After months of constant Thunderbird crashes and hundreds of crash reports, and as many attempts at trying to resolve the issue but without any resolution, I am now getting the following message when Thunderbird crashes:

Thunderbird had a problem and crashed. Unfortunately the crash reporter is unable to submit a report for this crash.

Details: Expected value at line 1 column 1

I have version 128.5.2esr installed, but the issues started well before this version you can see the information in the crash reports if you want to look at them. I have tried Troubleshooting Mode, and can confirm the issue persists. I have also noticed that the one IMAP account I have attempts to redownload all messages from the mail server - it never completes because Thunderbird always crashes first. Aside from the obvious request for troubleshooting suggestions on the primary crash issue, I have three additional questions:

1. Is there a way for me to isolate that IMAP account, in another profile or such, to see if that account or server is contributing to the issue?

2. How is the crash report interpreted - i.e. where do I look to see the actual cause of the crash? In the "Details" tab the CRASH REASON and CRASH ADDRESS are not very informative to the average user.

3. What is the best way to provide a list of crash reports - I've had nearly 30 over the past few days, and - literally - hundreds since the issue began in October (which did not appear to coincide with anything in particular - e.g. new hardware or software, or TB update. Is is acceptable to post a list in the body of this thread, or as a txt document, or .... ?

BTW, running this on a Windows 10 22H2 machine, i9-14900KS, 32Gb DDR5, previously nVidia Quadro P5000 now Intel Arc A770 Graphics. Yes, have tried rebuilding POP3 folders, and yes I have a backup of my profile, which is about 35Gb in size.

TIA

Hi Everybody All of my folders in Thunderbird have become subfolders, which is annoying, but worst than that, most of them don't have messages in them any more. What have I done, how can I undo it and find those messages? I hope someone can help. thanks Rose

Thunderbird won't remember where it was last time (windows 10 and 11). Every time I open it, it has shifted and resized a bit from the last time. It's not one monitor to another or even the other side of one screen, but it's always slightly higher or lower, slightly smaller or larger... It's just driving me nuts because everything else is perfectly positioned. Note that I am using fancy zones to do this placement, but everything else works fine.

The Inbox show have 1 message,but the dialog cant display message. when i use [search message] in inbox ,the message can display. Thanks,Have a good Day! Richard Lee

Five people at our company have a representative email address that can receive emails from each other, and each person also has a personal email address that they set up to receive emails from.

Emails received at the representative email address are received in the inbox of each of the five people.

However, on four PCs, only two weeks' worth of emails received at the representative email address are saved.

Emails from two weeks ago are automatically deleted.

They are not even in the trash.

All emails received at personal email addresses, even those from two weeks ago, remain there.

Also, on one PC, all emails received at the representative email address and those from two weeks ago remain there.

All PCs were set up on the same day and I think they have the same settings, so I'm wondering why this is happening.

I would appreciate it if you could tell me a solution.

Thank you in advance.

Dear community,

I have decided and will stick with Mozilla Thunderbird, with hopefully future support for important and established standards such as IMAP, Card DAV, Cal DAV and so on. Apart from the other free providers, I have also spent a long time studying the many options and settings of this client. Very few seem oversized or inappropriate. Very nice, minimalist design and functional! Some people should be ashamed of what they complain and demand. I am a big fan of my own domains and emails from established hosting platforms. Email is more important to me than social media and messaging apps. I really appreciate your work. This is not about annoying advertising and money, but about passion and commitment. You guys make me happy. Thank you.

Dear Thunderbird:

I have used Thunderbird for years. I click on Attach to add images to my email. To check the attachments, I would double click on each one and it would open in my Microsoft Photo Viewer for Windows. However, now instead of opening the image, I get Adobe Acrobat Reader Home page and no image.

Has something changed in Thunderbird ? Or is there a simple setting I can change with your coaching ?

Thank you for your help.

In Thunderbird I see two methods of accessing/editing SMTP settings for email accounts.

1. Using the "Outgoing Server (SMTP)" which displays all the email accounts in a list. You then select one and click "Edit" to view or edit it.

2. On each email account page there is an "Edit SMTP server" button. Click that to view or edit the SMTP settings for that account.

I'm seeing two problems:

1 - The settings made using #1 above don't carry over into what I see using #2 above.

2 - Using method #2 above, changing the SMTP settings for my newest email account also changes the settings (seen using #2 above) on one other email account. And vice-versa.

What could be causing this?

I reset my PC and saved the wrong profile path, so i cant restore my thunderbird profile the normal way. However, I exported the profile to my phone and the thunderbird android app, where it is still stored. Can I export my profile from the App to then import it on the PC version? thx for your help!

