Thunderbird Support Forum

I had setup a master password.

I forgot it ...now I can sign in to Thunderbird.

I have two accounts... [edited] @gmail.com

                                    [edited] @mail.com

Can you please remove the master password Or show how to deal with this.

My Gmail account opens fine in Chrome. Thunderbird can't get to it; it says my password is incorrect. I have tried it enough times to know I've not typed them all incorrectly.

I'm baffled, all help gratefully received.

I do not understand how to set Thunderbird for Comcast's two step passcode. How do I get the passcode, My bank sends a passcode by landline for checking and email for credit card.

Mac OS Sonoma, MacbookPro 2018. Cannot save passwords, cannot set master password. Works fine on 3 other machines, cannot work on this one, I need this to work. I have tried everything including re-installation. I have deleted various old files per suggestions, nothing works. If I enter my email password with checking the checkbox to save it, everything works fine. If I check the "save in password manager" it fails and the email fails. a master password is not set and nothing I have tried will let me set one. It's making me crazy.

Hi, This is shared computer, so I have set up a primary password to access Thunderbird. But If I click "Anuluj" (Polish word for Cancel) - look picture TB1.png, the program still opens, asking me for a password again, but now in English (look picture TB2.png). After denying password twice, the email list shows up in the backgruond while asking for password again. If I deny the password for the third time (look picture TB3.png) I can freely browse all emails there. Any ideas on how to fix this?

Hello,

I am getting a failed mailed delivery message every time I send an email.

The error reads:

host submission.antispam.mailspamprotection.com [34.111.121.216] SMTP error from remote mail server after end of data; 550 high probability of spam 1rITD-006zLY-2v

Reporting-MTA: dns; es81siteground.eu

I continually received the following pop up window "Sending of password for user ######@hotmail.com did not succeed. Mail server pop3.live.com responded: Authentication failure: unknown user name or bad password."

How do I fix?

I still need help with passcode. I sent a response about my first question passcode. Your webpage is very complicated and I do not understand it. I can't get to the last thing I did very easily. Currently I have remember my device turned on so no passcode is sent when I log on. I don't know how to turn it off. I have been working about a week on this problem. I think one message said you needed to input passcode when you are asked for password. I also do not understand how to change the password when asked for new password. Also, I have not been giving donations to Thunderbird because they only appear to accept credit cards.

We have 2 computers set up with Mozilla Thunderbird. On one of the 2, the outbound password was inadvertently changed. on the other of the 2, the outbound email works fine.

On the 1 the password was lost, I saw an option to view the password. I'd like to do that on the 1 that DOES work so I can re-enter the proper password.

Thank you,

I have a gmail account which works fine using Thunderbird on a Windows 10 computer. I am trying to create the same account on another Windows 10 computer using Thunderbird but it fails when trying to connect to the account.

I have checked the identifier, the password and the authentification settings wih OAuth, but it still fails. Any idea why and what is going wrong ?

I have a droplet and domain at DigitalOcean. I’ve added users and I’m logging into their mail accounts with ThunderBird. I can send and receive mail between these users, but I can’t get mail from these mail accounts to Gmail and vice versa. No error. Also, when I checked the BlackList status, I saw that my droplet-IP address is in the BlackList: RATS Spam, SORBS SPAM, UCEPROTECTL3. How can I solve the problem?

att.net email uses a "Secure Mail Key" authentication method... and it seems each time I allow Thunderbird to update itself, it 'loses' my att.net email password, forcing me to go back to att.net and start over, creating what AT&T calls "Secure Mail Keys".

My other email accounts (e.g., aol.com) don't have any issues following Thunderbird updates.

Is this a known issue with Thunderbird updates, somehow specific to 'secure mail keys'?

I've been using Thunderbird for a long time. I presently have version 115.4.3

I have always had to enter my pw to receive emails, and always have to enter it again to send emails. Why do I have to enter it twice?

Every other email client I have ever used only requires I enter it once.

I don't want to use Thunderbird to save my passwords.

Thanks for any help/suggestions.

I recently downloaded and installed Thunderbird but forgot my primary password. Have tried the solutions available at the Mozilla website with no luck. I have also deleted the program and my Mozilla account, and started over from scratch. Still no luck.

Can anyone tell me how to blacklist incoming emails from selected addresses?

I can get T-bird to send unwanted emails to the "Junk" folder, but there are some that I would prefer not to even show up on my end, but rather delete them before they even get here (Facebook being the prime offender - hundreds of people I have never even heard of sending baby photos, etc.).

I contacted my ISP and was told that I needed to do this from the T-bird end. I cannot find anything in the Support section that addresses this problem. Thank you, Wolfgang
