Artifacts have appeared within the program. Everything works fine in other programs.

This appeared after the last update. Judging by the picture, it's possible some of your icons are broken.

Please fix this. I can't use the program now.

Cut the cable a couple months ago. Have been using Firefox/Tbird many years. Stopped being able to access old email address of 25 years a couple days ago. When opened Tbird would always got to old email and say "couldn't log in" or something. Would cancel out of that twice, click on new address and collect new address email. Old email was always there, used it as reference during transition. At settings chose new as default and deleted old address. Looks like the boxes checked would not have deleted old email but it's gone. 3500+ of them. No warning, message, choice, nothing. took zero time. Cannot change in Mozilla login to new email address. Tried Tbird import tool, could seem to figure it out. Also need to update email in Mozilla. Help. Tks. x@yahoo.com

I have a backup file from another thunderbird installation. The profile in this backup contains a file named abook.mab. I suppose this is the address book. I would like to copy the addresses from this installation to my current thunderbird 147.0.1 (64-bit). Tools > import > address book does not work. Can you please advise me?

The task notification dialog does not show up, when Thunderbird starts and a task is overdue. It did so until some time in the autumn 2025.

The dialog shows up if Thunderbird is running when it is time for the reminder.

Is this changed behavior or a bug?

My "old" laptop (Windows 10) failed & refused to turn on ever again and it's been replaced by a new laptop (Windows 11). Long existing Email served by Mozilla Thunderbird has been loaded into new laptop but all that was loaded was about 6 current unread Emails in the Inbox and NOTHING in either Address Books (should be 30 or so in each) and NO FOLDERS (should be about 15 - 20). I own & run a business so all of this data/info is crucial but because the data currently lies within a laptop that died it appears it can't be retrieved by "normal" procedures. I need help here - lots of it.

I am a system administrator. My task is to set up corporate email for employees. I tried using the admx template, but I couldn't find the right syntax. With the policies.json is the same, I can't find any documentation that contains examples of these settings. Please guide me.

Preamble:

1. There are 34 email Accounts listed in left column.
2. (Image 1) When in "Mail" column I can see down to only the Account Name (address). There is only the Account Name and Inbox.. nothing else below that can be seen - no Drafts, Sent, Archives, Spam, or Deleted. Anything below is missing too.
3. When choosing "Account Setting", everything for last account shows up, plus Outgoing, Add-ons (Image 2). Too, we can see the Offline/Online Icon.

QUESTION: How may I fix it so that the last account shows all sub-sections of the account - i.e., Server Settings, Copies & Folders etcetera right on down to Online/Offline or at best, down to "Return Receipts" for the last account?

Thanks for volunteering, ~r

Dear Thunderbird Developers,

I am writing to express my frustration regarding the recent UI changes. After the latest update, the standard toolbar icons (Get Messages, Write, Address Book, reply, etc.) completely disappeared for me, leaving behind nothing but a search bar. Even using the "Restore Default Set" option fails to bring the essential navigation buttons back. While I can eventually fix these issues as a power user, these constant, breaking UI changes are a major problem for average users. For instance, my 65-year-old mother relies on a stable interface. Every time a rollout breaks the visual layout or hides basic functions, she is unable to use her email until I step in to fix what the update messed up.

Forcing users to manually rebuild their primary navigation toolbar after an update is not a "feature"—it’s a regression that alienates long-time especially elderly users who need reliability over constant redesigns. Please prioritize UI stability and ensure that "Reset to Default" actually restores a functional set of icons.

If you need further information I'll be glad to hear and hope you can give me an easy fix for this problem.

Windows 11 machine. I have 2 email addresses in my TB set-up, from different domains/servers, one is a Rackspace for my business and the other is Fastmail. I am repeatedly asked for the server password for every single incoming email, and occasionally asked for the SMTP outgoing password when sending. I have put Windows into safe mode and it still happens there. I just don't know what to try next. Thanks in advance, Laurel

I have a Hotmail account and multiple gmail accounts. When I try following your (obscure) instructions for changing passwords, the box of passwords is only for my gmail accounts. None for my hotmail.

As Hotmail is very important to me, I'd like to keep accessing it through TB but you make it tough.

I am now not receiving my Hotmail mail and as I get too much traffic 200+ msgs a day, it will build. Please send simple, direct instructions on how to find and change the hotmail password, thank you.

For many years I have had a Thunderbird Calendar, and have a large number of Tasks set up in it. I have now decided it would be convenient to link it to my Google calendar, so that it also shows on my new Windows 11 machine and on my laptop. I've gone through the process described in the "Create new calendars" article, to link the calendars, and the Google calendar is now appearing in the Thunderbird calendar, but not vice versa. How do I get the Tasks in the Thunderbird calendar to appear in the Google calendar?

I am running Thunderbird 140.7.1esr and Firefox 147.03 on my Windows 10 machine, which I used to set up the link. My Windows 11 machine has the same Firefox build, but Thunderbird 147.0.1, and the Google calendar display is the same, but I haven't yet set up the Thunderbird calendar on the new machine.

every email is being archived and I don't want any incoming out outgoing archive. I have no reason to archive thousands of emails forever. I manage them my self. How can I disable that feature?

What I have in mind is to be able to play a special sound when I receive a message from a particular sender in Thunderbird, sort of like a specific ringtone for a caller on a phone. I have someone whose e-mails I need to respond to ASAP, but I also need to work otherwise undisturbed on my computer.

Does such an add-on exist? If not, would someone consider creating one?

Thank you!
