Français: Bonjour, Presque tout mes icônes dans la barre des tâches, programme ouvert, sont bleu. Comment changer directement la couleur de l'onglet de Thunderbird dans la barre des tâches de Windows. Ce serait bien de pouvoir choisir pour retrouver facilement Thunderbird et lire mon courrier. Christian

English Almost all my icons in the taskbar, for open programs, are blue. How can I directly change the color of the Thunderbird tab in the Windows taskbar? It would be great to be able to choose so I can easily find Thunderbird and read my emails.

Whenever I attempt to download waiting emails I frequently get the message: "The STAT command did not succeed. Error getting message number and sizes. Mail server mailhost.zen.co.uk responded: Mailbox unavailable." This is a relatively recent occurrance - what can I do to resolve it?

Hello,

I recently upgraded to a new PC from Windows 10 to Windows 11. For some reason I can not open links in any emails, even if right clicking them. I have gone through all steps here: http://kb.mozillazine.org/Standard_diagnostic_-_Thunderbird but nothing has changed. I have disabled Win Defender completely and still no change.

Any idea what I am missing? I am at a loss at this point.

Thanks for any advice or direction.

SIMPLIFY THUNDERBIRD IT IS EXCESSIVLY COMPLEX. I CANNOT EVEN SEE HOW TO MOVE MESSAGES FROM THE INBOX TO THE RELEVANT FOLDER IN MY LIST. I PERSONALLY BELIEVE FIREFOX AND THUNDERBIRD ARE OVERCOMPLEX AND NEED SIMPLIFIED. SIMPLES. WHY CANT I COPY AND PASTE THE VERSION NUMBER. BLOODY ARESHOLES . AS I SAID IT IS BLOODY OVERCOMPLEX. AT THIS POINT I AM CONSIDERING GIVING UP ON WHAT IS CLEARLY AN OVERCOMPLEX PIECE OF SOFTWARE THAT REALLY DOESN'T LOOK GOOD EITHER AND THERE IS NO OFFICIAL SUPPORT SO WILL HAVE TO LOOK FOR AN ALTERNATIVE. COMPLETE WASTE OF SPACE TOO MANY COOKS SPOIL THE BROTH COMES TO MIND THIS IS WHAT WE HAVE HERE

Ever since the latest update, when I hit send for an email. It says it cannot send, I cancel, hit send again and it goes through. I have to try sending EVERY email twice.

Every time I log in and then every so often afterwards I get the pop up - you are about to override how Thunderbird identifies this site- for a now deleted mail.co.uk account. I have tried all the fixes suggested by Google but it still keeps happening and is driving me mad. It tells me the certificate is outdated or invalid and asks to confirm to permanently store the exception but just keeps coming back every time I click on confirm, it only goes away if I click cancel but then keeps coming abck.

Email will not send. Message-- "Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again." I am not sending to another person but testing with my personal email. Thank you.

- Linux ver 140.7.1esr (64 bit) my folders are now out of alphabetic order among other things Trash us now under 'T' instead of grouped near the sent folder and my Computer folder has a mind of it's own. It's not under C even after I changed the name. It is just stuck. Wha? tnx

This only recently started happening. This has been tested on 3 different computers. Windows 10 Pro on all three.

With VPN on: Bluemail works fine.

Thunderbird can connect and download messages, but when I try to send a message, it gives an error.

With VPN off:

Bluemail and Thunderbird both work fine.

I had TB on my desktop for years and finally got it also synced to my phone. Then with a failure with Windows 11 had to wipe clean the desktop and start over. Cannot reinstall TB. I obviously have the correct e-mail and password as I was able to log into Mozilla and submit this question. I believe it is a problem with my user name and what is on my phone setup does not work with my desktop reinstallation.

I have filled in an un-correct password a number of times due to incorrect language setting of my keyboard. Then the popup window for this disappeared, and I cannot find a place to enter password. What can I do? It is the password for outgoing email.

Running Windows 11 and TB 150.0.2. Can't recall exactly what I did, but after clicking on an email all unread emails are no longer in boldface. Any way to restore them? (New emails that come in are in boldface.) Thank you, Joel Hornstein jobby@att.net

I open Thunderbird and see the list of received emails as usual and I have a "Viewing Pane" on the right. In the viweing pane I can see a portion of the email. However, there is a line going through the top portion of the viewing pane email and I cannot see what is under the line. I then fully open the email and the line is still there.

I have tried everything I can think of to fix this to no avail. I have even shut down Viewing Pane in settings and even then when I open an email it is still there.

I am trying to get Thunderbird to function in similar manner of Outlook Classic but the simplest of settings such as viewing pane just won't work. Thunderbird is up to date and Cache cleared. I have attached two photos to show what I am seeing.

I have just transferred my website to crazy domains and in order to set up email they need DNS records for thunderbird. I dont know how to access this. Could you please provide these for me.

Hi

I'm using Thunderbird 140.5 on a desktop Mac running Sequoia 15.7.2

In Local Folders, my subfolders have subfolders. In both levels of subfolders, Thunderbird has spontaneously started disordering both newly created subfolders, and folders which I move from one subfolder to another using right click 'Move To'

Up until ten days ago, all folders whether new or moved, were listed alphabetically. Now, day by day, the disordering is getting worse and as someone with ongoing conversations with hundreds of clients, it is becoming impossible to work when I have to give so much time to slowly scanning through every folder looking for the relevant subfolder.

I don't know why I can't update this version, but I tried installing the newest version available (145) and used the 'reset folder option' which did not work either.

Also, setting up a whole new account instead of upgrading my existing account is a colossal faff and I'd rather not have to!

Aside from manually reordering (also a colossal faff), can anyone suggest something I might be missing in stopping this happening?

Thunderbird says I'm on an esr channel, if that helps

Thanks

For the last 2 months I have been working to configure Thunderbird to fully replace my Gmail UI usage after their recent change to workspace options and using data to train gemini. When you deactivate those gmail features the first thing you lose are tabs for your Inbox, your Updates and your Promotions.

So far I have used tags, ThunderAI, Ollama and a locally hosted LLM to replicate the sorting of my inbox, but now I would like to be able to configure the Thunderbird UI to allow separate tabs in the menu bar for different folders, in this case Inbox, Updates and Promotions. With Inbox still being the gmail hosted main inbox and Updates and Promotions now being local folders stored in my local thunderbird installation.

Can the Thunderbird UI be configured to display folders as tabs as a default setting? I tried the "folder selection" button under customize on the toolbar but that just gives me a drop down, which is not what I want.
