Thunderbird Support Forum

Hej Jag har installerat Thunderbird på en ny dator och då stannar e-posten kvar på servern fast de finns i Thunderbird. På den gamla datorn laddades de ner helt till Thunderbord. På den gamla datorn har jag version 115.11.1 (32-bitar) och där finns funktionen "Lämna kvar meddelanden på servern" att välja under serverinställningar och den rutan är urbockad. Den nya datorn har versionen 115.12.1 (64-bitar) och där finns inte den funktionen med. Hur gör jag för att Thunderbird ska hämta e-postmeddelandena och inte lämna kvar dem på servern. Tack på förhand. Johan

When I launch Thunderbird I get the following message:

Secure connection failed

live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

This could be a problem with the server's configuration, or it could be someone trying to impersonate the server. If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND Thunderbird then automatically downloads emails without asking me for a password. I have just migrated to a new desktop computer (MSI CUBI 5) and this started immediately.

When I try to send email I get a message telling me my outgoing server does not have a certificate, but this doesn't appear to be Thunderbird's problem?

I'm not happy about any of this? Can you advise me please where I should be directing my request for help? It doesn't seem like it should be a Thunderbird issue, but the address includes the word mozilla so I am sending it to you...

Thanks for any help you can offer, I really like (and support) your software. Margaret

I've encountered one message in Thunderbird that has remote content enabled (which I don't recall explicitly enabling). In Settings, under "Allow remote content in messages" (unchecked), the "Exceptions..." list is empty. I've also cleared the cache, switched to offline mode, and went back to that message, but it still shows remote content.

I keep getting the prompt* about new.thunderbird.net expiration.

Indeed, after opening https://new.thunderbird.net in Firefox, the subdomain uses the Let's Encrypt SSL certificate that expired on 22nd May 2024. This certificate list many subdomains by name.

For https://www.thunderbird.net (after opening it in Firefox), another SSL certificate file is used (issued by Google Trust Services LLC by on 13 May 2024) valid until 11 Aug 2024. It says it should apply to thunderbird.net and *.thunderbird.net, but the new.thunderbird.net still points to the old Let's Encrypt certificate perhaps?

• I know I could just allow the expired one as an exception

I have a problem with Thunderbird 115.11.1 with the POP3 server inbound.att.net. Someone on at at7t forum suggested changing from Userid/password to Secure Mail Key. I had previously set up two Keys with at&t, but AI have never activated them. I looked at one URL, and was able to change the settings for inbound.att.net. But I did not see anywhere to enter one of the Keys that I had generated earlier. When I tried to re-configure outbound.att.net, I did not see a OAuth2 option. I do not need to re-configure outbound at the present time, as I can send mail without a problem. But receiving mail does not work. Here is what I see in the error console log:

Here is what I changed: Thunderbird: Account Settings --> Server Setings --> Security Settings --> Authentication Method Normal Pasword -> OAuth2

                                                   Inbound.att.net: Port 995 --> 587
                                                   Connection Security: SSL/TLS --> STARTTLS 
   

What do I have to do to get one of my two Keys into the inbound Thunderbird configuration? Thanks.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

While using Thunderbird, it mysteriously stopped connecting to Yahoo Mail. This happens every few years and I think it's related to Oauth2 credentials.

I generated a new secure mail key and copied it into Thunderbird but that didn't work. So then I checked online, and one of the steps in the Thunderbird instructions is: "Select 'Server Settings' for mail account; Set incoming server 'Authentication Method' to 'Oauth2'; Click on 'OK' ". But Oauth2 isn't one of the options. The choices are normal password, encrypted password, Kerberos/GSSAPI, and NTLM.

I'm using POP. Tbird version 115.11.1.

All the gmail entries & passwords deleted, remaining email passwords replaced, as of this morning.

I replaced them, and then so did they. I just yesterday deleted my online life... I'm sure just a coincidence.

Here's half of one they used: M.C555_BAY.0.U.-Co2UA6qeq4JOFgsvOCkdA**pHYS5XqT3TfRXLZAdnUxGM361xXXF0iCTeAaY5pXNyRoEu7KvIh3*uCkYXNAKRvbL7UnBYVnODYaRQ8e5lPvftncJgK1yNc9TzeqTMW1BCwqdeBAjmbGg

Suggestions? (Other than accept the dark side & sell your soul)

I am writing to let the community know that, at least in my case, the guidance from TB 1/2024 KB article on Qauth2, [and linked Microsoft article], didn't solve the odd password behavior that began around January, 2024, between TB and my Microsoft hotmail account--which had worked perfectly with TB for maybe 10 years?