I changed computers and in order to make sure I could use TB on the new one, I updated the old computer from 120-something to 128.5.2, and then installed 128.5.2 on the new one as well. The transfer went okay - once I saw the video that explains how to do it - but when I sat down to write an R-T-L email, it didn't automatically R-T-L, and when I looked for the "switch-direction" button I was used to in the old TB, it wasn't there! I can write in Hebrew, (or Arabic), but I can't R-T-L the text. HELP? HELP! Thank you

I have banged and scratched my head raw over how to get Thunderbird to setup accounts for GMail and Yahoo, both of which require OAUTH2 authentication. When I attempt to do so, Thunderbird hangs for a long time, when trying to verify my login name and password, and finally comes back to tell me my login credentials were invalid. I am using the exact same login credentials that I use to log in to my accounts from a web browser, which works.

I have tried to follow the online help instructions at - https://support.google.com/mail/answer/7126229#zippy=%2Ci-cant-sign-in-to-my-email-client https://support.mozilla.org/en-US/kb/thunderbird-and-gmail

but no joy! I am using Thunderbird version 128.5.2esr (64-bit) running on Linux/OpenSuSE 15.6 with the KDE/Plasma/X11 desktop. I don't know what additional information to provide but will be glad to do so, just ask. Any kind gurus around that can help me get out of these dark woods and guide me towards the light? I am lost!

Thunderbird was open when my Ubuntu Unity 24.04.1 LTS system abruptly powered off. When I restarted the system, Thunderbird first downloaded a ton of duplicate Emails from pop.gmail.com. Once I cleared those out, Thunderbird now times out attempting to reconnect. I am running the .deb (not the snap) version of Thunderbird 128.5.2esr (64-bit). I'm sure something got corrupted and I'd like to get that straightened out. Thanks in advance.

By the way, I do have both the Cardbook and GCalTab addons which read my contacts and calendar entries from Google just fine. Only the Gmail portion is FUBAR.

I have several errors associated with the unified folders display. I have 6 email addresses coming in to Thunderbird. 3 are IMAP and 3 are POP. I have the POP addresses consolidated into the "Local" Folders Inbox, Sent, Trash etc. In the "All Folder" account views, the Local folder correctly displays one Inbox, one Sent, one Trash etc. The 3 POP emails accounts are being consolidated appropriately. However,in Unified folders, the Local folder as well as all of the individual POP addresses are now listed for the Inbox, Trash and Junk folders. There is now no consolidation.

Also, the Unified folders themselves are extremely slow in working. Accessing the properties for the Unified Inbox, Trash or Junk folders results in a long wait with Thunderbird entering a not responding state. Right click operations on the unified folders do not work at all. I cannot select properties, I cannot mark as read, empty or otherwise manipulate the folder. I must go to the individual accounts to manage any folder content. Which I would think makes the whole concept of Unified folders moot.

I am not at all certain what may be the root cause of this rather longstanding problem. I have deleted the smartfolders directory, have deleted the virtualfolders.dat and foldercache.json and foldertree.json files. Nothing seems to work.

Any suggestions?

I run Thunderbird, Thunderbird ESR, K-9 or Thunderbird. Windows 7, 10 and 11, Linux and Android 5.1 and 12.

My desktops all have a gmail and yahoo.co.uk email addresses. Each account is linked to there respective contacts server but all my contacts are in one gmail account which has lost most of the contacts in recent months, that is, only the contacts that I have used recently are still present. So I have been investigating the settings and adjusting in some cases.

Some instances all the account are still linked to the contacts servers. Other cases only some of the accounts are still linked and I want to re-establish the other accounts that have become local accounts, these still have my full complete address book.

Lastly between K9, thunderbird, contacts google I don't know what went wrong but I like advice on how to avoid the problem in future. In the meantime seasons greatings, no hurry my christmas messages will have to wait.

I setup my account it worked well, I changed my office365 password. I was prompted to login with Oauth2, and it worked. However, I can receive emails, but cannot send emails. I get a notice that my password is wrong when I come to send emails. It just happens because of the password change. No matter what I do I cannot find where the Oauth was saved for smtp. There seems to be a desync, where the password updated for the Incoming server, but never lets me or updates the Oauth for the smtp server. Any thoughts?

Deleting saved passwords, just gets me to do Oauth2 for the incoming, it never takes effect on the smtp server.

Using thunderbird to connect to the mail server outlook.office365.com with imap gives the message "user is authenticated but not connected" . I have 2 accounts on this server and one works fine and the other gives this message. This occurs on both Windows 10 and Windows 11. Latest version of Thunderbird is being used. Any help would be appreciated.

Many times when I am forwarding emails or copying and pasting text from an outside source, the spell check will choose a word like "isn't" and highlight "isn" as a misspelled word. This has happened with a number of different contractions.

Additionally, it will pick parts of an abbreviated name in someone's email address in the To: field as a mistake. I do not have the time or desire to constantly, go through a long email and choose 'add to dictionary' or click ignore. Why is it even looking at parts of a contraction, and it should be ignoring the To field altogether.

Is there something wrong with my version or is this how it operates? My TBird is up-to-date: 128.5.2esr (64-bit).
