Thunderbird Community Forum

I recently updated from a very old version of Thunderbird. The new version no longer shows the little popup messages at the bottom of my screen when automatically checking accounts for mail at the designated interval. As I have numerous email accounts (all set up as POP mail), set to check at different intervals, these popups were useful to me - they also showed when I manually checked an account, or all accounts - this also is not happening anymore. Have they been discontinued, or is it possible I turned them off? I did change some things to suppress nags to update Thunderbird during the time I was using the old version, and unfortunately didn't keep a record of those changes. I'd appreciate knowing which function in about:config controls this feature so I can check to see whether it's set correctly. Thanks!

For 2 years have been trying to get Thunderbird to access my mail from The Messaging Co. My old Win 10 laptop has no problem. My new win 11 laptop won't. I have configured the servers over and over but everytime I try to access Thunderbird I get "could not connect to mail server: the connection was refused". Who is refusing the connection? And why? I have re-downloaded Thunderbird several times but the problem persists. I am using Firefox. And using the in and out servers as per my win 10 laptop.

Hi! I hope you are well. It's my first time trying Thunderbird. I have the Linux Mint app. (seems to be the latest version available from the Linux Mint app store)

I attempt to sign into my Outlook.com email address on Thunderbird.

When I type my Outlook email and password and click Done, Thunderbird says configuration found in Mozilla ISP Database and it tries to pop up a browser window. Some website like login.microsoftonline.com is in the URL bar, but the browser window closes immediately without displaying a page.

Thunderbird say authentication failed. Either the entered credentials are incorrect or a separate username is required for logging in."

What do you think about the cause of this issue? Is this possibly an issue with my Outlook account or the Linux Mint version of Thunderbird?

I found a similar issue mentioned from a few years ago:[https://www.reddit.com/r/hyprland/comments/17q16cg/thunderbird_authentication_window_is/ https://www.reddit.com/r/hyprland/comments/17q16cg/thunderbird_authentication_window_is/ ] Where they used Linux and Thunderbird would open and close the Outlook window without giving a chance to login to the Outlook account.

On my computer, I tried: type a yahoo address into Thunderbird and click done and it opens a Yahoo website login window. So Yahoo seems to work, Outlook doesn't. Outlook's login window disappears by itself.

I was wondering if you have any suggestions for me? Is this the wrong place to report bugs (if you think its a bug)? (The Thunderbird app takes me to this place when I click Help > Share Ideas and Feedback.

Thanks so much for your time. :-)

Thunderbird info: Thunderbird for Linux Mint mint-001 - 1.0 140.8.0esr (64-bit) Linux Mint 22.3 - Cinnamon 64-bit

Login problem after Thunderbird 148.0 (64-bit) (update) as a client for Yahoo accounts - Google accounts continued to work without problems after the update. Yahoo accounts can now only be accessed via the website. A new app password generated in the Yahoo account is not accepted in the Thunderbird browser window, nor is the original password. Any tips would be appreciated. Thanks in advance.

I've been upgrading from Win 7 and Thunderbird (TB) version 68.1.1 (32 bit) to most recent TB Version 145.0.7632.117 (Official Build) (64-bit) NOTE: From a old Dell Inspiron 580 to Alienware Aurora Act 1250.

With new system and TB, I can export with handy-dandy exporter for TB 145.0.7632.117 but need them off old Windows 7 box. I see that the Legacy Add-on "Password Exporter" doesn't have versions high enough to work with most recent TB. And, I can't find a exporter for the old TB.

I have tried listing them in the old TB, but can't Capy/Paste. I made good quality screen caps and pieced them together in to one list. I was hoping to put the screen cap through a OCR but too costly for just one operation, and won't put it to a Online OCR - not when the image contains such things as ID';s and passwords.

Is there any way the data and passwords can be extracted from the old TB?

Many thanks for your help,

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.

hi today thunderbird started showing yahoo popup login and after adding credentials i always get "something went wrong.We could not sign you in. Try again from a different device." Also popup once closed it opens instantly.

i can sign in normally from browser. thunderbird version is 147

is there any fix about this?

thanks for any help

regards

I didn't see anything better in choices when setting topic in the "Which topic best describes your question?" related to the site having both English and Spanish mixed together. See attached images. To fix this I log out - delete the login cookies and cache, close browser, revisit Thunderbird site.

I posted this question some time back but didn't receive any helpful answers and don't know where my post is. In the upper right-hand corner there is suppose to be 3 symbols. One to lower the app, one to make the app full screen or partial and one with an X. I have jumbled symbols where the 3 good ones are. It does it in trouble shoot mode. I tried disabling addons but I can't get the normal symbols back. Here's what it looks like... Thank you for any help.

Currently I have one email account bulk forwarding every incoming email to another email account. Both are using Thunderbird. This is not being done using a filter. I set this up a couple years ago. I want to end this practice, but I can't remember (or find) how to do it. Any ideas? Thx, Bob

tried Click the blue “Settings” button at the bottom of the home screen. 2. A new left sidebar appears. 3. In that sidebar, click Account Settings. • This is the real place where accounts can be removed. 4. Now you should see a window with your email account listed on the left. 5. Click the top line of your email address (not Server Settings, not Copies & Folders). 6. Look at the bottom left corner. 7. You should now see Account Actions ▾. 8. Choose Remove Account. tried ✔️ Do this to reveal “Account Actions” 1. Look again at the left column. 2. Find the line that shows your actual email address. • It will NOT say “Email.” • It will NOT say “Local Folders.” • It will look like: yourname@provider.com 3. Click that line once. 4. Now look at the bottom left corner. 5. You should now see: Account Actions ▾ 6. Click it → Remove Account.

Preamble:

1. There are 34 email Accounts listed in left column.
2. (Image 1) When in "Mail" column I can see down to only the Account Name (address). There is only the Account Name and Inbox.. nothing else below that can be seen - no Drafts, Sent, Archives, Spam, or Deleted. Anything below is missing too.
3. When choosing "Account Setting", everything for last account shows up, plus Outgoing, Add-ons (Image 2). Too, we can see the Offline/Online Icon.

QUESTION: How may I fix it so that the last account shows all sub-sections of the account - i.e., Server Settings, Copies & Folders etcetera right on down to Online/Offline or at best, down to "Return Receipts" for the last account?

Thanks for volunteering, ~r

Can get(POP3), but can not send emails to a newly created personal outlook.com account.

the following error occurs when trying to send mail: Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)

all my setting are correct per thunderbird and microsoft:

  (smtp-mail.outlook.com, port 587,  STARTTLS, OAUTH2, xxxxx@outlook.com)

thunderbird error log file contains the following: . . . mailnews.smtp: S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox. Visit https://aka.ms/smtp_auth_disabled for more information. [CH5P220CA0005.NAMP220.PROD.OUTLOOK.COM 2026-02-28T23:29:21.878Z 08DE7703D4D1982A]

SmtpClient.sys.mjs:452:17 mailnews.smtp: Command failed: 535 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox.

Based on my understanding its seems thunderbird is using SMTP AUTH instead of OAUTH2 as required for newer personal outlook.com accounts. Is my assessment correct? If so, is there a fix?

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript

If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

I have several subscribed IMAP folders. I have a schedule set to check them every hour. But only the Inbox folder is checked. All other folders are checked only if I access them myself. Help me pls.
