After initial set up of an email to sign in to that email is impossible with the error message "Something went wrong" The only help is sign in from another device. This is not helpful at all!

This is particularly difficult when trying to set up an email on on an email programme such as Mozilla Thunderbird. Not but a few months ago this was never a problem as I have used this for years with Yahoo emails with absolute no problem.

This has all changed now (January 2026) making it impossible to set up an email by not being able to sign in to the account on the yahoo pop up screen.

This being tried on Linux and Microsoft windows on numerous browsers.

On one Windows computer in your pop up sign on window it just keeps saying turn on cookies in your browser but the cookies ARE TURNED ON? So it is just ridiculous.

A bug perhaps:- If I highlight various messages at once (I use shift and arrow) and then I press delete. When i subsequently navigate to any other message I can't read it, instead I see this message until I quit and reload Thunderbird: We're sorry, but we can't display this conversation, because the messages have been moved or deleted. Has anyone else noticed this and, better still, do you know how to work around it. I'm using Unified Folders by the way, in case that's relevant.

Using the Spell checker in long test the cursor gets behind the popup window of the Spell checker. I know this was _no_ problem in further vcersions. Please change it! So I have to close the window to find the caursor and restart the Spell checker

Neither plain-text nor HTML-signatures are being removed in replies, even though they are at the bottom of the email i'm replying to, prepended by the default -- tag on a dedicated line, as is the standard. I double checked that mail.strip_sig_on_reply is set to true. This happens on two separate accounts configured on my client. Thunderbird Version 140.6.0esr on Tuxedo OS (equivalent to Ubuntu 24.04)

Bonjour M. David et grand merci pour votre soutien. Je suis désolé de vous solliciter autant ! Pardonnez-moi mais je commence à être vieux (83 ans et demi …). Je commence mieux à comprendre votre proposition pour la commande « insérer » (on verra l’autre problème plus tard). J’ai cliqué sur la commande « nouveau message » en même temps que sur la commande « MAJ » (je pense que c’est celle qui permet de saisir une majuscule) mais cela ne m’a rien donné. En revanche, j’ai cliqué sur « paramètres des comptes » et j’ai cliqué sur « HTML » (voir image ci-jointe appelée « HTML »), mais cela ne change rien car je ne vois toujours pas comment ajouter la commande « insérer » dans la barre d’outils. D’ailleurs je n’ai pas vu la mention « composition et adressage ». Par contre j’ai essayé d’ajouter d’autres commandes dans la barre d’outils en cliquant sur « affichage » « barre d’outils » « personnaliser », mais je n’ai pas vu la commande « insérer » (voir image ci-jointe « barre outils »). Si vous avez le temps de continuer à m’aider, je vous en remercie bien sincèrement.

Hello Mr. David and many thanks for your support. I'm sorry to ask you so much! Forgive me but I'm starting to get old (83 and a half years old...). I'm starting to better understand your proposal for the "insert" command (we'll see the other problem later). I clicked on the “new message” command at the same time as the “SHIFT” command (I think it’s the one that allows you to enter a capital letter) but that didn’t give me anything. However, I clicked on “account settings” and I clicked on “HTML” (see attached image called “HTML”), but that doesn’t change anything because I still don’t see how to add the “insert” command to the toolbar. Besides, I didn’t see the mention “composition and addressing”. On the other hand, I tried to add other commands to the toolbar by clicking on “display” “toolbar” “customize”, but I did not see the “insert” command (see attached image “toolbar”). If you have the time to continue to help me, I sincerely thank you.

Hello,

I love Thunderbird, but I have recently moved to use a Android device for most of my work, and despite that there is now Thunderbird for Android, I found that there is a feature I really need but it is not working there: moving mails across different accounts. I work daily with four different accounts and sometimes I need to move some threads from to another. I had to move to a different email reader because of that, but I would really love to come back to Thunderbird.

Best regards, Patricia.

I am having a major issue with Thunderbird not saving Outgoing emails in Send Folder with IMAP setting.

Having three mailboxes two are set to IMAP and the third set to POP3. The IMAP outgoing mail creates an alert that mail was sent but copy not placed in your Sent folder due to network of file access errors.

Outgoing mail in POP3 save immediately to the Sent folder.

I am using the latest Thunderbird update:

• Server Type: IMAP Mail Server
• Server Name: IMAP.kinect.co.nz
• Connect Security: SSL/TLS
• Authentication Method: Normal Password

Outgoing Server [SMTP] Settings:

• Description - User name
• Server Name: smtp.kinect.co.nz
• Port: 465
• Connection security: SSL/TLS
• Authentication method: No authentication

Note: Authentication was changed form Normal Password in order to gain some traction on the issue during trouble, cause and correction actions.

Addendum: The PC was fitted to Starlink https://en.wikipedia.org/wiki/Starlink in preparation for use as sole source for internet connection. That was abandoned due to email issues.

Web info says plenty that does not exist. Eg Showing a context menu with "Delete selected" The web says can delete emails with delete or shift delete. It crosses the text out BUT does not delete any emails. Similarly emptying the spam folder is supposed to happen off the right click context menu. Nothing happens except last entry is highlighted.

