I removed Gmail from my Thunderbird after Gmail became unreliable. (I had Gmail coming through T-bird for many years with no hassles..). I then attempted to re-install the Gmail client in T-bird using Gmails directions. Gmail took over my Thunderbird account! I then removed the Gmail account completely... I now get a notice in Thunderbird to sign in with GOOGLE after all my T-bird imap access is done and Tbird is open. The page (Google notice) which appears asks me to sign in with Google account. I want to get rid of this annoying notice. The notice can easily be dismissed but it is really annoying when it appears every time I open T-bird. Any ideas or help much appreciated! ..Btw - I attempted to get help from Google and they dismissed my case saying it was contrary to their policy etc....!! Help!

Hello group!

Trying to set up a new email account on shaw.ca, I get a hard error message: "Unable to log in at server. Probably wrong configuration, username or password" from Thunderbird.

I can send & receive emails via webmail, so all is Kosher at the server side.

Except Thunderbird kicks up a fuss. There's a little dialog box that says "Checking Password", with a tiny blue arrow that moves back & forth, seemingly forever. And then stops cold with that message.

I am not the first to have this problem: https://support.mozilla.org/en-US/questions/1495062

His attached screenshots are almost identical to mine, but for the Hostnames being shaw.ca, rather than gmail.com.

And my flavor of TB: 128.14.0esr (64-bit) Thunderbird for Linux Mintmint-001 - 1.

Any suggestions, anyone?

Thanks in advance,

- Ralph

Unfortunately my laptop crashed with windows 10 on it. I have since had it fixed with windows 11 installed. However when I try to sign in to my Sky email account through Thunderbird (imap.tools.sky.com) my password fails. I have signed into my sky email separately (they use Yahoo) with the same password and the same password works fine so I can get into my email account with no problems that way. I am now stuck as I am using the correct password but Thunderbird is saying that the login has failed. So I am asking how can I solve this.

When I try to enter a password for any website after a few updates ago, I don't get the option to enter my password that's saved in my password list into the fields anymore. I have to manually search, copy, and paste the information in. The app will then ask me if I want to update or modify the login information that is unchanged from what should already be in my browser.

Regardless of whether I say yes or no, the password remains unselectable when I go back to that website, and when I manually enter the information, it again asks me if I want to update the login information.

Yesterday I attempted to set up an account on Hulu. Every time I put in a password, it was rejected. I tried multiple times thinking it was a problem with Hulu. Did not work. So I went to Chrome and was able to set up an account without password being rejected -- I wonder if there is a solution to this as I want to use FF -- thanks.

Have been running classic Outlook email in Win 10 for years, with a blueyonder.co.uk (Virgin) email address. Now moving to a new PC running Windows 11. Tried to setup Outlook email in Win 11, but Outlook keeps telling me that my blueyonder address doesn't exist though I still get emails on my phone and my old PC running Windows 10. Given up on Outlook and advised by a friend to try Thunderbird. Now trying to setup Thunderbird. It looks very hopeful; it found my Virgin account and setup corresponding server settings, but when I click on "Done" I get the message "Unable to log in at server. Probably wrong configuration, username or password." I have checked my password by signing in to Virgin, where I can see my emails. Dave.

After installing upgrade to 139.0.2, POP downloads failed. Last was on 6/19/2025 at 8:19PM. I deleted both saved passwords.. Went to AOL and generated a new APP password but there was no way to upgrade to it. I sent a test message to myself [ smtp] and AOL logged me in and TB generated the saved password oauth://login.aol.com (mail-w).

However even with shutdown TB and restart, there was no request for a POP password [ such as the new AOL APP generated one. What should I do? Is this a bug? I can read and use AOL mail on my browser [EDGE]. LKint@verizon.net

Hello, At one time I could login at home to view my Spectrum.net account on Firefox (default browser), now I get a popup which reads "This feature is currently unavailable. Please try again from home or contact us for assistance. "IDID-4000"

I get the same message on my laptop and desktop, both running Firefox. I can switch to the Edge browser and login with no issues. I have cleared cookies and used other suggestions I have read on the web, but to no avail. Any help would be appreciated!

