If I have a password to sign into my Thunderbird emails, where do I find it. I haven't gotten this requirement in the past so where might I find it now and/or stop those messages?

Hello. Something strange happens in my emails. I read and/or delete an email and then at the bottom of any saved emails, the following shows up: no "from", no "subject" and no "recipient. It only shows 12/31/1969 5:00 pm. It is almost impossible to delete it. If I am lucky, it might finally disappear after closing Thunderbird and starting it again, several times. Becoming very much a nuisance. Thank you.

Hello,

I'm confused and slightly concerned.

Through no deliberate action by me, Thunderbird DOWNGRADED itself from the May 2026 standard release version to an AUGUST 2025 ESR(Extended Support Release) version.

UPDATE: the next application restart brought the ESR version up to date, but why was I forced onto the ESR version?!

What could have pissibly triggered this? I don't want or need ESR, and without knowing the cause, I have e no guarantee it won't happen again. Worst if all, everywhere I look, there is zero explanation for this. It appears to be fairly unprecedented.

My original installer for 102.15.1 was downloaded from the official Thunderbird site in 2025.

The sequence of events:

• I've had Thunderbird version 102.15.1 installed for awhile, but wasn't using it.
• Ysterday I opened it and connected an account.
• Today I noticed it hadn't auto-updated, so I went into the settings and clicked on the 'check for updates'.
• this brought it up to v115.10.1.
• Its success was demonstrated by me being sent to this URL after it opened: https://www.thunderbird.net/en-US/thu.../?locale=en-US&version=115.10.1&channel=release&oldversion=102.15.1(https://www.thunderbird.net/en-US/thunderbird/115.0/whatsnew/?locale=en-US&version=115.10.1&channel=release&oldversion=102.15.1)
• An hour later, I closed Thunderbird completely hoping it would fix a sync that appeared 'stuck'.
• When I re-opened Thunderbird, I saw the small "updating" window. It was pretty surprising since I had *just* updated.
• After Thunderbird opens, after this additional "update", the URL that I'm sent to is this: https://www.thunderbird.net/en-US/thu.../?locale=en-US&version=128.14.0&channel=esr&oldversion=115.18.0(https://www.thunderbird.net/en-US/thunderbird/128.0/whatsnew/?locale=en-US&version=128.14.0&channel=esr&oldversion=115.18.0)
• Thunderbird changed to a year old ESR version!

Hello,

After moving my Thunderbird profile to a new computer none of my accounts can authenticate. I followed the instructions here: Move Thunderbird data to a new computer, using "An alternative method for manual transfer between Windows 10 and Windows 11 computers." What explains the response in the attached image, "Something went wrong," and how can I fix it? Happens when I click "Next", the first step to log it.

I have a related problem with other accounts set up in the profile. This one is using Oauth2. I tried switching to password, and hand a similar problem. I tested the connection to the server in Settings for the account and it was successful. Same for the others. They all authenticate successfully on my old computer.

Thanks...

Gidday I have been using Thunderbird for sometime and recently had to re-install the program so now I have the latest version of it installed but the program isn't removing the emails from the server. I can't locate the "delete from server" setting anywhere in the options. I have searched everywhere for an answer here and on the iterweb so would appreciate if someone could provide help please. cheers col

I asked for help a few weeks ago, but all the suggestions failed to help. I still get the "Unable to connect' message as soon as I open up the Thunderbird mail app. I have tried to delete and reinstall my outlook email accounts, but no luck. It seems the problem is with Thunderbird inability to make the connection to any of my email accounts? On other platforms they work fine??? I don't know if Thunderbird updates are the problem. I even tried to delete and re-install Thunderbird, but nothing changed. I am about to abandon Thunderbird completely, unless someone knows how to get me connected to my outlook email! Thanks

I started setting up Thunderbird on May 8, after I got my new windows 11 computer. I added 6 of my most important email accounts (different providers). Today, I went through settings to make things better (I thought). Immediately after, all my email accounts (both current & previous messages started printing in plain text only. I tried to fix by going to view, message body as...simple text, restart, then back to original HTML. Then, restart again. All this to no avail. I am sure it is a setting because until today, all were in HTML.

Recently I posted about this problem here: https://support.mozilla.org/en-US/questions/1580858 In sum, I was having problems both in downloading messages from the Spectrum server and also with sending messages. I've attached screenshots of the error messages.

Matt and David kindly posted some helpful responses. The problem then seemed to spontaneously solve itself and I breathed a sigh of relief. Then a few days later it re-appeared.

