Thunderbird Community Forum

Whenever I want to print an email the print preview doesn't show, it keeps displaying a spinning wheel. Printing also doesn't work (as in, I press Save, enter a filename and press Save; the dialog closes but no file is generated).

I already tried the Troubleshooting information -> Clear saved print settings, but to no avail.

Browser console screenshot attached. I'm using Fedora 41 and Thunderbird 128.11.0esr (flatpak).

Yahoo insists on OAuth2 but tb always complains about Javascript missing. I can enter username and then in the the next screen password but the process then hangs, signing in continuing forever.

I send a regular bulletin to 40 users. Those who read on a laptop or tablet are happy but those on phones report that in landscape mode all is well but in portrait the right hand margin is about in the centre of the screen.

Is there anything I can do to use the full width of the screen in portrait mode?

PDF filter doesn't work

Trying to refine my search to get only emails with PDF files attachment, only get an empty list when mails with PDF are in the base for sure.

Step by step with screenshots here attached sorted by A, B, C.

A - Basic search with "pdf"

     => 480 attachments files in emails 

B - Filtering A search to get only mails from year 2025

     => in 2025 only 27 emails with attachment - We see in the list result some emails with PDF files attached to it.

C - Trying to get only emails with PDF types attachment, clicking on the top left filter get nothing

      => It's a bug i guess.

Ubuntu 24.04.3 LTS Thunderbird 140.4.0esr (64 bits)

On 18 November 2025

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: <[10.252.0.16]>: Helo command rejected: IP address 161.178.137.204 blocked due to abusive authentication behaviour.

Can someone help with the above message

thanks Alan

Enough is enough—every update brings problems, crucial add-ons stop working, and now drag and drop attachments have stopped working. It's really inconvenient. Maybe it's time to stop this nonsense and implement paid subscriptions or purchases, but in a way that makes everything work.

It appears that any ESR version will auto upgrade to the Release version right after you close the program and shut your machine down. When you go back online, surprise!, you now have 144.0.1 installed with HALF your folders missing.

I have two accounts with Thunderbird (*@talktalk.net and *@tiscali.co.uk). Each account will receive incoming emails (with or without attachments - single addressee or part of a group email). Periodically outgoing emails are blocked, with the error message 'Sending of the message failed. An error occurred while sending mail. The mail server responded: Reject for policy reason. Please check the message and try again.' Usually the issue seems to fix itself - this tome it has lasted longer than usual. Please can someone suggest a remedy? Tony

I can't send Free-online emails on Thunderbird/Macbook, although I can receive them (see Error notification attached). I checked the Outgoing server settings in the Accounts settings which seem right (relay.free-online.net). This has been happening for about a week. Thanks for your help.

I have a bunch of e-mail addresses in Unified folders, all of which are my own except one, which is for a relative on whose behalf I do a lot of things. I'd like to have that account show up completely separate from the Unified folders. Let's call that account X, for brevity.

I've favourited X's Inbox and Sent items, so I can show them outside Unified folders. So far so good.

In the Unified folders Inbox Properties, folders to search chooser, I unchecked X's Inbox and all its other folders.

This is almost what I want, except that X's account, with all its folders still all show up in Unified folders. I'd like to move them as well.

Is this possible?

When I add attachments when replying to emails, the file icons on those attachments don't display. This only happens when replying, the file icons display when receiving emails. Have tried many things to fix this including using ChatGTP with no luck. What can I do to fix this?

Schönen guten Tag,

seit ein paar Wochen habe ich das Problem das obwohl ich meine Emails nicht gelesen habe meine Mails als gelesen angezeigt werden. Ich hoffe sie können mir helfen.

Mit freundlichen Grüßen

While using you site and looking at joining Thunderbird mail I have been cf charged twio amounts 1p and £34.99 by library hub .com I did not authorized These payments it is fraud I'm 71 years old and nearly blind and can't afford The loss of this money. Kind Regards James Robson

Here we go again! After spending a couple of weeks trouble shooting this issue, I thought I had it fixed earlier today.

After using TB for a couple of hours, getting rid of duplicate messages, etc., I shut it down. But when I decided to check emails one more time, the ORIGINAL problem is back, it will NOT delete messages.

I deleted all earlier installs, and did a complete clean install of 140.5.0esr.

Why do I get large blocks of scrambled text in my emails?

Sample

How do I make a backup copy of my Thunderbird email client, saving all the subfolders? I would like to then uninstall Thunderbird and then reinstall it, as a new user, and without losing any of my old user folders. Thanks. After I do this, will I be able to reload all the old subfolders and read those messages?

My email provider is terminating the existing email domain name, and replacing it with a new domain name. I want to retain all existing Thunderbird folders and emails for use with the new email. Example: username@q.com becomes username@myclk.com. (Yep, it's Centurylink.)

Can I change my existing Thunderbird account name and email and retain all existing folders and emails in the account? Some server settings would also be changed.

Or, do I need to set up a new account?

Thanks