Thanks! Tony

I can’t complete the steps to change to OAuth for my Hotmail account.

The Microsoft site says to change the Authentication Method on the SMTP Server dialog to OAuth. But the authentication method drop down list doesn't include OAuth. Here are the only options in the list:

• No authentication
• Normal password (this is the one I currently use)
• Encrypted password
• Kerberos / GSSAPI
• NTLM

I use Windows 11 and Thunderbird version 128.20esr (64-bit), Windows.

How do I fix this problem?

Suddenly I am getting a pop-up window on Thunderbird asking me to sign in to continue with Mozilla Thunderbird email. It populates my email address and after clicking ‘next’ it says.

‘400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know’.

i cannot send or receive through Thunderbird, at present. Who is the genius out there that can tell me what to do?

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

Since the latest update a Yahoo Mail sign-in keeps popping up...sometimes two different versions. It's driving me nuts. Should I uninstall/reinstall Thunderbird. It's so frequent for no apparent reason that I may have to give up Thunderbird and many, many years of use...and donations. thx, deanna

after update to Thunderbird 128.6.1esr, I can receive but not send email from my gmail account. I get the message Login to server smtp.gmail.com with username xxxxx@gmail.com failed

I have changed my passwords on 2 gmail accounts I import to TB. Usually when you do that and TB retrieves email from gmail, you get a credential popup because the password doesn't match. Usually when you get that popup you click "next" and put the new password in and everything works as it should. I have been messing with this for 2 days now. I get the gmail credential popup, but when I click "next" to continue, I then get an error 400 from google? You can't do anything else after that. That darn popup just keeps coming and coming every time TB tries to retrieve email. Anyone else having this issue and found how to fix it? Is it a TB issue or gmail/google issue?

Hi. From 27 feb I can't login to yahoo mail through mozilla thunderbird.

When I start thunderbird, new windows is opened with this link

https://login.yahoo.com/account/challenge/fail?src=oauth&client_id=dj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz&redirect_uri=https%3A%2F%2F127.0.0.1&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz%26code_challenge%3Dt6iqw87GVPZ649cCvOEh2L1hwkUluBhsrwxCdVTXAOY%26code_challenge_method%3DS256%26redirect_uri%3Dhttps%253A%252F%252F127.0.0.1%26response_type%3Dcode%26scope%3Dmail-w%2520ycal-w%2520sdct-w&acrumb=0EYriz7Z&display=login&authMechanism=primary&e=true&pcn=password&eid=3692

When I tried to login I see this information:

An error occurred.

We couldn't log you in. Please try again from a different device.

This is very strange, because I tried it on another PC and this is the same. It looks that yahoo even didn't try to check password, because this is not matter if I wrote correct password or different - I see the same information.

Please help. I have two yahoo mail account and this is the same.

Both accounts works well on another e-mail client and I can access to my account without any problem by browser. This is only thunderbird problem.

Yahoo has made changes recently, supposedly in the name of security, that have had quite the opposite effect for those of us who use Thunderbird for email on shared computers. Before Yahoo's recent changes, Thunderbird would ask users to enter their password before connecting to the email server. This is no longer the case. Now, when logging into Thunderbird, there is no dialog box popping up for entering a password, Thunderbird just automatically connects. This needs to be corrected. Hopefully someone at Mozilla is listening and will take action.

So far, the only work-around I have found has been to go into Account Settings, Thuderbird Preferences, Saved Passwords, and deleting the oauth password that was automatically saved when I jumped through Yahoo's hoops to get my email working again after they implemented their recent changes. This has to be done EACH SESSION and, if this is done, then the next time I want to get my email I have to repeat the process of generating a new oauth token by logging into Yahoo by way of my browser, which will then be saved once again in Thunderbird and will, once again, need to be deleted at the end of the session. This is obviously a colossal PITA.

Someone PLEASE FIX THIS!

I keep getting the sign in request (photo 1) and when I click the next button I get (photo 2), I have no idea what has changed or what I can do to stop it. I would be grateful of any help.