This time it's not quite as bad in that I'll get the error messages but then usually a few minutes later I can download the messages or send an email. But it's still a real problem.

I called Spectrum again and this time the rep was adamant that if I can still use the Spectrum webmail feature (and I can), then it's not a Spectrum issue.

Last time Matt asked about my antivirus. I use Windows Defender (and occasionally do a manual scan with Malwarebytes free version), so if I understood him right, I should be OK as far as antivirus interference.

Matt also suggested I set TB so that I download messages at startup and every 15 minutes. I was set to every 10 minutes so I changed it to 15.

Matt said for me to check the Activity Manager. I've attached a screenshot of what that showed a few minutes ago. But I should note that this was after an error message displayed but my email downloaded anyway.

Finally, Matt said I should check the Error Console (Control + Shift +J). I've attached a screenshot of that. He also said I should use the trash can to clear it, so I did. He then said to press Shift + F5 to attempt to get my messages. But on my laptop, F5 just dims the display so no dice on that. But I have a second laptop and F5 is "neutral" on that one so I tried it there. I didn't get any new error message.

However, one of the screwy things is that sometimes I get all my messages as normal, but only after the "Can't connect to the server" message displays. And that's what happened with my second laptop above.

I hope I've provided better info. this time. And I hope you gents can help me with this mess.

Thanks,

Andrew

I had TB on my desktop for years and finally got it also synced to my phone. Then with a failure with Windows 11 had to wipe clean the desktop and start over. Cannot reinstall TB. I obviously have the correct e-mail and password as I was able to log into Mozilla and submit this question. I believe it is a problem with my user name and what is on my phone setup does not work with my desktop reinstallation.

From my local folder of emails in Thunderbird, I am able to extract to .CSV and see fields in Excel. While date and time and sender and receiver and subject fields work successfully I don't see the email body coming through. How do I achieve this please?

I managed to append switch values to get the Time field included as part of my extract but the email bogy, or even a truncated part of it eludes me. I understand that some of my email body fields are substantial but currently my repeated exports show nothing. Formats other than CSV would be welcome if they can solve my problem.

I get several daily email newsletters. I've set up a separate filter for each of the senders to move all these incoming newsletters to a local folder. I've attached a screenshot of one of the filters, but it's pretty straightforward: Move the email to the local folder, then stop filter execution.

Sometimes, but not always, it seems to run twice, and puts two copies of the newsletter into the local folder.

Note that the filter for "Morning Brew" and "Axios" have the stop execution step, while the filter for "1440" does not. The same behavior seems to happen (again, occasionally) for each filter, with or without the "stop execution".

I see another user having a similar issue here: Filter Issue

Any suggestions?

I have had to replace my laptop and am trying to set up my new one with an existing outlook account on the new device.

It is a Windows 11 device.

I have used the exact server settings etc from my old lap top for the outlook account but get a variety of error messages.

I have explored the use of the Account Hub and also switched that off/on. Same situation.

I attach five screen captured images so far. The first is the version of TB. The second is the window that appears when the account tries to connect and thirdly the small pop up that appears bottom right hand corner of laptop. The remaining two show the server settings and that they passed the connection test.

Other email accounts (gmail & yahoo) have both been set up on the new device and work well.

The account worked on the old laptop and continues to do so. I have set up the outlook account with, to the best of my knowledge, the same settings. The old lap top was a windows 10 device. The new laptop does not have a third party antivirus on it.

I am baffled as to what is happening and what I should do next. Any advice would be great.

Please inform me how I can mark senders in Thunderbird as not spam or is there a list of secure senders so their mails will not go to spam folder?

Best regards Magnus Arnason

I have had to buy a new desktop to get Windows 11.

I have installed Thunderbird, which I have used for many years, on the new computer. This version threads the incoming emails. I really hate my emails being threaded, it completely confuses me and prevents me doing what I have to do. I have not had this problem ever before. I have searched all the settings and not found any that will stop threading. Because the effect of threading seem permanent I now need all my emails reloaded to get rid of the effects threading.

I uninstalled Thunderbird and reinstalled hoping I could get a fresh start. I got the same old problem back again.

How can I get a version of Thunderbird that does not thread any of my emails ever?

And can I get all my existing emails re loaded?

May 25 2026. A few days ago, Thunderbird upgraded me to Release 151.0. I can no longer send or receive emails.

My wife has been upgraded to ESR 140.11.Oesr, and she has no problems.

I do not want to go through the tests of removing virus guard etc to try to make 151.0 work, so I would like to move to ESR 140.11, but cannot find online how to do that?

Please help.
