Hi, I have been using TB for many years, when suddenly 4 days ago ( Feb. 1st.) it started as a brand new install, asking to set up a new account, I got no previous warnings or had other issues.

Since then I have done several attempts to get it connected with my profile, among others: - Everything from this article https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data - Importing the Profile from Functions > Import > "Import from another Thunderbird installation" - Reinstalling TB ( without removing the profile)

All of it with no succes, there is no accounts, and no mails, only some empty local folders so I'm running out of good ideas, and I really hope you can help!

BTW, somehow the addressbook has content, as the only thing.

Thanks Best regards Preben

Some Junk Mail (so far, only from my Outlook mail account) is appearing in my Inbox. This mail has a yellow banner at the top stating "Thunderbird thinks this message is Junk mail". Also on this banner is a button marked "Not Junk", that allows me to tell Thunderbird that it is not Junk. At the very top of the message (as with all messages) is a button marked "Junk", which in this case is "greyed out" and so won't work, although this button is not greyed out for messages that are not thought to be Junk!. This seems counter intuitive to me. Thunderbird is allowing some messages into the Inbox which it thinks are Junk, but disables the button that allows me to confirm it! I know that I can still mark the message as Junk by using the individual menu for the message (3 vertical dots), but why disallow the obvious "quick action" button?

I inadvertently deleted a mail sub folder named Shopping Oder Confirmations I found the folder in my acronis backup and copied it to my desktop I then pasted it in to the profile window of thunderbird in hopes that when i restarted it would show up in my mail folders which it did not I can send you screen shots of the different windows where I dropped the folder Can you help please?! There is tons of information in these folders I reference often. Thank you! BTW I did just make a donation :)

Bonjour Depuis qlqs temps j'ai un dossier Envoyé et Sent message Je souhaite supprimer le dossier Sent message et je n'y arrive pas Comment faire ? Salutations

I have been using Thunderbird for quite a few years and all of the sudden I have been receiving the message below yesterday and it's still continuing with this error:

Connection to sever imap.gmail.com timed out

I have not changed any settings Tried all the different suggestions found online (checking port numbers, taking off anti virus, worked in troubleshoot mode, even un-installed Thunderbird and then re-installed, etc)

The problem is still happening. Not sure if anything was changed on the back end of Thunderbird but I cannot receive or send emails at this point.

Please advise. Thanks!

My old computer crashed and I have gotten a new computer. It's a Dell All-in-One. So anyway my question is how do I get my email to cross over to my new computer? Also we had LocalTel for a short time and my email and information went through them. My email address was Lorirn@ifiber.tv, they closed the ifiber.tv email system but was still managing it. So when my computer crashed somehow they knew about it and cancelled my email and closed everything. So now I can't get my emails that I had, which was a lot of them. Some were very important to me. I am in a very bad situation. I am hoping that you can help me somehow. I did try your transfer Thunderbird Profile Files and I don't think that I did that right. I have downloaded Thunderbird to my new computer. So I need lots of help from you if at all possible. I am hoping with fingers crossed. I have had to change my email to Lorirn5755@gmail.com, let me know if more info is needed.

Thanx in advance Lori Bolin

When I open an email that contains a thread, each response (or reply) shows up in its own window. This results in LOTS of email windows on the screen, and I have to fish around to find the one I want to see. Then I have to close all of them one at a time. How can I change this so the email thread is in one continuous window?

I have found a complete folder with subfolders in my Trash at last three or four times now, and I did not move it there. The folders are still in Local Folders but they are empty and I have to move everything back. Why is this happening? Just in the last six months has this occurred.

I have Thunderbird 142-esr on a Windows 11 computer with two users in separate Windows users account. The second user (my wife) suddenly had her gmail login stop working on TB, even though it continued working on all other devices. The symptom was that the inbox would hang trying to log on to gmail, although no error messages appeared.

My account worked normally throughout this time.

After trying less destructive fixes such as closing the application, logging off, and restarting Windows, I guessed there was an issue with her account, possibly a corrupted file. So I deleted her gmail account. When I tried to create a new account, TB accepted her credentials and the Google login came up. I successfully authenticated to Google, but installation failed when I returned to the TB new account screen. After a long wait, TB issued an error message saying the password or user name was bad.

I did two tests to isolate the problem. First, I attempted to install my wife's gmail account in my Windows TB instance. That failed in the same way. Second, I attempted to install my gmail account on her Windows instance. That worked. I concluded there was nothing wrong with her instance of TB. I thought it might be an issue with her password, although Google has never asked her to change it, and there haven't been issues logging on outside of TB. Her password did not meet Google's current requirements, so I changed it to 12 characters, mixture of upper/lower case, numerals, and special characters. That worked.

Unfortunately, during the process, I lost her settings, and it took a while to recover them from backup media.

I'm posting this more to ask if others have experienced such a problem than as a request for help, as I think the underlying issue is now resolved. Because it may be some kind of malignant interaction between TB and gmail, I thought it might be worth reporting as well.

While checking mail in my inbox, I opened, then deleted a message (message 1). As has been happening lately, there was a significant pause between my hitting delete and the mesage going away. Then I opened another message (message 2), and I found that it had the header for message 2 displayed in the inbox, but showed the text of message 1 when opened. Scrambled messages and headers could be a big problem.

I logged onto the mail server (gmail) directly. It showed me message 2 with the correct header, and message 1 was in trash.

