I am running Thunderbird version 128.11.0esr (64 bits) on Windows 10 Pro. I have defined, in Windows, the default program for .doc and .docx files to be LibreOffice Writer and this works fine when I click on such a file in Windows.

But when I got a docx attachment in a Thunderbird email, and clicked on it, nothing happened. When I right-click on it, it just offers to open (not to select which program to open it with). I have to save the file locally, and click on it in Windows in order to open it.

This is very frustrating, all the more so that it used to work. I tried adding the two following lines to the prefs.js file, to no avail - no change:

user_pref("network.mime-handler.external.application/vnd.openxmlformats-officedocument.wordprocessingml.document", "D:\\Program Files\\LibreOffice\\program\\swriter.exe"); user_pref("network.mime-handler.external.application/vnd.openxmlformats-officedocument.wordprocessingml.document.useSystemDefault", false);

Any suggestions? Thanks!

I cannot open attachments directly in an email with a double click, Probably since a week or so back. I have to copy the link address and insert it into a web reader. There is no command in the settings as I can see Quite a nuisance, Best regards, Gustaf

I see that any emails I sent using my outlook/microsoft account, two copies of that sent emails get generated under 'sent' folder when it should just be one so each time I have manually delete one copy. I have not seen this issue with other providers like Gmail, Yahoo or iCloud (Apple).

The other issue is which I have only started having today is that when I am trying to attach files the dialog box from which I can select the files open briefly for like 2 seconds (with no contents visible) and then disappears.

I was in the process of searching my files to attach one to an email when the attachment window suddenly expanded from approx 50% of the screen to almost full screen and I can find no way to reset it. I can see the sideand bottom edges of the window, and move the expand/contract arrow on the cursor to these sides and the bottom corners, but it does not operate, and there is no button to minimise or adjust it. I have just checked and it is operating perfectly fine on both Firefox and the main Thunderbird window, and email viewing windows. Is this a change to the program settings - it appears to only apply to the "Attach" setting - viewing attachments and emails are as they always were.

I occasionally receive HEIC as attachments. Opening the attachment defaults to my Adobe Acrobat which also cannot open HEIC. Is it possible to set the default open to Paint or something in Win11? Thanks.

hello

I don't seem to be able to attach and display a photo while sending an email. I transfer the image over but all that appears is a small square with no image displayed. Attachment doesn't seem to work either.

I'm on a MacBook Air

any help would be appreciated

Since the most recent update, Thunderbird doesn't load the email when clicking on the entry in the inbox, and then when double clicking to open in a new tab, the main window is blank with a Loading... text on the top left, and the URL shown above starts with chrome://

Running Thunderbird 146.0

I recently installed 145.0, was running the latest esr release before on my Windows laptop.

Now when I try to drag a file into an email to attach it, I get the black no smoking sign. Only way to attach is to use the drop down menu. Drag & drop was working fine in the esr version.

Drag and Drop attachments to the desktop stopped working again with Thunderbird 145. Steps to reproduce: You receive a mail with an attachment. You drag an attached file from this message and drop it onto the desktop of your Mac to download it. The attached file is not saved to the desktop (or any other folder I tried). This is on MacOS 26.1 MacMini M4. Please fix asap.

Hello,

When I try to save attachments from emails directly on my Computer, they never arrive at the destination folder - not individual files nor "save all attachements". Although the procedure '(left button menu - save - [navigation through file system till to the destination-folder] - save here') is "normal" and does not give any error message.

I can only save attachements, when i first open them (e.g. in word), and save them from there in its destination folder. This is quite a complicated procedure .. one should be able to save attachments directly from Thunderbird, without opening it.

What is the reason for this problem? Are there any options, is it a local problem (but it is a brandnew Laptop) or is it a bug in Thunderbird?

When T-Bird sends a message with an in-content photo, is that photo compressed to save space and transmission time?

I converted from Eudora. Eudora would compress in-content photos to save space and transmission time.

If T-Bird performs a similar action, is that compressed file saved somewhere?

Hi,

Where can I change in the settings the default Attachment Save(As) Folder / Directory. That Folder is also used by extract-em (for "save individual attachments"). On my installation it defaults to c:\user\myname\desktop but I can't find a way to change that location.

Another question : is there a way to disable the standard TB attachment Save(As) (shown at the bottom of a message) and replace it completely by extract-em ?

Thank you

I got an email with a dozen or so mp3 files attached and wanted to download them in one go onto my android phone. I chose "download complete message " thinking that would work. But no. The files don't appear in the downloads folder so I'm going to download each one separately. But I'd still like to find where the "complete message" was saved so I can delete it. Regards, Ian

Dear Thunderbird, I am using version 128.10.2esr and I have noticed lately that in my Inbox the email From have all been given the same incorrect senders name. This usually happens to emails that contain an attachment How do I correct this ? Thank you. Regards. Steve Hawes.
