After the most recent update to Thunderbird, I can no longer copy attached files on incoming emails to either my Quickbooks program or a folder on the hard drive by dragging over. Now must copy manually to drive. Can this be corrected?

My Thunderbird install updated from 140.13.0esr to 153.0.2esr yesterday and now I can no longer drag and drop any attachment from an email to any folder on my computer. I simply get an error message window with a title of "Error Moving File or Folder" with "Unspecified error" text. See image attachment.

I've tried a variety of folders, including Downloads, Documents, Pictures and other folders on local and external storage devices.

I can save the attachments using the Save All button, or by right-clicking a file and choosing Save As, but not by dragging and dropping as I have done so for years.

I have checked if Thunderbird is running in admin mode, which it is not, but have tested it both ways with the same problem occurring. I have also run Thunderbird in Troubleshoot mode, and the same thing occurs. I tried clearing the startup cache from the troubleshooting page with no change. Restarting the PC did not resolve the issue, and disabling my anti-virus(Avast) also did not make a difference to the issue.

Recently updated to ESR Meadow.

Now when I try to save attachment from an email by dragging and dropping to desktop, Windows pops up "Error Moving File or Folder - Unspecified error" and the operation fails.

And when I try to save attachment from an email by right click > open > Save dialog, the save filename is always "nsmail" but with the original file extension. E.g. a jpg attachment would come up as "nsmail.jpg", and a txt file attachment would come up as nsmail.txt. It does then save it, but why lose the filename?

It used to preserve the attachment filename, I'm sure! And drag and drop to desktop was such a convenient feature!

I have tried in Troubleshoot mode and behaviour is the same. I have tried in Windows Safe mode and behaviour for Save is the same; but drag and drop is completely disabled there (when I drag it, it shows a circle with line through icon).

Is it just me?

For a few days now I have not been able to print pdf files from within Thunderbird.

I am using 154.0b2 (64-bit) Beta version, but had the same problem with the previous version.

If I try and print the pdf it creates the file but the file is blank. This happens when printing to a physical printer or printing to PDF on the computer. The file is created but no content can be seen.

Workaround is to download the PDF and then print it from another app but it is annoying and did not do this previously.

Printing email content from Thunderbird works fine, to physical printers or to PDF files.

Any help would be greatly appreciated.

Hello,

I have an issue while detaching an attachement under a directory that has is name on a network share "G:\03_AFFAIRES Ad & FI\"

When i detache a file inside this directory the link in Thunderbird is broke because it become "G:\03_AFFAIRES Ad "

It was working in the previous version of thunderbird ESR 140.x

hello, i cannot seem to find a solution online, hopefully someone can help.

i often receive emails with images attached, and most of the time people don't resize their images. you can imagine over time this all adds up in the email storage folder total size.

i dont always need to keep a 6mb image version, it can be reduced after i am done.

i would like a method to resize the received emails image attachment, to at least still have a smaller copy for refence, but not end up with a huge thunderbird email account profile (in the email received not externally saved)

preferably a one click solution, or even a routine i can run on the file system, etc. or some way to edit the received email and its attachment in program.

thanks

I am running Thunderbird 140.13.0esr (64-bit) in Windows 11 25H2. I received an e-mail message that has a JPEG attachment. When I open the attachment, the image is opened with the MS Photo app. But in that app I cannot rotate the image. If I save the attachment on my disk and then open it with the MS Photo app, I am able to rotate the image. I am wondering why the instance of the Photo app invoked by Thunderbird does not allow rotation. Note that in the -Thunderbird uploaded image, the rotate icon at the top left is greyed out (and not available). Thanks.

When I get an attachment as a reply in an email it is with tmp file name. It cannot be opened because Thumberfird does not have a file association program, Using libre office with here I cannot find a file association either. Hoping for some help. Thanks in advance. PS. Should the questions be asked in English?

My emails that I send usually have the same attachments, but sometimes the emails are returned to me undelivered for various reasons, but I have realised that in some cases it's because 2 of my docs (although in PDF) don't want to go through unless I send them separately. Is there a way of increasing the size of attachments I can send?

When I trash an email, I can no longer view the attachments in the trash file, though the email itself remains until the setting for trash deletion has been reached. Since I have a gmail email address I can still view the attachments via the website for gmail. Does the attachment disappear on Thunderbird because of a setting - or is this a "feature" of Thunderbird?