To fix the problem, I deleted message 2 on the server, and waited for it to vanish from the headers in my Thunderbird inbox. Then, I copied it back from trash on the server. After it downloaded to Thunderbird, everything was fine, but I wanted to alert you to the issue. Something evidently can go awry on TB's end to scramble headers and messages, and that is scary.

Running TB 147.0.1 with gmail(imap) as the mail server. I have posted twice in the past week about issues with gmail, and I am suspecting something going on at that end. My TB installation is brand new since then; the problems with logging on and staying connected that I reported only went away when I removed .esr, rebooted, and did a clean install of TB.

Please advise if this is a known problem, and if there are settings I can tweak to prevent recurrence.

when I view the saved passwords, the saved logins window does not work properly. I cannot drag the borders left or right to view whole information such as passwords or provider. The borders just refuse to move. I therefore can only view partial information under any heading. Please help if possible. Thank you.

Update: Apologies, seems it was my mistake. While setting up the signature in the first place I *did* pick up a named anchor from a template <a name="_MailAutoSig">. It was buried in the generated HTML, and I have now found and removed it. Problem, such as it was, now solved.

Is there any way either to remove the yellow anchor symbol which Thunderbird inserts in front of my signature, or to tell the client not to display the symbol? I didn't put one in the HTML signature that I use. There's no "remove named anchor" command. It isn't related to the double -- marker, which I've already removed using config. I have no use for anchors, which for me are simply a visual distraction.

Thunderbird is so good in many ways (calendar synch is great - one of my major bugbears with Outlook - also recipient privacy when sending out group invitations) and it can be quite frustrating in some others (e.g. unwanted features that I've had to dig around in config in order to turn off)

Thanks everyone :-)

I recently re-installed Win 11 with the help of a Dell tool. During the re-install all of my data files were kept, but not the applications. I've re-installed Thunderbird and it works fine. However, I've noticed that my address book is empty. I've found abook.sqlite through the Profile Folder, so I know the file exists, but how do I connect it to the Address Book link in Tools? Thanks Sam

Thunderbird has become crazy slow. 5-10 minutes to display an email. It's not my email server because my phone connects to and displays email fast. I have been through all the advice that I can find and cleared, checked, disabled everything that might slow it down. Still crazy slow. If I kill it and restart, I get about 3-4 minutes of reasonable performance and then it just stops. Latest Release Version V147.0.1.

i have a fast machine with 32Gb memory only 60% used, everything else runs fast

I don't want to junk Thunderbird, but it's unusable.

Help!

TO WHOM IT MAY CONCERN

I cannot add my work email, jdehal@cesconsult.com, to Thunderbird. I receive the error message enclosed. My password and username is correctly being entered, I have done this several times but receive the same error message.

Please help !

Sincerely, Jay Dehal

This just started 4 or 5 days ago ( 2026.1.23 ish). I did not update TB nor make any changes to the account in question (that I'm aware of). The errors show up every few minutes, with a 'beep' sound and notification pop-up showing up each time - is very annoying.

I was running v145 when it started. I saw there was an update to 147 and installed that; same issue. I restarted TB into Troubleshooting mode and am still getting the error.

This is running on MacOS 15.7.3. Hardware is MacMini (2024) with Apple M4 chip.

Generally I still seem able to received & send emails.

I opened Activity Manager and Error Console. Error console doesn't seem to have much (using 'Multiprocess', with Errors, Warnings, Logs, Debug enabled). Activity manager shows things such as:

<my account name>

   Connection to server outlook.office365.com was interrupted.    09:49
   Failed to connect to server outlook.office365.com.    09:52
   Authentication failure while connecting to server outlook.office365.com.    09:58
   Authentication failure while connecting to server outlook.office365.com.    10:03
   Connection to server outlook.office365.com was interrupted.    10:10
   Connection to server outlook.office365.com was interrupted.    10:14
   Connection to server outlook.office365.com was interrupted.    10:20

There was an error or log entry that I was able to find a few days ago that made me think it was Calendar related, but now I'm not finding that message.

Sending of password for user (name) did not succeed. Mail server mail.skymesh.com.au responded: [AUTH] Authentication failed. this is the message I get and then no new mail comes, I can sign in to my skymesh account

I have recently installed 140.7.1esr (64-bit) on Windows 11

1. It keeps asking for my account password, I always check the box for saving to the password manager, with no effect, I still have to type it in every single time. (I did set up pwd manager and I do have a master pwd)

2. Initially I had Thunderbird pick up my Gmail account as well, but it stopped picking up my Gmail for some reason. So I completely deleted my Gmail account in Thunderbird. yet it persistently asks for access to Gmail every 15 minutes. (I get a notification from Gmail saying that Tbird is asking for access to Gmail). The Gmail account no longer exists in Tbird, does not show up in the menu, and it does not download anything from Gmail if I give it permissions.

One of my 2 Tbird accounts will download a new message but not display the contents. In the inbox list the message remains bolded, and clicking on it won't display the contents or unbold it. Any suggestions? Tkans, Alan

My Thunderbird will not connect to the Comcast/Xfinity email account with the same settings that Outlook connected to and downloaded all my emails and my inbox structure. I believe this is either a battle between Comcast and Thunderbird or a big glitch in this application, My Gmail, Outlook365, work fine in Thunderbird, not Comcast. This started about a week ago. Has anyone found a solution?