Beginning in January I typically received an error message that SMTP server login failed; please enter password. But after fixing that as per the KB article (first trying to maintain normal password, then when that wouldn't solve it, turning on 2FA, switching to Qauth2 with cookies enabled), it turned out for me that with Qauth2 and 2FA, I could send mail okay but then the Outlook.IMAP server would not connect so receiving emails stopped. Several times after this failure I tried switching back to normal password AND turn OFF 2fa in order to get Outlook.IMAP to reeive email...but then SMTP would keep requesting passwords, and every day or two i'd get a repeated request to reenter the Imap server password for receivfing also.

The only stable fix I found after weeks of livign with this and debating abandonment of TB came when I turned 2FA back on, requested an app password from my Microsoft Account, changed TB Server settings back to Normal password for SMTP and Outlook.Imap, and then entered the App password when prompted by TB for to eonnect with server for receiving and sending.

This has worked fine and apparently been stable, without new reqauests to me for passwords, for 2 days, whereas all other fixes in past couple months have not lasted longer than a day or less before TB requests again that I enter a password to connect with my hotmail account. (All through this my gmail connection via TB ahas remained flawless, thought I did get a request for a gmail app password, which I obtained and entered--just once and all has since been fine).

I don't know why several careful step by step attempts to do everything in Mozilla's Thunderbird KB and Microsoft articles suggested didn't work--for a residential Microsoft account, whether I tried to follow guideance for those experiencing SMTP problem only, or the Imap server connection generally.

My only guess about why my Win 10 desktop installation is different? I have Outlook for Android running on two or 3 different Android devices also, perhaps that complicated things?  I also used to have a mirrored account (in other words, name@hotmail.com is my main account, but I also had a 2nd "nickename" acct with the same name, set up as name@outlook. com.  

(But I removed that nicknamed acct in case it was causing any of my authentication problems; made no difference. )

Guten Tag,

siehe Anlage!

Diese Fenster öffnen sich alle bei nur einer Sitzung, auf nur einem Computer!

Klicke ich etwas nur einmal an ("Mozilla Thunderbird Email", "E-Mail-Adresse vergessen?", "Datenschutzerklärung", " "Konto erstellen" (Anzeige es liegt ein Fehler vor) oder auf "Weiter" passiert nichts!

Auf mich macht das den Eindruck das jemand an meine Anmeldedaten ran will!

In der Zwischenzeit bekomme ich auf diesen einen Computer auch keine Gmail´s mehr. Diese lese ich auf meinem Handy oder auf den anderen Computer!

Ich kann kein englisch und arbeite auch nur mit dem Übersetzungsprogram.

Auf diesem Computer habe ich das Programm deinstalliert und später neu installiert. Das Problem ist geblieben.

Meine Alternative E-Mailadresse ist hanssy58@web.de da gibt es keine Probleme.

Mit freundlichen Grüßen

Hans Sbrzesny

Hello,

see attachment!

These windows all open in just one session, on just one computer!

If I click on something just once ("Mozilla Thunderbird Email", "Forgotten email address?", "Privacy policy", "Create account" (message that there is an error) or on "Continue" nothing happens!

It gives me the impression that someone wants to get my login details!

In the meantime, I no longer receive any Gmails on this one computer. I read them on my cell phone or on the other computer!

I don't speak English and only work with the translation program.

I uninstalled the program on this computer and later reinstalled it. The problem remains.

My alternative email address is hanssy58@web.de and there are no problems there.

Best regards

Hans Sbrzesny

Hi

I recently changed my email address from johnbugler@phonecoop.coop to johnbugler03@gmail.com.

I receive Thunderbird 'flyers', and I want to ensure that they're sent to johnbugler03@gmail.com. If it hasn't been done already, please change my email address to johnbugler03@gmail.com.

Thanks and regards

John Bugler

A bit of an odd request, I know, but I'm trying to send encrypted email from Thunderbird such that only the recipient, and not the sender (me) can access the message once it has been sent. I direct Thunderbird not to save a copy in the "Sent" folder when I do this, but Thunderbird still encrypts the message such that my personal key can decrypt it. Is it possible to send a message that can only be decrypted with one key? I have access to the recipient's private key, if that helps.

Guten Tag,

ich benötige Hilfe das Googlefenster weg zu bekommen. Ich möchte mich nicht über Google anmelden, wenn ich es auch über Mozilla kann. Die Anmeldedaten von Mozilla funktionieren nicht.

Bitte sagen Sie mir, wie ich das Problem lösen kann.

In dem Fenster habe ich keine Möglichkeiten die Links an zu klicken, da dann das Fenster weiß wird. Ich kann es nur wegklicken, es kommt aber innerhalb von 5 Minuten wieder. Oder ich melde mich mit google an, was ich aber nicht möchte.

Danke für Ihre Hilfe.
