Thunderbird Support Forum

I have a new (one month old) Lenovo Yoga Book 9i with Win 11 and Thunderbird 115.7.0 (64-bit) installed, using Maildir folders. When opening another tab or window to view another folder (Right click, "Open in New Tab" or "Open in New Window"), the new tab or window opens in the new folder as it should. But so does the original tab/window! Opening further tabs and windows and switching between tabs/ windows and clicking on a new folder in any of the open tabs or windows results in all tabs and windows always being synchronized.  In other words, I cannot view two or more separate e-mail folders. They always all synchronize back to one folder. I can never have two different Thunderbird e-mail folders open at the same time!

Never had an issue like this before on other computers or earlier versions of Win/TB, including the same version of TB set up exactly the same way in Win 10 on another computer. As this is my only Win 11 machine, I cannot test it elsewhere. Has anyone else experienced this? Is it a problem with Win 11? Is there a solution, TB config setting perhaps?

For no particualr reason that I can see, all my email subfolders have disappeared today (15 Feb). they were OK yesterday. Very worrying as the filing systems separates and keeps all things I want to keep. Can you help please ? What have I done and can I restore them somehow ? Adrian Simmerson

Hi, I would like to eliminate table borders when I reply to a message, or when I forward it. I have tried putting some css code in UserContent.css. For example for "blockquote[type="cite"] table" I use !important. But the borders always remain. Which tag can I use to get border: none ?

How can I synchronize my address book across my devices running Thunderbird? I had an app called ZZAddresses that worked well for 10 years or so, until it quit. Does anybody know what happened to it, or what I can use instead? Is Tbird's promised synchronizer going to be real?

The inbox listings move once an email is selected. This began upon an upgrade to Debian 11 which included an upgrade to Thunderbird. I had the same issue with an upgrade to Antix 21 recently. That issue was resolved with another upgrade to Thunderbird about a week later.

I receive gmail using Thunderbird version 115.7.0

When I open an email from another gmail account with image attachment, it only shows the file name. Example 'image.jpg' but not download or open option for the file.

Problem solved when I changed Message Body from 'Original HTML' to 'Plain Text'.

It's this normal? Is it a problem caused by the sender? Or it there a better way I can handle this at my end?

Dear Mozilla Team,

using Thunderbird I encountered a new problem regarding my Microsoft live.com account. I've had problems logging in, I'm asked for a new password. I've seen that this here seems to be the problem (and solution): https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

I've then tried to follow the directions given in the article. However, I cannot change my outgoing smtp settings to Oauth2 (it only gives the options "password, normal", "password, encrypted", "Kerberos", "NTLM" and "No Authentification").

Now, I am not asked for new login data, but my mails do not appear either. It appears, that there is now no successful connection to the server (it keeps getting stuck contacting the host and sending login data; see image attached - in german).

Is there any fix to this?

Most of my email message filters do not run automatically but will run correctly manually. I am running Thunderbird 115.8.0 (64-bit) on Windows 10. I have 65 filters defined.

I have tried repairing the folders. I have even deleted the old folders and created a new folder. I deleted and recreated all of the .msf files. I have insured that the filer criteria is defined correctly (i.e. multiple condition are "match any", "contains", etc). These efforts have not corrected the problem.

This problem has been around for quite some time. Is there a plan to correct the problem or provide a newer version of message filters that works correctly.

Below is a copy of one of the Filter Log entries of an automatic filter failure. I have included the log entry of the filer being run manually following the failure entry. I have included a screenshot of the pertinent rule:

All'apertura di Thunderbird, mi si presentano 2 cartelle Bozze e altre 2 per Posta inviata e non capisco perché (vedi foto allegata). Cosa posso fare per eliminare i doppioni? Grazie

Running TB 115.7.0 on Windows 10 Educational. When I reply to an email on Thunderbird (on either of my two desktops) it shows up on both machines with the little arrow showing that I have replied. But if I reply on webmail (Outlook 365) the replied-to arrow never shows up on Thunderbird. The email will have a replied-to icon in Outlook 365 webmail, but Thunderbird doesn't show it. It's like TB can only see its own replies rather than all the replies that Outlook registers.

