I updated to 155.0.1 via the update modal yesterday, on MacOS Tahoe, and it didn't restart as normal. The main message pane was blank with "No Message Found" (screenshot attached).

I tried installing a fresh 155.0 over, that did not work; but, a restore of the prior app from my Time Machine did work -- that is, the application not the user profile data.

I just thought this was strange; never ran into it.

If there is an issue and I can help test it usefully, I happy to do so (I have backups! LOL).

Thunderbird has been working well, but all of a sudden it stopped sending my emails from aol accounts. I have tried many internet solutions and nothing is working.

This afternoon, without any warning, all my mail in every folder could not be displayed. This is the second time this has happened in the last month and a half. I have two mail accounts - one that goes through Yahoo and the other Gmail. No mail is displayed in either account.

When I run Thunderbird in troubleshooting mode, the mail does display. I then disabled the few addons that I use but that didn't make any difference. When not in troubleshooting mode, no mail is displayed.

Of course, there's "troubleshooting information" but that's way too technical for me to get anything out of it.

I've been a Thunderbird user for over 20 years and I would like to keep using it but this performance is discouraging.

What do I need to do to get past this issue? I'm assuming I'll be able to read an email response by using troubleshooting mode.

Thanks.

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

Thunderbird is regularly (at least once a week at random times) forgetting all my passwords. I have tried all the suggestions I can find (deleting various system files etc) and nothing changes. The passwords work for several days, but eventually when I start Thunderbird it has lost all my passwords. This is something that started about two or three months ago; before that, I never had a problem.

P.S. Yes, I select "use password manager" (or whatever it's called) every time I have to put in the passwords.

I have 3 email accounts which i unified. when log in I get prompted to enter password for all three accounts which I do, then I get prompted again to enter the password to all Password Manager to save my passwords which I do not want and therefore I uncheck it for all three; I then get prompted again for all three which I enter password, then I get imap login error on my main account which I click cancel a few times before it goes away,

I use Thunderbird portable. How do I fix this issue. it should be that one enters the password for each account once not three to four times. I do not want to use Password Manager to Save my accounts.

Also if ever I have to change password how do I do that? thank for your help.

I have the portable version, download from portable apps website.

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

I have over 200 email accounts in Thunderbird, and I am getting constant pop-up error messages that say: "Не удалось открыть индексный файл для 'Входящие на [email]'. Возможно, произошла ошибка на диске или полный путь превышает допустимую длину."

I don't need help fixing the emails themselves, but I need to permanently disable these pop-up alert windows because I will soon have over 2000 accounts and I don't want 2000 errors popping up.

I am using the latest version of Thunderbird. I have tried looking for "about:config" or the "Navigation Toolbar" to change the settings to "false", but my interface is heavily customized and I cannot find the menu or the address bar. I need a step-by-step guide on how to disable these error alerts, preferably using the Windows Registry or a configuration file if the menu is hidden.

I would like to setup Thunderbird as my email client.My email service is provided by Godaddy with an Outlook account. When I am at the incoming server settings, it has my domain name, not smtp.office365.com which I tried with both authentication options (below) and with my domain name, the protocol was IMAP. I changed the port from 143 to 993. I changed security from Autodetect to SSL/TLS. For authentication, there was not an OAuth2 option, I tried Autodetect and Normal password, neither worked. And I used my domain email password. with using my domain name, it came back with an error an suffixed my domain name with :110. It stated that this was not the correct domain and there was a security issue. It is not clear how I should progress.

Years ago when I was using Thunderbird there was "fix" for the Advance to next message pop-up, which appears when you press N or P to move to the next/previous message, and that message is on another account. If I remember correctly I think the fix was going into the "debug list" where you could change individual settings if you knew the name of the setting, and set it to off.

Anyway I couldn't find that list at all in the current version (probably a good thing). Is there a setting somewhere or fix where I can turn off this popup?

