Thunderbird Community Forum

As noted in my question something odd has appeared in my Thunderbird Email. Can someone help me get back to all English. I double checked my TB settings and it appears they are all set correctly.

Thanks, Brad

Hi there I tried many solutions that I found concerning body text not displayed. But hat no success. Let me describe in detail. From one day to the other the following happened. 1. Emails in the local folder stored on a NAS (for archive purposes) did no longer display the body text (from one day to the next) However I could still transfer them into the corresponding inbox and then read them. 2. Upon trying to change settings, reinstalling the newest version of Thunderbird and also an older version, the solution of putting the emails into the inbox and reading them or forwarding them to another account does no longer work What I tried:

      1. Repair the Folder:
      2. Rebuild the Global Database:
      3. Check for Add-on Conflicts:
      4. Verify Account Settings:
      5. Examine Local Folders Storage:

Now my knowledge is depleted and I am looking for help. Thanks in advance. nelexc

Since upgrade to 128.10.1esr, list of emails in local folders is visible, but cannot view email contents, cannot forward, cannot reply, cannot move, cannot delete.

IMAP folder functionality is all OK.

Occurs in both 64 bit and 32 bit versions of 128.10.1esr

After this occurred on 64 bit machine, we had 32 bit two machines running a previous version of Thunderbird that were still able to access (read, forward, delete, etc) emails in the same local folders (local folders are on network and accessible to 3 different computers).

After upgrading one of them, access to emails on local folders broke on that one, but still working on remaining machine running older version.

This means it is not corruption of local folders (e.g. folder repair and .msf deletion don't make any difference).

It seems to be a problem with this version since update.

How can this be fixed, do we need to wait for another update?

Hi,

I'm on a fresh Windows and the CPU usage is waaaaay too big. When TB is out of focus, it uses about 10% of my CPU. This can go up to 15% when the window is active. It's not doing anything, not downloading or compacting or anything.

Thanks !

I've moved thunderbird between windows 10 computers several times without any issues in the past, but I'm having problems now.

My old PC is running windows 10 with the most up to date TB. New machine has windows 11.

In the past, it was just a case of installing TB on the new machine and replacing the profile folder there with the one from the old machine.

Now when I do this I get "your thunderbird profile could not be loaded. It may be missing or inaccessible"

Ay help with this woould be much appreciated

Thanx for initial reply to my help request ...

My problem with Thunderbird downloading my Yahoo.com e-mails continue.

I've changed Yahoo.com passwords in the past with no problems. Thunderbird seems to have changed & become more complicated. I can't find the app password Generator for Thunderbird, but I'm able to see my Yahoo Password & the Oauth2 security protocol etc

So how in the heck can I get Thunderbird to work properly? And download my my messages into TB as it has done for years.

Hello, I tried following the steps on [https://support.mozilla.org/en-US/kb/.../moving-thunderbird-data-to-a-new-computer]. However, I currently have a flatpak installation where I land in a folder which also has executable among other files (?). I do not see the usually named profile folder and therefore cannot copy it to my new computer. Do you know how I can move in this case? Thanks

I have read your explanation on how to move TB to another PC. BUT this explanation assumes there is an App Data folder on the new PC. In Windows 11, there is no App Data folder and there appears to be no Profiles folder.

I had a tech guy move TB to the new PC, and I can now get and receive emails there. He could also copy over my Sent and Address folders, but NOT my older emails or, more importantly, my Calendar. How do I get TB to run on a Windows 11 PC like it does on my old Windows 10?

Thank you. Jim Bachman

I changed my Google account password just today. I have used Thunderbird on PC for Gmail without issues for years. I went into Thunderbird Saved Passwords and changed the appropriate line to the new Gmail password. I restarted Thunderbird and tried to send a test e-mail. I kept getting "Login to account Google Mail failed" with a box of 3 options, Retry, Enter New Password or Cancel. When I click on either Retry or Enter New Password, it doesn't give me a chance to enter a password and goes immediately into the same "Login to account Google Mail failed" box with the 3 options. I searched and read the support and one of the option is to remove the line from Saved Passwords and re-create it. I did that and tried to send another test e-mail. Now I'm still not getting a chance to enter a new password. I keep getting the box with the 3 options which doesn't allow me to enter a new password. There isn't a new entry in the Saved Passwords.

Strange thing is Thunderbird is receiving new e-mails fine. I'm just not able to send.

Thanks.

Hello team,

While drafting this message, If i want to put the next word

on another line, there is a default space that gets created. This is quite annoying.

So I draft the mail on Notepad++ and no more line breaks like we see here. Is that something I can do in Thunderbird do in setttings? I am not able to find how?

Regards, Karan

Note: I have attached a snaoshot drafting the same note as above on the Thunderbird client to show my issue.

Is there a way to locate the empty "Inbox" In the TB folders and delete it from there?

I can't see them in any sub, and "Inbox.sbd" is empty 🤷

( TB folders are located on a local Disk, managed by Dropbox. Also doing Cloud BKP)

For a week, I have not been able to send any emails through Thunderbird.

This is the only day that I have been able to delve further into the problem.

If I send an email, this is the response that I get after sending. Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I have contacted my main provider and they have been useless. I contacted my secondary provider and they sent me what the settings should be. I checked their info against mine and everything is correct.

I prefer Mozilla products over all others and I wish to get this corrected sooner later, I have two assignments to send over the weekend.

I would rather being doing something else that trying to figure out this problem.

I should be celebrating or mourning the passing of my wife 3 years ago, than trying to figure out what is wrong.

One thing I did do was to go to the Mozilla website and download Thunderbird again in case there was a conflict somewhere in the system.

Thanking you in advance. K

I would like to be able to click the little fire icon on an email in my "list of emails" window to Mark as Spam, then have Thunderbird automatically move it to my Bulk folder after that.

I looked to see if I could set up a filter to do that, but don't see "Marked as Spam" as one of the selection criteria.

Is there a setting to accomplish what I'm looking for?

Hi! I am trying to rid myself of Microsoft Outlook and am transitioning to Thunderbird. I will speak in Outlook terms... I want to do the same with Thunderbird. My Outlook activity is saved on the server and on my hard drive as .pst files. I periodically do a backup up by simply copying them to another drive. I would like to do the same in Thunderbird but don't know what the file name, extention or folder name/locaton is.

What is the file name and extention for the Thunderbird version of these files and what folder on my hard drive can I find them? A search on C:/ for .mbox returns nothing. Your insights will be welcomed!

Jim

I'm using Thunderbird 102.15.1 on kubuntu. With previous versions I could set up an automatic filter to move emails to defined folders depending on various criteria. How do I do this with this version? Thanks Hugh Grant

Hello there,

I am using Thunderbird 128.11.1esr on macOS Ventura 13.7.6 (OCLP) and would like to have all my accounts displayed in one unified inbox:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-16-23-42-32-0314df.png

In the past all my accounts relied on pop3, but now of them changed to imap only, which now shows up like this:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-16-23-43-14-1d6721.png

Is there a way for me to have just one inbox folder? I set it up like this ages ago but can't recall which steps need to be taken to receive the desired view.

If I choose View > Folders > Unified folders I get this:

Thanks in advance!

Transfer Thunderbird email and data to another computer. I have attempted to transfer my email data from / to Windows 10 computers. The instructions seem straightforward but so far I have not been able to bring up the "new" computer after copying / transferring the data. I have a Linux laptop I could transfer to, but the versions don't match and I'm not sure it would work anyway. Any help or direction to instructions (I thought I have looked everywhere) would be great. Thanks
