Hello, in my version of Thunderbird (140.11.1esr (64-bit)) on Windows, attachments appear at the bottom of the message. However, I would like the attachment bar to appear at the top of the email: how can I do this?

Kind regards, Inès

I had received an important email that had 6 attachments. I was able to open them yesterday, but today the link to them at the bottom of the email is missing, so there is no trace of the attachments. Is there any way to recover them? I tried clicking on the inbox folder/ properties & then repair folder, but it didn't help.Thanks

I have a client who has been using Thunderbird for years - in the last couple of weeks when doing his normal scan to email he is suddenly getting this error message, after filling in the email details and clicking send

"Sending of the message failed - there was an error attaching xyz.PDF. Please check that you have access to the file"

Process is... 1. do a Scan to Email via the Brother printer console panel 2. Scan completes and opens the TB new email message - File saves into the default folder \pictures\cc4\email 3. Fill in the recipient, subject and message body 4. Click send message in TB 5. Error above is presented

I can open the the attachment within Thunderbird to check it and it opens just fine - the scanned file is actually there... But click the send button and that error is presented.

I can fix it by removing the attachment and reattaching manually from the email folder where scan is saved.

When I try it myself (remote support), either via the brother CC4 app or getting client to trigger the scan to email, it often works, but invariably he calls back after his next scan to email and it is broken again...

Scans were saving to a Onedrive folder originally, moved the save location back to the standard user/pictures/cc4 folder assuming Onedrive may have been interfering, but it is still behaving the same.

Anyone have any clues what might be going on here? The brother software seems to be doing what it is supposed to. I have reinstalled both the Brother software and Thunderbird with no change... Windows updates maybe?

In the interim I have him doing scan to file and attaching manually, but would be nice to get this sorted for him...

its an Acer laptop running Windows 11 pro 25H2, TB version was 150.0.2 originally but still doing the same on the latest 151.0 that I installed two days ago

Thanks for reading... any help appreciated

The attachment icon is missing from the message display pane in incoming emails in Thunderbird. Before it was always displayed at the bottom of the window. I have 'Display Attachments Inline' checked and I also repaired the Inbox folder but still no icon visible. I am using the latest version of Mozilla Thunderbird 151.0.

Last week I saved the attachments of an email to a new folder in Documents. Today I received a new email with attachments. I saved these attachments to the same folder. To my surprise the old files (from last week) got a new timestamp. The date is today and the time is a couple of minutes after midnight. Any idea how this is possible? PS. I'm using Thunderbird on an Ubuntu machine.

With 03.04.2026 they began to notice that the attached emails in eml format (the attached emails have attached documents, mostly pdf) sent from yandex mail stopped opening. Everything used to open well. Eml also does not save to disk. If you send the same files via Gmail, everything opens. Program version 150.0.1

Does Thunderbird use an internal PDF print driver? I can't print PDF attachments in color from an email. I've checked my print settings but Thunderbird only prints black. If I save the PDF file and then double click it, Adobe comes up and prints it full color. I'd appreciate it if it can brought to soneones attention.

Thank you.

I've noticed that if I attach a file to an outgoing message then use ctrl+enter to send the message, Thunderbird also opens the attachment. How can I prevent it from doing the latter?

Bei manchen PDF Dateien 2,7 MB bekomme ich die Fehlermeldung Datei beschädigt. im Originalpostfach ( t- online ) Zugang über Internet ist der Anhang ok. Wenn ich die Datei vom Server direkt ( z.B. t-online nochmals an meine E- Mail Adresse sende und dann über mein Thunderbirth Mailprogramm öffne, ist die Datei ok. Der selbe Effekt tritt auch auf meinem Lapptop mit Linux Betriebssystem auf. Was kann die Ursache sein?

I can't open an email attachment with last part rs6.net. This is a reliable email with important information I need for a church conference.

I tried to send something and Thunderbird blocked it with yellow box on the bottom i could not d find out where or how to remove or unblock t and i also get it in Drafts too but how do i remove in Thunderbird please tell me where and how to unblock attachment remove the yellow box to unlock something please

something about remote content  i think

Hello dear support team Some e-mails in the Inbox are of a huge size, like 32 MB and more, even without attachment. I already used repair function, but it stays the same. In Outlook, the same email is of normal size (80 kb). So, it is not the e-mail provider or the database at the provider. I have had this situation throughout several updates, so it is not specific to a certain update. The ones that have an attachment and the same problem (attachments of less than 1GB but show 42 GB) cannot be moved. The error dialog says: to big to move. Also, the attachments cannot be removed as they show 0 kb and the attachments name is crossed out. This is not true for all mails, but some have this problem. What do you recommend?

I receive emails from one source that's supposed to have a banner image at the top. In Thunderbird it shows the broken image icon and the image as an attachment. But in RoundCube it shows as expected.

The html shows:

The image part of the email shows: content-id: <piXdKIOofB>

I'm guessing that those angle brackets around `content-id` are breaking the display, such that it's calling that a mis-match.

I received an email with several jpg images attached. I click on them to open in MS Office Picture Manager, and all I get is a tiny box with a red X. I have tried several online help resolutions, yet no resolve.

Hi everyone,

I’m new to Thunderbird. I’m using version 149.0.2 (aarch64), and I’ve noticed that when I receive one or more attachments, I only see a file called winmail.dat.

Is there a way to view the actual attachments, whether they are PDFs or other file types? Thank you!

Hi, The goal is download attachments from a RSS feed. I set a specific folder so i don't have to select path for every single file. Then clicking on the file link and it should start to download but it is very unreliable especially when used on many files in sequence it silently fails. Related big problem is absence on any useful file transfer indicator like Firefox has. There is a "download manager" tab but it is completely useless. It does not show any progress and the view has no scroll bar so nothing useful can actually be seen there. Downloading using "save as" button works. So you should either fix the direct link download or disable the feature completely until it does work, to avid missing files, because that is the worst outcome.

In den Vorschaufenstern sind in Thunderbird seit Kurzem keine Anhänge mehr zu sehen. Habe ich unbewusst eine falsche Einstellung vorgenommen? Habe alles versucht, keine Lösung erhalten.

When I type the word "attachment" in version 149.0.2 I no longer get the warning bar across the bottom of the screen. I do have the "check for missing attachments" box checked in Settings.

I am working on a new laptop running Windows 11. Thunderbird was successfully installed a week ago and was running fine until I made a change related to OneDrive - attempting to remove OneDrive as a default location for files. later, I attempted to open an MS Word attachment to an email and got this message from Microsoft Word: "Unable to open the existing file: (C:\Users\..(myname)..\AppData..\Normal.dotm)".

I think my OneDrive action - removing a OneDrive folder from my C:/Users/..(name)../ location on my laptop - per Windows support directions, caused this. Maybe a disconnect between Thunderbird and MS Word? I can open other file types that are attachments.

Can you help explain and correct this problem?

Thanks
