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

Trying to set up Thunderbird on new computer. I do NOT want to import anything but address book from old computer. I use Thunderbird to Gmail since I also have an Android phone and want to access emails with Thunderbird and Gmail. I downloaded the Thunderbird installer, but I cannot log into Gmail when the Thunderbird setup asks me to EVEN THOUGH I know I am using the correct Gmail password, it is rejected as incorrect. Do I need to set up a whole new Gmail account? I MUST use the same email address, and I doubt Google will allow me to set up a new account with that address.

Please help.

皆様、はじめまして。 先日、ThunderbirdにGmailアドレスも追加登録しました。 が、パスワード変更が必要になった為、Google で Gmail のパスワードを変更した後に、Thunderbirdに登録しているGmailアドレスでは受送信出来なくなりました。 従ってThunderbird での Gmail送信エラー画面でパスワードを変更しようとしたのですが「新しいパスワードを入力」への入力を受け付けてくれませんでした。 更にパスワードリストで変更出来るかとリストを出そうとしましたら、Thunderbirdがユーザー名とパスワードを聞いてきました。 でも、ThunderbirdはＰＣが変わっても、ダウンロード、インストールさせて頂くだけで、メールアドレス等の設定をすれば使えますので、敢えてユーザー名やパスワードを登録した記憶がございません？

結局、「その他」を選んだらPINを入れることによってパスワードは見られたのですが。 後でパスワードマネージャーのリストを見てもThunderbird は載っていませんでした。じゃあ、パスワードマネージャーは何というユーザー名を入れたのか？判らず気になります💦

Thunderbird が「メールアドレスのユーザー名」でなく？、単に「ユーザー名」と聞いてきた場合、何を入力すれば良いのでしょう？ 登録した複数のメールアドレスの中のどれかを入力すれば良かったのでしょうか？

その後、Googleから本人確認をしてきましたので、Gmailのパスワードを入れ、スマホで「はい、私です」をクリックしたら、ThunderbirdでもGmailの受送信が出来るようにはなりました。

ただ、もし、Thunderbird ソフトに対するユーザー名とパスワードがあるのなら、なんとかしないといけませんので、お尋ねしております。（初めてThunderbird を使わせていただいた頃のメールアドレスはスパムの為に削除して無くなっております。）

よろしくお願いいたします。m(__)m

When I try to add my Outlook account, the authentication process requires a password input rather than redirecting to Microsoft’s OAuth2 login flow. My Outlook account is configured as passwordless, meaning I typically sign in via Microsoft Authenticator, biometrics, or a security key. I have already tried deleting and recreating my Thunderbird profile, but the issue persists. Since this is my first time adding this Outlook account, there is no existing outgoing server (SMTP) entry for Outlook in Thunderbird’s list. I attempted to manually configure the SMTP server (smtp.office365.com, port 587, oauth2), but the same password prompt appears, and I cannot proceed.

I have multiple gmail accounts set up on Thunderbird. They were all working fine until I traveled overseas and came back. Then, all of a sudden, 1 gmail account stopped working. The rest kept working fine. I checked the settings and they were correct. I removed the account and tried to set it up again (about 10 times), but kept getting the same error message: "Unable to log in at server. Probably wrong configuration, username or password." The automatic configuration passed and I even tried manually configuring to the recommended settings to no avail.

The only thing I can think of is that when traveling overseas and trying to get online, Thunderbird and/or Gmail asks for further security verification, and I just avoided using Thunderbird altogether while abroad. Upon my return, I started getting this error message. It is extremely inconvenient to have to use the Gmail interface for only 1 email (my main email!). Does anybody know anything I can do to repair this? I'm almost tempted to use another email client altogether to make my life more efficient as the new setup is not sustainable.

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

How do I update the SMPT server password in Thunderbird. Updated IMAP pw and system receives email fine. Cannot send messages, "Outgoing server (SMTP) error". SMPT password needs update.

I am not able to login into my gmail account. Whenever I try to sign in, it shows the message as shown in the attached image. I have tried clearing all cookies and cache. Also removed all the extensions to see if it fixes it Please help me. I have Linux Mint 22 Cinnamon Firefox version 131.0.3 (64-bit)

After an apparent system-wide aol failure, I can no longer log in to my Thunderbird account. When I open it, the message pops up: "Login to server imap.aol.com with username Leisterr8@verizon.net failed." And it asks for a new password. I looked up my saved passwords and tried to enter them. But that does not work. I don't see how to enter a new password. I am able to log in to my aol.com account with my password. But that does not seem to be the same as the password for the Thunderbird account.

Whenever I go onto a Microsoft website, I have a terrible (consistently mildly inconvenient) time signing in. For whatever reason, it always tries to sign in with my school account instead of my personal account, and I have to manually change to the account I actually want to use. I don't know why it keeps defaulting like this but it's very annoying, what can I do about it?

I have been using the Thunderbird email client on my Mac for a long time to access my corporate Gmail account. (This is not a personal Gmail account, it is a corporate Gmail linked with Okta.)

In this corporate Gmail account, I do not have access to "App Password" settings or "Less Secure App Access" options. Everything was working fine until 25th April 25. On that day, I updated my Okta password, which also affected my Gmail account because Gmail is connected through Okta.

