13 Nov. I have been dealing with the problem of the requirement to sign in to Thunderbird using Google. It does not work. I enter my e-mail address, click next, and get a second window that says "Error 400". I tried to get some help with this through a company listed on the internet as Just Answer. That turned out to be a scam.

Someone called me this morning, offering to help me with this problem. The person was from the company The Web Services. While the technician from Web Services was working on my computer for a while to restore my Thunderbird files, he told he that they kept losing the internet connection to my computer. He said they had determined that they kept losing the internet connection, because some hackers were hacking into my computer, while they were working. He showed me a lot of evidence of hacking on my computer, indicating that the 2 technicians from Just Answer who had helped me the day before through long chats were hacking into my computer the entire time they were chatting with me, going through steps they said would solve the problem with having to sign in to Thunderbird using Google. I think the people from Just Answer had tried to create a Thunderbird back-up profile, but had not done it correctly. As a result, all the data within Thunderbird was lost. I cancelled my subscription with Just Answer today.

The technician from The Web Services was able to restore my Thunderbird, including the many local files I have. Some additional formatting of the site still needs to be done, and the correct server settings need to be set up. That is to be finished tomorrow morning. The Web Services person also sold me an anti-hacking firewall, which is supposed to also provide network security.

I am concerned, because on the Mozilla support page, it specifically states that Thunderbird does not offer phone support. I gave this company access to my computer today, so they could restore my Thunderbird files. The Thunderbird files have been restored. Now I see that the issue with trying unsuccessfully to sign in to Thunderbird using Google is still there. So I am right back where I started over a week ago, trying to find someone who can solve the issues that come up when I try to sign into Thunderbird with Google.

I am somewhat suspicious of the company The Web Services, because they called me and offered to fix the problems I am having with signing in to Thunderbird. Please let me know whether it was unwise to let them work on my computer today. Could this be another scam? Thank you.

Trying to set up My outlook email account in Thunderbird. Enter the correct info (User and password) and get incorrect password when I am 1000% sure I am entering the correct password but because there is no way to make any manual changes because Mozilla thinks they have everything set correctly, when they don't, I can't add the account. The manual evidently only works if the password is correct?? I can set the account up obviously in Outlook both on PC and both Outlook and Mail app on the IPhone using the same password but not Thunderbird??

Hello Thunderbird Support,

I’m having a recurring issue with Thunderbird continuously showing a Google login popup, even though I’ve already removed the Gmail account from Thunderbird.

Here’s what I’ve tried so far:

Deleted all Gmail accounts from Account Settings.

Removed all saved passwords (including OAuth tokens) from the Password Manager.

Deleted these files in the Thunderbird profile folder: logins.json, logins-backup.json, key4.db, cert9.db, pkcs11.txt

Deleted Gmail folders from ImapMail and Mail.

Checked “Manage Identities” and “Outgoing Server (SMTP)” — no Gmail entries remain.

Restarted Thunderbird multiple times.

Despite all this, the Google verification window (accounts.google.com) still appears when Thunderbird starts.

It looks like Thunderbird is keeping a hidden OAuth reference to the old Gmail account somewhere in the configuration files. Could you please help me identify how to fully remove this cached Gmail authentication so the popup no longer appears?

Thank you for your time and assistance.

Best regards, Khaled Ben Ali info@baktradingtn.com

non riesco piu'ad accedere a Thunderbird prima attraverso il browser mi chiedeva l'identificativo e passoword di yahoo.it ora invece con la richiesta della password principale non riesco a fare piu'nulla e non si accede

T-Bird one Yahoo of six accts, repetitive “ENTER CREDENTIALS” My T-bird release: 144.0.1 (64-bit) Desktop: WIN 11 Pro – with all updates

For the last few days, I have not been able to obtain emails on my desktop T-Bird for one of my six Yahoo accounts. And, I cannot send any emails from the account

BUT, I can access the target Yahoo email account via my desktop Firefox, via Android T-Bird and via Android/Firefox. And all incoming and outgoing emails are present. Stymied, I changed the Yahoo acct password. After the change, these three work domains perfectly as before. And again, all incoming and outgoing emails are present.

BUT, the repetitive error with my desktop T-Bird for the one Yahoo account persists. The POP-UP provides a long string in the URL window and the only text shows: “Edge: Too Many Requests” >>>>>>>> I’m not using EDGE [Yahoo must use EDGE for the login error POP-UP] The window in the bottom Task Bar displays: “Enter credentials” [repetitively – ad nauseum].

This is the copy of the Yahoo URL in the POP-UP: https://login.yahoo.com/?src=thunderbird&client_id=dj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--&crumb=mdAGY49jGd8&login_hint=name_of_email_acct%40yahoo.com&redirect_uri=http%3A%2F%2Flocalhost&pspid=954010027&activity=thunderbird-imap&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--%26redirect_uri%3Dhttp%253A%252F%252Flocalhost%26response_type%3Dcode%26scope%3Dmail-w I changed my email account name in the display above to: name_of_email_acct; all else is verbatim.

For clarity all six accounts work without encountering "Enter credentials" on the desktop via Firefox, my android via T-Bird app, my android via Firefox. Five of the six work on my desktop T-bird.

I did not add any extensions in the last week. I did disable all extensions (and restarted) with no change in behavior. I put a 25 cent piece on the keyboard to appease the computer gods – no change.

Yup: cleared cache and cookies. Deleted password from desktop T-Bird repository, but the new one is not recorded. Changed authentication from OAuth2 to Normal and back again- no change

Yes, I waited multiple hours to try again, with no luck.

Thoughts ????

I am operating on a pc with windows 11. i have Thunderbird, v. 141. I know my email and password for <redacted>@prodigy.net works, but T-bird won't let me sign in, using the password.

I had used T-bird back in 2018, so there are about 1900 files in it, but that file number is not only limited in date to around 2018, but there are thousands more on my prodigy.net (ATT) server extending up to today and going back farther than 2018. I know the incoming imap.mail.yahoo.com, port 993 with encryption SSL/TLS entered into T-bird. I know the outgoing smtp.mail.yahoo.com pathway. T-bird, as far as I can see, does not ask for the outgoing port, 465. Encryption is the same as above.

When I try to sign in, I receive the "retry, enter new password" message. No luck in retrying or reentering.

I can access my email through my server and through Apple apps on other devices, but not on this computer through Thunderbird.

I've made sure Thunderbird is unblocked as an app in Windows security. I can't think of much else. Help please.

Every time I try to access my email account I get a message that the "email account failed" and asks for my password (and sometimes new password). But when I enter the password I keep getting the same error message!

Until yesterday, I had no issues accessing my Yahoo account. However, all of a sudden, the Yahoo login popup has started appearing.

After entering the password, I get the error: "Something went wrong. We could not sign you in. Try again from a different device."

I checked and tried following:

• The authentication method is set to OAuth2.
• Cookies are enabled in settings
• Tried Yahoo account password and app one time password
• Deleted account in Thunderbird and created from scratch. The same login popup appears but fails the same.
• Deleted all cookies from yahoo in the "Show cookies" dialog in the setting.

Any help is appreciated.