Ideally I want to select a group of emails in the inbox with the find option then ctrl/A to select them all then delete key to clear them from the inbox. NB. None of these emails are still on the server, just in thunderbird.

I use a 32" monitor. In Thunderbird, I want to create some Message Filters. I bring up the Message Filter window and enter a filter. When I go to click the OK button to save the filter, I cannot see the button on the screen so I try to scroll the window via the scroll bars to find it but it won't scroll. I next try to shrink the window by using the CTRL key plus the mouse scroll wheel but nothing happens.

I cannot see any way to create and save Message Filters in Thunderbird unless the window can be reduced. Why does Thunderbird NOT use Windows facilities? I can generally shrink or expand a window by the Windows facility of CTRL + scroll wheel, but not so in Thunderbird.

I need some direction, please.

When I receive an event invite and I accept it Thunderbird only gives me the option to save the event to a local calendar and not to any shared calendars located remotely on a NAS. Is there a way to have Thunderbird also display the remote calendars? And after I accept an event is there a way to move the accepted event to a different calendar? Thank you for your inputs in advance!

I transferred Win 7 Thunderbird Profile (TB)to a Windows machine. It left behind all the other settings, such as when picking up/sending email, passwords are required at the IP to login, get email/send email.

QUESTION: Is there another TB area where the passwords are stored so I can copy those over to the new computer.

I posted this about a week ago, and when I come back, it's gone. That's why I am repeating myself.

A long timer ago, I was told by a user that Thunderbird does not need passwords. It does if you what to get your email. They are setting for each email user. There are 34 under the one TB.

I hope there is a transferable file because changing all the passwords and preference for each account would be the hard way.

I appreciate your taking the time to read this,

How can I transfer total messages including date and addresses to a word document for layout and summarising. I used to do this perfectly well in Windows Live Mail for many years!!!!

I am trying to set up the latest version on Thunderbird on my wife's old Gateway (WIN 7 home premium). The previous version of TB has problems so I deleted it and am starting over. I have manually configured this TB with the server info from the TB accounts on our other computers, but get the error as stated above. What do I need to check?

Bonjour, j'utilise Thunderbird depuis plusieurs années et j'ai plusieurs comptes de messagerie. Je suis à la version 140.7.1esr. Depuis plusieurs jours, j'ai le message "Saisissez votre mot de passe pour alain.jouenne1@orange.fr". J'ai beau saisir le mot de passe, rien n'y fait. Ma config est Windows 10 64 bits, 3 adresses Gmail, 2 adresses Wanadoo et cette nouvelle adresse orange qui me pose problème. A noter, lorsque j'ai eu cette nouvelle adresse, je l'ai configuré dans Thunderbird et elle a fonctionné. Et puis, un jour, j'ai eu ce message. J'ai même modifié mon mot de passe de messagerie, mais cela n'a pas fonctionné. Pouvez-vous m'aider ? Merci d'avance

My mom has been using thunderbird since 2015 like me on a debian based linux distro. I upgraded her PC lately. I double backed her .thunderbird account by copying her .thunderbird folder and using export to an external drive. It took an unusually long time to do this. Her email account is setup to use smtp but she has >1GByte size mapi folder. After getting the new PC up and running, only the smtp email is showing up. How can I access the email in her mapi folder?

Hello, I am trying to send and email with script and 2 photos but every time I try to send it I get a very quick flash of a small box with writing in it but it disappears right away, and my email is not sent. Why is this happening and how can I correct it so my email will actually be sent?

Thank you for any help you can provide.

Jean.

Occasionally (and recently much more frequently) while composing an email I will get a popup saying Tbird was unable to save to my Draft folder. Sometimes I will finish the note and send it only to find it failed to save in my Sent folder, too. Google pointed me to someone asking this very question in 2017, but the recommended solution doesn't work and the thread was archived.

I thought perhaps the problem was with AOL. I've noticed that while my Gmail mail updates very quickly, it takes AOL a lot longer on all my devices (iPad & iPhone using Apple Mail) and on my MacBook Pro with macOS Tahoe using Tbird. I'm guessing this is just an AOL issue.

So I composed notes using both AOL and Gmail as my SMTP address and waited. Eventually, BOTH popped up telling me of failure to save in Draft. Clicking Retry fails for a very long time (until you feel a little foolish doing it ;) )

I've been experiencing this problem for the past few months. I wish I could recall the specific change I made that preceded it. Sorry!

I'm not sure I can blame this one on AOL. Has anyone else seen this issue or have any ideas?

Can anyone please explain why, when I type an email and use Bold, Underline, paragraphs etc the program actually changes some text to symbols like asterisks & underscore symbol instead of underline etc that I did not enter and in general makes the body of the email look terrible when it is sent and printed out. I have tried typing the message in Word first and then copying to the email but it still seems to change it when the email is sent. Does anyone know why and can this be fixed? The last couple of emails I have had to prepare in Word, save as pdf documents and then send as attachments and this is a long and tedious process just to send an email message even if it is a long message. Thank you.
