EDIT: Now its working.

After updating to v148 i got the same error

What was the problem??

What was the problem??

every few minutes a pop up of yahoo login appears, i ad the credentials and i get the error "something went wrong.We could not sign you in. Try again from a different device."

Sorry, what I mean is, what solved it for you?

If you didn't change anything to make it work, then the fault is likely the server.

i didnt do anything ..could be server problem and "fixed" itself after some days but is this going to happen every time there is a new thunderbird update? this didnt happen before..last 2 updates started doing it and cant use it as it popups every few minutes...

> cant use it as it popups every few minutes.

So "EDIT: Now its working." is incorrect?

well it was 1 month ago and fixed itself..so now after the new update again same problem ..is there a way to disable yahoo for the time being so i can be able to use thunderbird with rest emails?

have removed the "solution" mark from previous reply

Well it was 1 month ago and fixed itself so it was marked as solved-not by me-

and now after the new update have same problem..this was never happened before. it started from v147 maybe on major only (147+148) and not on small updates 147.1 etc.

pop ups appear every few minutes and you need to close it 3-4 times to close for good-until it reappears-

Is there any way to just disable yahoo mails so ill be able to use the application with rest emails?

If you have not yet been successful, please tell us:

1. With the password that failed with Thunderbird, can you log into the account(s) using the mail provider’s web interface (webmail)? (Note: you must use the account password, not an "app password" that was created by Yahoo) 2. What are the full domain name(s) of all the affected account(s)? (for example yahoo.co.uk) 3. Are cookies enabled in Thunderbird at Settings > Privacy & Security > "Accept cookies from sites …" 4. Are you able to login using Thunderbird after you do the following?

• At the top right of the Thunderbird window, click the menu button ≡ > Settings > Config Editor
• find mailnews.oauth.usePrivateBrowser (screen shot below - you can paste it into the search field)
• click the two-headed arrow icon to toggle false to true
• restart Thunderbird (make sure it has fully shut down before starting it up)
• retry the login

Report back if you were not successful after step 4 …

@christ1 Thank you for your reply.

1) tried with edge and logged in perfectly 2) mail is yahoo.co.uk 3) yes are enabled 4) not working same result

1. Can you see the entire OAuth dialog panel - no action buttons are missing? 2. No authentication dialogs are hidden behind what you currently see? 3. You don’t have the preference javascript.enabled set to false in Settings > Config editor? 4. Are you in the country in which you normally use the account? (rule out geoip) 5. Related to #4 above: are you using a VPN? 6. Is the authentication method in Account Settings set to OAuth2? 7. Are you using MFA/2FA? (enabling multi-factor authentication / two-factor authentication in your mail provider settings might be blocking you) 8. Are you running a local web server on your computer, or any other service which may occupy TCP port 80? 9. If you are using Windows, does it help to start Windows in Safe Mode? See https://support.microsoft.com/en-us/windows/windows-startup-settings-1af6ec8c-4d4a-4b23-adb7-e76eef0b847f If you feel the instructions are too complicated, printing them often helps.

1) i believe nothing is missing as i can click buttons normally 2) no 3) its True 4) yes 5) no vpn 6) yes 7) no 8) no 9) havent tried..

also something strange that happens today -havent tried since yesterday- is that it doenst give me the option to enter password..it just goes from username to the error and same happens on edge/firefox. havent changed anything from yesterday..havent restarted modem/pc

UPDATE: just tried again now

with thunderbird still same error, cant login with browser -edge- managed to login fine
