I want to change one of the passwords I have stored in Thunderbird. Asks for my Mozilla password but then rejects it. I even went through the whole "change my Mozilla password" ritual to make sure I have the right password and in fact it's the one that's letting me post here. But I can't get in to see my passwords on Thunderbird. Help?

I have successfully imported two gmail accounts and one plus.net account into Thunderbird but have been unable to get my outlook.com account to work. I keep getting "We can’t sign you in - your Browser is currently set to block cookies……" (https://login.live.com/cookiesDisabled.srf?uaid=d8765d38fd5349ada4d4d431073a1f36&mkt=EN-GB&lc=2057)

I use DuckDuckGo as my default browser but have also tried with Brave and Edge, turning off any available cookie blockers. I have set Edge to allow cookies but still no success. Can you advise please?

I have previously used Thunderbird for many years and intended to move back now that an Android app is to be launched, so this is disappointing.

I need help on my Thunderbird email program! It keeps asking for my password. Ive tried several. It does not work. [edied] @bellsouth.net I could use some help. I`m 83 and this isen`t easy any more. Ralph Toler

I changed my password on my aol account which is my email provider. I have the email configured to use OAuth2 authentication which previously worked just fine . When I now attempt to access my email a window opens up asking for my AOL username. I enter that and the next window says "Please Enable Cookies in your browser and sign in again" Not sure on how or where I do this. My browser is DuckDuckGo. Thanks so much

Problem It prompts "Unable to log in at server. Probably wrong configuration, username or password" when adding Gmail on my Thunderbird on Manjaro Linux. My Google account has 2FA and Authenticator enabled.

No google webpage asking for login popped out. (but Microsoft's webpage did popped out and asked me to do 2FA when adding an outlook account).

Tried to add and use "Google app passwords" but it didn't work for me.

All other of my emails worked well including outlook and several others.

This seems to be an ancient but long not fixed problem (?) 🤯 Could anybody here help a bit (?) Would appreciate that veeeery much!!! :3

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.

Trying to get my laptop PC (Windows) Thunderbird to accept change in gmail password. Laptop shows blown-up (Thunderbird, I assume?) screen asking me to click on "allow" button. No such button is visible: presumably it is off-screen? I've tried everything mentioned on internet to deal with this, and nothing works. Thunderbird + gmail worked perfectly on that Dell laptop until I changed the gmail password (using my desktop PC). Any suggestions would be appreciated. E.g., should I take the laptop to BestBuy or another service point? Or am I overlooking something? THANKS, Fred

I am getting following message and unable to login in my email account beside reseting password many times. " Login to server blackzeroarabia.com with username info@blackzeroarabia.com failed." please advise.

I set up a primary password, forgot it and set up another one, now neither work. I'm so fed up with Firefox i just want to delete it, but Mozilla support said do not delete the account without solving this problem.

I'd appreciate any help you can give.

I do use AVG and I have turned off the VPN while using Firefox to see if that helps.

Best

After a recent update to Thunderbird 128.9.2esr on April 17, 2025, I am unable to login to my gmail accounts through Thunderbird. Login to server pop.googlemail.com with user name *********** failed

I can login to my email accounts fine using gmail but not with Thunderbird. I have tried a number of fixes I found on the internet at the link below but nothing seems to be solving the problem.

Please any suggestions on a solution to this problem?

Thank you! Virg

I've followed Thunderbird setup according to "Automatic Conversion of Google mail accounts to OAuth 2.0 Authentication" (https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20) The failure is described in my initial post below:

Mozilla Support - Signin, and use of Thunderbird https://support.mozilla.org/en-US/questions/1484529#answer-1729438

LarryGad post (Reply to Ashley LambertonQuestion owner): I get the same screenshot Ashley posted above. But...clicking Allow doesn't download my Gmail messages. And clicking the link, Account Permissions, just produces a blank window. An idiosyncrasy is I'm the domain administrator for a "Free Legacy Edition of G Suite for personal use".

This paragraph may not be relevant to the above issue. I did stumble across the Account settings link (https://myaccount.google.com/general-light?pli=1) which contains the line: 'Connected accounts View and manage your accounts from other services' Clicking the 'View ...' link goes to https://profiles.google.com/connectedaccounts and displays the message: "404. That’s an error. The requested URL was not found on this server. That’s all we know." Highlighting the 'View ...' link shows https://profiles.google.com/connectedaccounts?authuser=0

Thanks in advance.

When I download my mail from the server, my system sends a password to verify who is downloading the mail. Where, on my end, is the password located. I have forgotten what it was and want to also access my account from my phone. Need to know what it is, not change it. Thanks Charlie TB 38.5

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?

I'm setting up a gmail workspace account. I know that imap is enabled and that authentication should work through oauth2. That's what I configure and TB confirms that it can connect to the account during creation widget.

I click continue, and a new window opens which contains a site from Google asking if I confirm that TB can access my account. I click on allow, and the content in that popup disappears, but the popup remains open. Just with a blank screen.

I've tried several times. Cookies and JavaScript are allowed and enabled.

What else could be wrong here?

There are many sites where I am unable to log in. One of these three things usually happens. 1. Fill out email and password, click log in, infinite loading with on some sites (like Spotify) an error about not being able to load. 2. Fill out email and password or the form, try to click send/continue/log in but I can not click it, it's greyed out. 3. Fill out email and password, get told it is incorrect. For any of these issues, if I switch to chrome (which I am trying to avoid) it works, it's just limited to Firefox.

I have tried disabling the advanced protection, that doesn't change anything. Any tips would be much appreciated and I will try to answer any questions as fast as possible.

Thanks in advance

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

I changed my Google account password just today. I have used Thunderbird on PC for Gmail without issues for years. I went into Thunderbird Saved Passwords and changed the appropriate line to the new Gmail password. I restarted Thunderbird and tried to send a test e-mail. I kept getting "Login to account Google Mail failed" with a box of 3 options, Retry, Enter New Password or Cancel. When I click on either Retry or Enter New Password, it doesn't give me a chance to enter a password and goes immediately into the same "Login to account Google Mail failed" box with the 3 options. I searched and read the support and one of the option is to remove the line from Saved Passwords and re-create it. I did that and tried to send another test e-mail. Now I'm still not getting a chance to enter a new password. I keep getting the box with the 3 options which doesn't allow me to enter a new password. There isn't a new entry in the Saved Passwords.

Strange thing is Thunderbird is receiving new e-mails fine. I'm just not able to send.

Thanks.