Where does Thunderbird put attachments that I open (say a PDF I opened)? Sometimes these documents are sensitive and I want to assure any temporary copies are deleted, either manually but preferably automatically

Will setting "browser.helperApps.deleteTempFileOnExit" to "True" help?

Thank you.

Hello, I have a problem. I'm a Thunder Birth email client user. Until now, the default program for opening PDF files was Adobe Acrobat Reader. I was forced to delete it and replace it with Foxid PDF Editor. I changed the default PDF opening programs in Thunder Birth settings, see attachment number 1. Unfortunately, when composing a new message, I'm having trouble viewing PDF attachments. See attachment number 2. Please help.

Since Thunderbird update to Snap ``` 140.12.1esr (64-Bit) Mozilla Thunderbird Snap for Ubuntu ubuntu-snap-build - 1.0 ``` opening attachments ceased to work. What does NOT work (any more):

• Move mouse over attachment → right mouse → open (nothing happens)
• Move mouse over attachment → right mouse → open with (doesn't exist)
• Move mouse over attachment → doubleclick (nothing happens)
• Settings → Attachments → There is an empty box, and in the void beneath it, floating in empty space the text (backtranslated from DE): "Add a Filelink-memory service" or "Filelink-save service" or similar. The text is dead (not clickable), same for the empty box.

AFAIR, in the good old non-snap TB version, the box had file extensions and linked applications to open them. The box / links / extensions coud be added, edited, removed. But in snap crap it's all dead...

Any hints what I am missing?

I used to open attachments from received mails (like .diff, .patch), and also used it for final inspection of own attachments while composing mails.

Sometimes, the following message opos up: /run/user/1000/doc/1d06e601/binutils-sort-text.diff konnte nicht geöffnet werden, weil die damit verknüpfte Hilfsanwendung nicht existiert. Ändern Sie die Verknüpfung in Ihren Einstellungen.

When I try to forward email with attachment. I get a error message stating I dont have access for the attached file so every time I have to remove the attachment in the email and download the attachment from original email and attach to my email. Which is frustrating and time consuming process.

What I thick is there is storage path issue with my email setup.

Please assist to resolve this issue.

Something seems to have changed recently with the PDF rendering in Thunderbird. I received an email with a PDF file attached. When I view it on the screen it looks fine, but when printing it out from within Thunderbird part of the top of the first page missing; it looks like part of the image is behind a white rectangle.

When I save the file and print it using Acrobat Reader it renders fine.

I don't know what to make of this behavior, but it does seem to be new and there is a difference between how the file is printed from Thunderbird as opposed to printing using Adobe Reader.

Thunderbird 152.0.1 on Windows 11 PC.

I have an issue when trying to forward an email that contains an attachment. I receive the following error message:

"Sending of the message failed. There was an error attaching the file. Please check that you have access to the file."

I am using Thunderbird version 152 on Windows 10 Pro.

This issue only occurs when forwarding emails with attachments. Other email functions appear to work normally. Has anyone else encountered this issue? I would appreciate any help or suggestions. Thank you in advance.

Thunderbird 152.0.1 (64-bit) Build ID: 20260630165458 Windows 11 IMAP account hosted by Wedos

I found what appears to be a reproducible bug when forwarding messages with attachments.

Steps to reproduce:

1. Open an email with a JPG attachment. 2. Click Forward. 3. Save the message as Draft (IMAP Drafts). 4. Without closing the compose window, save the draft again.

Result:

The second save always fails with:

"An error occurred attaching 20260520_123800.jpg. Please check whether you have access to the file."

Error Console shows:

Failed to fetch attachment NS_ERROR_FILE_NOT_FOUND url=file:///C:/Users/<user>/AppData/Local/Temp/nsmail-1.jpg

I also observed that after the first draft save Thunderbird deletes:

C:\Users\<user>\AppData\Local\Temp\nsmail-1.jpg

However, the compose window still references this deleted temporary file.

Additional observations:

- Creating a new message and attaching a file from disk works correctly. - Forwarding a message without attachments works correctly. - Removing the forwarded attachment and attaching the same file from disk also works correctly. - Closing and reopening the saved draft restores normal behavior.

This appears to be a bug where the compose window continues using a deleted temporary attachment instead of the attachment stored in the IMAP draft.

Can anyone reproduce this with Thunderbird 152.0.1?
