Hello. I have been using Thunderbird for a long time. I have not changed any parameter, but I have very recently encountered a problem: For messages received between July 27th and July 28 th, the title of the message is displayed in Thunderbird, but the content does not appear. And it is impossible to delete the messages. I have just updated for the last version of Thunderbird 140.1.0 (previous version was 140.0), and now the new messages can be opened and deleted. But the messages received between July 27th and this update still can not be opened or deleted. Any idea of the causes of the problem, and how can I have full access to the affected messages ? Thank you

When I move a task on google mail for Android from one calendar to another, the task list on the Thunderbird desktop shows me two copies of the task! see image2 When I try to delete the original task in thunderbird desktop from the task list I get the prompt: see image1 When I change the calendar on the desktop, the same prompt occurs. I can delete the moved copy of the task from the new calendar, but the original task in the original calendar is undeletable! Clicking "Synchronize" for the original calendar doesn't change anything!

I had a disk crash on a Linux laptop and had to rebuild it from scratch. I have my entire home directory backed up, including the .thunderbird folder, and am now trying to use it by replacing that folder in my new installation with the back-up one as outlined in the instructions in the Thunderbird article about how to do this.

But after doing this, when I start Thunderbird, only the most recent IMAP download data comes up. None of the historical backed-up data is there.

Any advice you can offer will be appreciated.

I'm looking for a way to confirm deletion of a message before deleting it. I often use the `Home/End` button on my keyboard and sometimes accidentally press `Delete` button. In that case, a message could be deleted without me even noticing.

I know about the add-on (https://github.com/caligraf/ConfirmBeforeDelete), but it has a lot of bugs and is not compatible with Betterbird

Any idea?

This has been a recurring issue that comes and goes with time.

It happened to me a few weeks ago, than I updated thunderbird and it disappeared.

Now I am on the latest version it is happening again.

Basically, if I click a mail two link in say firefox, it can take up to two minutes to create the new message in thunderbird.

Alternatively, if I am clicking a link in thunderbird, to launch a website in say, firefox, it can take considerable time for that link to launch as well.

I'm currently on debian 12, running the very latest thunderbird.

128.13.0esr (64-bit) Release notes Mozilla Thunderbird Flatpak en-USthunderbird-flatpak - 1.0

This is a problem I've never really been able to solve, so I'm asking here. Any help would be greatly appreciated, as it's massively impacting my workday.

Thanks again

I don’t see the “Open in Conversation” option when I right-click a message. It simply doesn’t appear. Also in the Message menu on the toolbar, the “Open in Conversation” is missing too.

Interestingly, if I click on something like “1 reply” to expand the thread, then right-click one of the messages inside, I do get options like “Open Message in New Tab” or “Open Message in New Window” but still no “Open in Conversation”

I’m using Thunderbird version 140.0.1 on Windows 11

Thanks

Hi

I'd appreciate some help.

I have already set up two Mailcow email accounts in the same profile in Thunderbird. I want to set up a third but I've lost the "add an existing email" page. How do I find it again? I've checked the file menu or the three dash menu on the top right of the page and the option is missing.

How can I find it again?

Thunderbird 128.13.0esr (64-bit), Ubuntu Clean install a few months ago. I ave been using Thunderbird since (about) 2005. Love it.

When I create and send a message it is saved in the Sent folder, but when I reply to a message, the reply is saved in the folder of the message being replied to.

However, the option to "Place replies in the folder of the message being replied to" is unchecked, and the option to "Place a copy in: " Sent folder is checked. (I have tried both the 1st option: "Sent folder on..." and the 2nd option "Other..." Sent on... no difference.

So, Thunderbird seems to be stuck on Place replies in the folder of the message being replied to.

How do I fix this?

When I reply or forward an email (Thunderbird 182.12, MacBook Pro M3) with a keyboard shortcut and start writing right away, the initial characters are typed into the address bar and then only the focus switches to the main composition field.

This leads to some some other email addresses being selected depending on what the first few letters in typing are...

Is there any way that the focus is always first on the composition window and not the address bar?

Thanks a lot Harry

When I create a task, I set reminders for say 5 minutes before. But they never 'fire'. Reminders for calendar events work and I know Thunderbird treats Events and Tasks somewhat the same, but I don't know how to get them to fire off. Thanks

After the recent update to 140.1.0esr Lightning calendar reminders do not come up correctly (W11 if it makes any difference)

Previously reminders worked as they should, I have several daily, some weekly, fortnightly and as required, only the odd one comes up and one or two will come up but then disappear without my intervention

I have tried all the various settings to no avail

Someone in another thread suggested their old email address needed to be changed in Calendar properties, but I cannot find Calendar properties anywhere

I used to use Remindafox which worked better than Lightning but had to use Lightning when it was discontinued

Is there a fix for this as its totally unreliable at present

I just updated to version 140.0 and now my subfolders are out of order. Is there a fix for this, short of fixing it manually? I miss how they were automatically alphabetized. That went away when manual reordering was implemented. I can't grab a bunch at the same time and move them, since the order is so messed up.

I am guessing that my inbox messages disappearing had something to do with a Thunderbird update.

Pay attention mainly to the lines that mention "key".

   Access your AT&T Mail using your favorite email apps
   Synchronize other account info, such as your calendar and contacts, to your email app.

Create a secure mail key

It’s easy to create a secure mail key from your mobile device, tablet, or computer. Have your User ID and password ready to sign in to myAT&T.

   Go to your myAT&T Profile. Sign in, if asked.
   Scroll to My linked accounts, select the email account that needs a secure mail key.
   Scroll to Secure mail key, select Manage secure mail key.
   Choose the email address that you’d like to use, if you have more than one.
   Select Add secure mail key. Enter a nickname for the secure mail key to make it easy to recognize.
   Choose Create secure mail key.
   Select Copy secure mail key to clipboard. Make a note of your secure mail key for further updates.
       For security purposes, the secure mail key only displays until you select OK.
       If you lose or forget the secure mail key, you can always create new secure mail keys.
   Select OK.
   Go to your preferred email app, replace the existing password with your secure mail key. For an IMAP account, delete the existing password for both the IMAP and SMTP servers. Replace them with your secure mail key.

Good to know: Each device you use to access your email will have its own secure mail key. Additional secure mail key notes

Access your AT&T email account without an OAuth mail app or secure mail key

You can always read and manage your email through a Web browser at currently.com.

A secure mail key won’t affect your AT&T email password

You’ll still use the same password for your AT&T Mail account in OAuth-compatible apps, myAT&T, and other AT&T products like currently.com and webmail. When you change your AT&T email password, you won’t need to get a new secure mail key.

Keep your secure mail key as long as you like

Secure mail keys never expire.

Create a new secure mail key for a blocked or locked account

For safety reasons, we delete secure mail keys whenever we have to lock or block your account. If that happens, you’ll have to create a new secure mail key for each AT&T Mail account.

Give your secure mail key a nickname

Create a nickname to identify your secure mail key, especially if you have more than one. It’s much easier to recognize a nickname, like Ari’s email or Kelly’s email, than the 16 random characters you entered when setting up your email. Last updated: March 12, 2025

When I went through this process, it showed a key from 2024.

I merely deleted it and from the same page created a new key. After that 500 emails from the last week started downloaded to my inbox.

Happy again.