Since then, my Thunderbird email client has stopped working. It keeps asking me to allow Thunderbird to access Gmail, and even though I allowed it many times, the same pop-up keeps appearing. To troubleshoot the issue, I have tried the following steps:

• Reset my Okta password again to rule out any password issues. (I am able to log in to Gmail successfully with the new password and I can configure the same Gmail account with the Mac Mail app without any issue.)

• Upgraded the Thunderbird client to version 137.0.2.

• Cleared saved passwords and cleared cookies. (Note: "Accept cookies from sites" is enabled under Web Content settings.)

• Deleted the account from Thunderbird and tried to re-add it.

After this, I started getting the error: "Unable to log in at server. Probably wrong configuration, username, or password."

• While adding the account, I entered my name and email address, left the password field blank, unchecked "Remember Password", and filled in the configuration manually.

When I clicked on "Re-test", it detected the server settings correctly. But when I clicked on "Done", I got the same error again.

• Created a completely new profile in Thunderbird and tried again, but still faced the same issue:

"Unable to log in at server. Probably wrong configuration, username, or password."

• Uninstalled Thunderbird completely and reinstalled it, but the issue still remains. (Please refer to the attached screenshot.)

• I tried the troubleshooting mode, which disables all the add-ons and themes, but the issue is still the same.

Any help would be appreciated.

I'm not sure if this is relevant, but Gmail has made some changes (see the link https://support.google.com/mail/answer/7126229?visit_id=638814378228955739-1844270273&hl=en&rd=1). This might be causing the issue, though it was working fine until I reset my password on April 25th.

Have no idea to whom I was chatting a week or so ago, but outlook.office365.com was recommended to me as the incoming server setting for Outlook.com. Set TB that way and used it for a week or so. TODAY got a "failure to authenticate" error from TB (have had many such errors before). Went directly to Copilot, as I thought it would be the most authoritarian place to clear up Microsoft problems. It provided the informaiton below: Official Outlook.com Thunderbird Incoming Server Settings (2026) IMAP (recommended) Settings Server name: imap-mail.outlook.com Port: 993 Security: SSL/TLS Authentication; OAuth2 Username; Your full Outlook.com email address

Why this is the correct server Outlook.com, Hotmail, Live, and MSN accounts do not use outlook.office365.com .

Set outlook account incoming server to imap-mail.outlook.com and reset TB Immediately got: Mozilla Thunderbird Thunderbird Authentication failure while connecting to server imap-mail.outlook.com.

Can someone please tell what's going on?

i cannot get Gmail configured in Thunderbird. ive deleted it and re tried countless times but is keeps saying wrong credentials. ive followed all the guides and done everything . what is NOT happening , is Thunderbird does not open a browser to sign in with google. why?

I can get to the "stored passwords" box, but the email I need to change the password for isn't listed there. I have tried to send and receive messages but nothing makes a "enter your password" box pop up. All I get when it tries to retrieve messages from Gmail is a box to give my email, (just that, not a password) and then an error message that it won't work and there is no more information. I'm using Linux. I've had both this particular email address (as well as others) and Thunderbird for years, perhaps two decades, and I can't figure out what to do now. I was going to change all my email passwords for security reasons, but there's no way I can do that until I can get Thunderbird working with POP access again. Thank you.

Can't install yandex.ru mailbox to Firefox for Android. Using generated stecial application password did not get s result anyway

I live in Germany and use Deutsche Telekom's T-Online system for my main e-mail system, so my email address is: k.vanleuven@t-online.de

Due to some security problem, I had the change my T-Online e-mail password and since this time I can't send or receive e-mails from my German version of Thunderbird. Thunderbird asks me for the"secureimap.t-online.de" server password, but it doesn't recognize the new password that I have for my T-Online e-mail system.

I store my e-mails in various folders folders in Thunderbird and I want to continue using Thunderbird for my e-mail management.

I think I might have to re-install Thunderbird from scratch. Must I do this, if so haw do I save all my e-maile files?

Your help in solving this problem will be very much appreciated.

I upgraded to update 138. Thunderbird now requires me to enter a Primary Password. I never set a primary password. I cannot send, receive, or make any changes to Thunderbird.

How do I get out of this situation?

I've changed primary email some time ago and wanted to login using a new device. However, login fails with "Incorrect email case" and response contains my old email under "errors[0].extensions". After that, there is another request doing login with old email, which seem to be successful, however the whole operation fail and page only shows "Something went wrong. Please close this tab and try again.". Trying to login directly with an old email leads to "Primary account email required for sign-in" error. Please assist.

Whenever I sign in to sync my browser it keeps asking me to sign in again to reconnect to sync.

I've tried reinstalling the browser, deleting the Mozilla directory in %APPDATA% and reinstalling, removing account and signing in again.

No matter what I do I keep getting asked to sign in again to reconnect even though the initial sign in was successful.

I've been using Thunderbird 140 esr on Windows 10. I got a new computer with Windows 11 and decided to go to the Release channel for Thunderbird which is at version 142. When I try to set up my ATT/Yahoo account, it fails "Unable to log in at server. Probably wrong configuration, username or password." If I go to the manual setup, the authentication method I used for TB 140 on Win 10, OAuth2, isn't one of the options. How do I get that option back? I tried unticking the Create Accounts in the new Account Hub, but that didn't help. I also tried uninstalling 142 and installing 140 esr on my Win 11 box. It has the same problem: No OAuth2 option.
