"save all" to save attachments stopped working. I tried selecting all and Control C to copy them, and that did not work either. Often need to save multiple attachments since I work from home.

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.

Hello! In Thunderbird version 141+, saving attachments from incoming messages is slow. The situation is as follows. A POP3 server and Thunderbird clients are deployed on the local network. When the Thunderbird client receives a message and it appears in the client as new, the user attempts to save all attachments (15 MB) and clicks "Save All." This process takes about 1.5 minutes. In Thunderbird version 115, saving attachments takes 5-10 seconds. Could you please tell me if there's a setting I need to disable in the Thunderbird client? Can I open the "Advanced Settings" in the client and see what specifically I can disable to speed up saving attachments? I've attached the mail server connection settings to my request.

Whenever I get an email that says they are including an attachment, the attachment is never there. What is going on and how to I get email attachments. Any help is appreciated.

Thank you

I would like to send three photos as an email attachment. It seems that Thunderbird only allows one attachment at a time. How can I send more than one photo in the same email?

I installed the latest version of Thunderbird on my new Windows 11 PC, and when I try to save an attachment without opening it, it doesn't save. I need to open it and then I can save.

The attachement of the mail for thunderbird android should be displayed on top of the mail, not on the bottom. This is to avoid scrolling down all the way on a longer thread just to see the attachement. Please consider this modification urgently.

Thank you,

Laurian

Hi-

I had this working then it magically stopped about a year ago and I can't get it back. When I try to open a pdf I get "...could not be opened, because an unknown error occurred. Try saving to disk first and then opening the file."

I have gone into settings and re-selected adobe acrobat and restarted but still can't open.

I am on a mac.

Thanks for your help! Crazy frustrating and time wasting issue.

Hi Everyone,

I am very excited about the new PDF signature feature in Thunderbird, awesome to not have to do this externally.

However, I am still trying to find a way to streamline a common workflow for me: I get a an email with pdfs attached where I need to insert signatures in a few places and send this back. My current workflow is the following: i open each pdf attachment, add the signature, save it to a file, and then open the email reply and reattach the correct files and all of them. It is this indirection via files that actually created the biggest headache for me, as it's a bit too easy to mess up here.

I also tried going via the "reply with attachments" extension, to have the reply email with all attachments already, but there seems to be no way to then edit them in thunderbird.

Am I missing something obvious for how to do this? Given that I am surely not the only one doing this, I am hoping someone has already figured this one out?

I can go to any File Manager and send a file to TB, but from within TB itself regardless of composing new or replying, I can only attach Media, as the app only invokes the Media picker when tapping the Paper Clip icon.

Android 14, latest TB from Play Store.

i have always used thunderbird and am now up to 64 bit thunderbird 144.0.1 on windows 11 25h2

everytime i am sent a pdf file as an attachment i'm having to get thunderbird to open the file before i can actually save it to disc

everything else, while asking me for a name & location to save the file simply doesn't

btw thunderbird is now configured to ask me what to do with the pdf file and it ALWAYS behaves the same

i don't want to have to open files like pdf's that may not be safe / virus free before being able to handle them

way passed the time you fixed this stupidity terry

Hi, RTF attachments won't open. I have set the default application(Libre Office) in Windows, and in Thunderbird. Thunderbird is up to date. So is Windows. I can save the file, then open it, and then delete it, but it's a recurring issue.

Please help!

Hi, Microsoft recently changed the way Shared folders in OneDrive 365 business are managed. I'm referring in particular to folders shared by other users within my organization. Now you have to create a sort of link to the folder which appears in My files. Previously I used the odrive client to sync all my cloud accounts (OneDrive, Dropbox and Google Drive). Because of the changes, those shared folders cannot be synced by odrive anymore and I had to switch to the official Microsoft OneDrive client. With that, I can now sync the folders on my local drive but I cannot attach files from those folders to a Thunderbird message. While the folders appears as a link in the root OneDrive folder when I browse it with Explorer, when I click on the folder I see the files are local copies synced in my filesystem. Yet, Thunderbird cannot access them and gives the attached following Send Message Error: Sending of the message failed. There was an error attaching kickoff_novembre2025_6slide_V2.pptx. Please check that you have access to the file. Obviously I could make a local copy and attach that, but it is not convenient at all. Any fixes available?

受信したメールに添付ファイルがあるはずなのですが、 > Content-Type: application/pdf; name="・・・・・・・.pdf" > Content-Disposition: attachment; filename="・・・・・・・.pdf" > Content-Transfer-Encoding: base64 と表記されているだけで添付されていない時があります。 添付データはそれほど大きくなく、600kbほどのサイズです。 Outlook等別ソフトで受信した場合は添付されていました。 ThunderbirdメールソフトからThunderbirdメールソフトへの送信分です。

何か考えられる原因はありますでしょうか？
