 5 accounts mostly gmail and hotmail with about 18gb of emails (including attachments). Ran fine with older laptop running Win 10 even with cad, tbird and streaming video at the same time.

Tbird is slow running by itself but if I open Rhinoceros 3D cad program, then open Tbird to read an email it becomes really slow, lag, stutter and affects performance of entire system. Tried numerous fixes and rebuilding index helped quite a bit, but when I use my main program (Rhino 3D) then use tbird it still slows dramatically.

Any ideas appreciated :-)

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.

I've been using Thunderbird for years and never had any major problems until a few days ago. But ever since you automatically installed Version 128.4.2esr on my HP desktop running Windows 11, all I can get from Thunderbird is a blank screen unless I go into Troubleshoot mode. Subsequent automatic installation of Version 128.4.3esr did not help.

Send / Receive died - it was working yesterday & is still working on my laptop I cannot see what's wrong & also as far as I can see the IMAP & SMTP settings are the same on both machines