Just started Thunderbird and all my accounts and mails are gone. All empty. I tried to import from default: C:\Users\Korisnik\AppData\Roaming\Thunderbird\Profiles\fjv3tdcd.default and now I have mails until 2025, all from year 2026 is gone. What to do???? please answer to [redacted email from community support forum]

I've been using TB for years and all has been working well. But now I have no idea what is going on.

When I try to download new email from my Yahoo account (using pop3) it tells me that it is downloading 1 or 25 (say) and none get downloaded.

Then I delete some emails in TB and a little while later those deleted emails get downloaded again but none of the latest emails. Even if I logiin to Yahoo and delete those emails, TB seems to manage to download them again. How?

If I delete the first email it should download sometimes the rest will download but not always. Sometimes when I update to the latest version of TB emails start downloading.

I have tried to doing a repair on the Inbox but this seems to make no difference.

I've no idea what to try. Anyone got any advice/suggestions?

Also, how do I get from the Beta version of TB to the stable version? I don't even remember choosing to use the Beta versions.

Lastly, I often get pop-up messages saying that folders cannot be compacted because something is using those folders. I've never understood why TB puts out this message. Why does it not just compact the folders when it has done whatever it is doing? Is there a way of stopping these messages and finding out what is using the folders?

Since changing my gmail accounts settings in thunderbird under Synchronization and storage so as not to store a local copy of emails. Thunderbird, after a while, is no longer able to authenticate to imap.gmail.com. If i delete the associated oauth2 saved passwords, restart and regrant access. Thunderbird is ok for a couple of hours but then fails again later. Thunderbird ran fine for a couple of days before i changed the synchronization settings.

Any ideas on how to eliminate this annoyance?

When replying to an email or sending a new mail I get the message :- An error occurred while sending mail. Server responded : You need to authenticate when sending mail from (ip address) Please check "message Recipient" and try again. How do I authenticate ? Thanks140.7.1

These are some things I have explored:

   • It is happening whether I look at emails in Thunderbird or through Gmail on Google Chrome
   • Even if I clickndrag them from deleted to inbox they fall back into deleted.
   • I’ve tried gmail/settings/all settings/filters and there aren’t any
   • I’ve tried gmail/settings/all settings/forwarding and there aren’t any
   • If I access Gmail via Microsoft Edge, the emails stay in Inbox
   • I’ve looked at various things in Thunderbird and unticked something in ‘When New emails arrive’ because I thought that might work.  

It started happening about a week ago.

The authentication is not working with many of the directions I have found online. I create an app password from logging into AOL website and have no where to put the password. If the password request is made is does not accept the password. Things aren't where the direction indicate. Getting the connection to request the password sometimes works but no password works. I tried the app password and rejected and multiple other password don't work.

Based on the latest version of Thunderbird where things seem to be changed, how to specifically set up this new authentication.

It's driving me crazy,

Thanks...Carl

As the title says, over the last two days Thunderbird won't do SMTP authentication to Outlook. It has worked happily for years and nothing at my end has changed.

I've the latest version of Thunderbird - 140.15.0esr (64-bit) - and this is Windows 11. It works happily from the Outlook desktop so the password is correct.

The authentication method is OAth2 and connection security is STARTTLS. Server is smtp.office365.com and port 587.

Anyone else having issues? Presumably MS have changed something (again)

Has anyone any suggestions on how to resolve?

After swapping to The Bat some years ago I decided to come back to Thunderbird again. So I installed Thunderbird 155.0.1 (64-bit) on my Windows 11 PC, and gradually re-created and connected the the accounts I had on the back. I also installed the ImportExportTools NG addon, then exported my emails from The Bat to Thunderbird. So far so good. However for some reason I created an account twice. There are both for the same GMX account, but one is POP and the other is iMAP. This mistake probably happened after a long session of setting things up and I just forgot about the first account.

I looked through the Thunderbird help and the answer most given was to the Thunderbird menu, select Account Settings, swap to the account you want to delete, and then press the large red DELETE BUTTON on the top level of its settings (next to the DEFAULT button). I've tried this and it doesn't work. There's no confirmation dialog (which is what I was expecting) and if I close and reboot Thunderbird the account is still there.

How can this be fixed?
