Thunderbird Support Forum

Lately I have been getting a lot of spam and have identified all coming into my inbox as spam. Now many are automatically moved to junk mail box and that is a good thing. Unfortunately it also seems to be slowing Thunderbird down. I am afraid that many of the "Filters" generated may be duplicated. Is it possible to see them and maybe edit them to reduce the impact on my system?

I've used Thunderbird for years using a POP setting; Network Solutions would prefer that I use IMAP. I don't know the difference, but they must and prefer that it be IMAP (netsol-imap-oxcs.hostingplatform.com) (PORT: 993. When bringing up the settings in my mail account, it doesn't allow anyone to change that field. What can I do? I want to use Thunderbird; because of this particular setting I haven't been able to, and must instead log on to Network Solutions and go through their email interface. Thank you.

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

Dear Sir/Madam,

I use the Thunderbird email client on my Microsoft Windows 10 desktop tower PC in order to access my Gmail account using POP3, using "only" my email address and password.

However, I note that Google plan to introduce more stringent and tighter sign in/authentication methods from September 2024 as follows:

Does Thunderbird have a workaround for Google's plans please?

Thanking you.

Hi

I cant find an Add-On for blocking ads in newsletters.

How can I block the very annoying Ads in newsletters? These newsletters from mainstream newspapers are a real imposition.

How-To block ads in mails with Thunderbird?

I have had a client for whom I use an outlook.office365.com "thing" and get/send e-mails through their domain.

In prior Tbird releases it just accepted whatever credentials Tbird presents

Recent release - I still authenticate just fine - can receive and transmit e-mails without issue. But every couple of minutes I get a nag screen asking me to login to login.live.com. I dismiss the nag screen, and can still transmit and receive e-mails. This screen is initiated by a Thunderbird process (I know this because if I kill a Thunderbird process in task manager, the screen goes away and everything works as expected. )

I really want no part of the Windows "Live" thing, and have no idea of what "helpful" changes it wants to make, and so I do not login.

"Settings" are set up with cookies set to yes. OAuth2 seems to be selected.

I see no settings that I could use to suppress the nag ... is there anything I can do???

Thanks in advance.

Hello: I can't seem to receive emails from a specific address from a professional office (with their own URL), which I have never (not knowingly) ever classified as JUNK, ... I have checked my Junk box, Deleted Box, and my filters from __@Bell.net, from which I download to T-Bird. That email addr or URL is NOT blocked, and I have put that addr on my "SafeSenders" List.

I don't see that email anywhere else in T-Bird Folders,, and the sender had to call me, and resend from a diff address, their own Gmail acct.!

And I can send to them, to few ppl in that office,... And I don't get any emails from anyone @the URL, meaning no other staff from that URL can send anything to me!

Did I accidentally classify it as JUNK, but I never received anything from the beginning,.. So I do NOT believe I would have set it as Junk...

I have checked ALL settings in T-Bird and at __Bell.Net in my settings, but to no avail.

Pls help, Much appreciated, Az

I went to passwords to change my password and one of the email ids - bobmater@comcast.net - is missing. There’s no account listed to change the password. All my other emails addresses are there. I think when you changed over, you deleted my account somehow.

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.

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.

I have not been receiving replies to adds I have on Gumtree, to my primary email address, denisj51@msn.com. Gumtree has advised me that my email client, which is Thunderbird, is identifying them as Spam, and is deleting them! I check the junk folder of that account regularly, and they are not sent to that folder. I would like to stop them being deleted. How do I do that ? Thanks for your help. Denis.

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

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.
