Every time I start-up Thunderbird, a series of 2 pop-ups from Yahoo open up: [ Sign in using your Yahoo account ]. I close the pop-up and a 2nd one pops-up. I close it and say 10 or 15 mins they pop back up in the same series. It's very frustrating. I can't tell if it's Yahoo or a scam cookie. I notice the URL at the top of page and it's the same one every time and every day. The same URL shows: "https://login.yahoo.com/?src=thunderbird&client_id=dj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--&crumb=uE2cxQuNxpE&login_hint= ..." <... it goes on for a few more lines. It's long. I went to Firefox and cleared all 'cache' and 'cookies' and they still pop-up in Thunderbird. Heck, they just popped up again while writing you! How do I stop this intrusion while using Thunderbird? Thanks, RonD

I need to fix TB to send/receive/save emails after a power failure today, Grid outage at 13:40, Power restored 13:40. Computer restarted, TB opened but will not perform any send/receive/save tasks. TB Message Send gets Outlook notification - Authentication failure. Went to Outlook email, logged back in, test email I had attempted to send by TB is in Outlook, plus new emails in Outlook, but none in TB. Checked for TB updates, current as of Jan 15, 2026. Restarted computer twice. Outlook email works but TB does not perform any tasks. I lost no TB emails in my messages before the power failure, they are all still in my TB messages. I have Firefox Browser and Windows 11. I love TB. It has had cardiac arrest. Help. Ann

I have a Hotmail account and multiple gmail accounts. When I try following your (obscure) instructions for changing passwords, the box of passwords is only for my gmail accounts. None for my hotmail.

As Hotmail is very important to me, I'd like to keep accessing it through TB but you make it tough.

I am now not receiving my Hotmail mail and as I get too much traffic 200+ msgs a day, it will build. Please send simple, direct instructions on how to find and change the hotmail password, thank you.

Hallo, ich habe seit 2 Wochen Probleme mit der Authentifizierung meines Mailaccounds von AOL. Alles was ich Versuche funktioniert nicht. Ich bekomme jedesmal im eingeblendeten AOL Autentifizierungs Fenster die Meldung "etwas ist schiefgelaufen. Ich habe in meinem AOL Account schon mehrerer Male ein App Passwort für Thunderbird erstellt. Habe dieses App Passwort Thunderbird genannt. Konto ist ein SMTP IMAP Konto, die Ports stimmen auch. Ich habe mein AOL Mailkonto mittlerweile in Thunderbird komplett gelöscht und ebenfalls die AOL Passwörter gelöscht. Die Authentifizierungsmethode für outh2 ist angewählt und Cookies sind eingeschaltet.

Ich kann machen was ich will. Die Autentifizierung funktioniert nicht.

Woran kann das noch liegen. Ich bin mittlerweile ratlos.

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

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

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.

Thunderbird won't let me login and doesn't deliver my emails. I have reset my password and still can't get my emails. How do I get some assistance on this issue?

There should be a web interface to manage firefox account passwords, yet there isn't. This is seriously bad because it means the user has to install firefox to manage passwords. I installed firefox on mobile just to find out there's no option to select multiple passwords at once so i can delete all of them. Please delete all of them.
