Thanks for the reminder. I decided to test your method, and this is what I found: 1) Searching for add-on "Header Tools Improved" within Thunderbird provided no hits. I am using Thunderbird version 115, which comes with Ubuntu MATE 22.04. Thunderbird version 115 is not actually very old: it was released on September 5 2024 (about 18 days ago), and there is only a newer version, namely Thunderbird128. However, searching for add-on "Header Tools Improved" on the Internet did show version 4.7, which should be compatible with my Thunderbird (compatible with versions 115.0 - 125.*). I manually installed that version, and the add-on seemed to work fine. On addons.thunderbird.net, I clicked on other versions, and I then saw a new one labelled "version 4.8", compatible with "Thunderbird 126.0 - 132.*". That is probably the reason why Thunderbird was not showing the add-on at all. This is all very confusing. 2) Menu item "Header Tools Improved" only shows up in the context-menu, and only in the message pane. If you open the e-mail in a separate window, like I tend to do, then there is no way to access the add-on. The shortcoming with the pop-up menu is actually documented: "Due to changes in Thunderbird this add-on now only works with messages opened in the Message Pane. The Message and Message list context menus only appear when a message is visible in the Message Pane. The Message menu submenu had to be removed." 3) Option "Change header details" is not enough, you have to use "Edit full source". There is no find function in the text editor, so you have to visually scan for the "application/pkcs7-signature" you mention. In the particular e-mail I tried this with, there were quite a few headers to go through. 4) The e-mail had been sent from some Apple Mail software. Instead of "application/x-pkcs7-signature", the Content Type was "application/pkcs7-signature" (without the "x"). This procedure is definitely not for the average Thunderbird user. Other than that, your procedure did work. After making the change to the content type line, an additional attachment called "smime.p7s" appeared. I was then able to delete both the original attachment and smime.p7s too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/303140 Title: No more "Save all" / "detach all" / "delete all" for attachments To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/303140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
