My K-9 in Android suddenly stopped to work a couple of days ago. The server asks for autentification. I haven't changed anything. I've uninstalled and reistalled the app and restarted my phone a Samsung S22 ultra several times. The app is recognating some settings automatically but it doesn't accept my old password with 16 letters in a group of four with highfens in between. What shall I do, please? Something wrong with the server? The version of the app is 17.0 updated March 16th 2026.

how to change primary password manager to another 100% trusted password manager like proton pass, nord pass, bitwarden password manager etc.. in firefox.

In windows and android, if there is no feature means kindly add that features.

Attempting to set up a yahoo email in thunderbird 140.9.0esr(64-bit). The goal is to have this set up on multiple workstations, so I've made the adjustments recommended per this article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo#w_please-check-the-following-before-asking-for-support

So, the toggle for mailnews.oauth.usePrivateBrowser is set to true, site/third-party cookies are always allowed (no exceptions), and the authentication method is set to OAuth2. Using the recommended server settings for yahoo: imap.mail.yahoo.com : 993 smtp.mail.yahoo.com : 465

I am able to set up the initial OAuth. The window pops up, I log in using the account password then put in the texted code, then the window closes and I get an email confirming the login. Hitting done within Thunderbird after this has it check the password again, and it fails: "Unable to log in at server. Probably wrong configuration, username or password."

This is on a fresh Windows 11 install/fresh Thunderbird install.

I am not receiving emails on my phone. I have had to change my password on my laptop but don't know how to do that on my phone. It would be very helpful if you could tell me how to do it. Thank you. Nick

As above.

There are two options given "Deny" - when this is enacted the pop-up just reappears again "Allow" - the instructions indicate that if this is enacted data , including contacts, could be deleted. So what do we do?

Hi, i cant log in from my thunderbird from my outlook account. I can do it with two of my acounts but not with the third one with the adress daniel.r.76@outlook.com

Problem with Thunderbird that I use for mail and news.

I have set TB to start with a Masterpassword and store all other passwords. Since sunday I can't use TB anymore.

When I start it, it asks for the Masterpassword which I enter, then it starts and immediately blocks access to all settings because it asks for the newsreader-server password. I can not normally cancel that passwort request nor stop TB, I have to use Taskmanager to quit TB.

Starting TB with the SHIFT option allows me to start it in base mode - but it STILL asks for the newsreaderpassword and won't allow me to change anything.

How can I get access to TB again?

I just updated from TB 142.0 to 148.0.1. After the update, my Yahoo and AOL accounts display a login window and prompted to re-enter the login credentials. After I enter the email address and click 'Next' an error is displayed:

Edge: Too Many Requests

This appears to be a browser error. What is needed to fix this? I am unable to re-enable my email addresses.

When I tried to copy the link to a 'real' browser window I was able to get the verification code from the sites, but then got the error Can't reach this page at 127.0.0.1, connection refused which, of course, is the loopback address.

TB on Windows

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.

I can't find my password. I have the encrypted password. Could you please provide me with the unencrypted one. I am locked out of a good solution for want of this item. The encrypted password is in the login information: {"nextId":8,"logins":[{"id":7,"hostname":"mailbox://pop.orange.fr","httpRealm":"mailbox://pop.orange.fr","formSubmitURL":null,"usernameField":"","passwordField":"","encryptedUsername":"MEIEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECKOq5c7et8tSBBg8bhRC2mUKTBdmSXk1HOIw+kJxVt2gG/Q=","encryptedPassword":"MEIEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECOabVSCGHBLGBBiqEqUXu8w7N4eAi09k0ZOIVAcs0chiziM=","guid":"{a798443b-98d1-47aa-bfe6-130fccad60d8}","encType":1,"timeCreated":1747819721033,"timeLastUsed":1747819721033,"timePasswordChanged":1747896607191,"timesUsed":1,"syncCounter":3,"everSynced":false,"encryptedUnknownFields":null}],"potentiallyVulnerablePasswords":[],"dismissedBreachAlertsByLoginGUID":{},"version":3}

I would appreciate your help. My account has been locked out of a good solution for lack of a critical piece of information.

I have made no changes to the PC or mail midway through the day it suddenly said input password, the password is correct, but I get incorrect password message. The password works using browser mode.

Since the latest update a Yahoo Mail sign-in keeps popping up...sometimes two different versions. It's driving me nuts. Should I uninstall/reinstall Thunderbird. It's so frequent for no apparent reason that I may have to give up Thunderbird and many, many years of use...and donations. thx, deanna

Hello Folks: after having the 'invisible' band across the top of each page, it was advised I reset : was fine saved all bookmarks before hand etc. Now, I am having to log into my usual apps each time: eg. the Library, the duck.ai, the Fitness app etc. Was this a result of the reset: wondering if the duckduckgo Privacy Essentials extension and the FF reset (refresh?) in now in conflict: I am not a greenhorn but definitely not an advanced techy so laylman's terms please THANK you for your help with this.

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.

I JUST TRIED TO OPEN A DOWNLOADED EMAIL AND FOR THE FIRST TIME EVER I WAS TOLD TO ENTER THE PASSWORD TO OPEN THE PDF FILE I TRIED ADOBE ACROBAT AND THEN TRIED MOZILLA WHAT PASSWORD ARE THEY ASKING FOR, WHERE CAN I FIND IT THIS NEVER HAPPENED BEFORE THE LAST MOZILLA UPDATE

AND MY COMPUTER HAS BEEN WORKING KIND OF OK JUST RECENTLY I NOTICED AN UPDATE TO MY COMPUTER HAPPENED AND IT IS NOT WORKING VERY WELL

I CAN BE REACHED AT [edited phone #] OR AT [edited email and phone# from community support forum]

Every time I start-up Thunderbird, a series of 2 pop-ups from Yahoo open up: [ Sign in using your Yahoo account ]. I close the pop-up and a 2nd one pops-up. I close it and say 10 or 15 mins they pop back up in the same series. It's very frustrating. I can't tell if it's Yahoo or a scam cookie. I notice the URL at the top of page and it's the same one every time and every day. The same URL shows: "https://login.yahoo.com/?src=thunderbird&client_id=dj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--&crumb=uE2cxQuNxpE&login_hint= ..." <... it goes on for a few more lines. It's long. I went to Firefox and cleared all 'cache' and 'cookies' and they still pop-up in Thunderbird. Heck, they just popped up again while writing you! How do I stop this intrusion while using Thunderbird? Thanks, RonD
