Running Thunderbird 128.2.3esr (64-bit) on Ubuntu 24.04. In Settings > Filed & Attachments, the pdf content type is set to Use System Handler (default).

  1. Compose a message, add a PDF as an attachment, and save the message as a draft.
  2. Go to the Drafts folder, select the message you saved, and double-click the attachment. The default helper application opens the file.
  3. In the Drafts folder, double-click the message to open it, and then double-click the attachment. The following message appears:

Double-click the attachment. The message /path/Downloads/thunderbird.tmp/nsmail.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences.

Why can I open an attachment from a message in the Drafts folder, but not from the message itself?

I guess this is another example of the sand boxing in ubuntu going wrong.

Cannonical have changed to snaps and that restricts a whole lot of things https://ubuntu.com/core/docs/security-and-sandboxing