Hello,

I have started using Thunderbird these past few weeks as part of a move away from Gmail. I made some folders and setup some message filters to automatically sort my emails into those folders, to replicate my tags in Gmail. When I was doing this, one folder failed to create initially (let's call it "myFolder"). It simply wouldn't appear after trying to create it, even on repeated attempts, although I could still create other folders fine with a different name (so presumably myFolder was partially created somewhere in the backend and couldn't be overwritten). Anyway, I managed to solve this eventually, although I forget how. Maybe just refreshing the connection or restarting the program.

Anyway, this morning I updated to 115.7.0 (32-bit), and on applying the update I managed to briefly catch a message when the program restarted saying "Deleting myFolder". And sure enough, that folder has been deleted along with all of its email contents (which is rather a lot of emails!). There is nothing in the Archives nor Deleted folders. All of my other folders are still intact just fine. If I go to my \ImapMail\[server]\INBOX.sbd folder, I can see all the other folders there, but not the deleted myFolder one. And same story if I look in the folderCache.json or folderTree.json files.

I can also access the account in question via RoundCube and SquirrelMail web interface. In the former it shows all the other IMAP folders I created in Thunderbird, but not the one deleted on update. In the latter it shows the first folder I created in Thunderbird, but none of the rest (I think myFolder was the second or third I created).

I cannot see any kind of backup profile. I only appear to have an empty .default profile, and the active .default-release profile. There is also nothing new in my Windows Recycle Bin.

1. Can someone please help firstly with recovering the lost folder? Or at least all my emails that were in it?

2. As a second priority I would obviously be interested to learn what caused this, and how to avoid any risk of it happening again in the future? I am amazed that Thunderbird would automatically and permanently delete large numbers of emails in one go both locally and off the server, without any user interaction/confirmation, and without any way to undo it?

Might it be safer to just use local Tags in Thunderbird rather than synced IMAP folders? I wasn't sure how to manage those automatically with filters, but now I have found a suggestion advising that it can be done with Saved Searches. If I create a new Saved Search Folder, I presume that would then just be a local view folder which I could filter by tags into, and wouldn't have any impact on the server?

Best wishes,

Brian

Yes I have lot of emails, and I ma now using rules to delete old emails.

I have 12 email accounts for different activities I am involved with.

Why does Thunderbird keep downloading old emails everytime it restarts? Am I meant to keep Thunderbrd running all the time? Doesn't Thunderbird store downloaded emails on the PC?

My Thunderbird account is synchronised to my BT mail account using IMAP

Although the folders that i have built in my BT mail box appear on Thunderbird the contents of those folders do not, all I have on Thunderbird is empty folders

Any ideas why?

So, like I said in the title...my Thunderbird minimizes to the tray, and every time I open it from the tray, it isn't opened full screen...maximized. It is restored down....like when you press that middle button, left from the X. I don't know it is called, it says Restore down when you hover it. I'm using the latest x64 bit version, and my OS is Win10 Pro. Let me just say, that it happens only if I leave my PC for a longer period of time, couple of hour and it goes to sleep. Once it's awaken, opening Thunderbird is not the issue anymore. Only the first time. Any ideas?

I stopped receiving e-mails in Thunderbird last night and when I send them which works I get the message below and there not in my send file

our message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-lozendev@shaw.ca.

I subscribed to a blog as I usually do in Thunderbird but it ended up as a folder. I've tried to delete it but it doesn't go away. There are no posts in it either and resubscribing to the blog doesn't work - it just says I'm already subscribed. Any suggestions?

Hello :) I am using Thunderbird on Fedora 39. I am also using the OWL add-on which I guess is on a trial for the next 30 days.

Anyway; my one and only email account is hosted Exchange (office365) through Rackspace. When I set up Thunderbird to use my email, everything seems to work and work flawlessly with the exception of Contacts.

All of my contacts are listed, but they are all mostly missing their phone numbers and addresses. I have not LOST any data to my knowledge (My mobile devices and three other computers running either Windows 11 or macOS Sonoma still show all of the missing information). My concern is that if this info is missing and I go to put in a new address or phone number in Thunderbird, that I might mistakenly delete information when updating a record when it goes to sync.

Anyone know what is going on?

Hello, Recently, some attachments, such as photos, are no longer displayed as attachments in Thunderbird. This is not a problem in the mail program on the smartphone. Do you have any idea what setting I need to change to get the attachments displayed again? When I forward the mail, the attachment is displayed in the mail to be sent. I hope you can help me. Thank you very much.

Best wishes Stephan
