I read with great interest '''Creates multiple copies of drafts''' at https://support.mozilla.org/en-US/questions/1280432, and tried both suggestions with absolutely no success. In addition, my instance of T-bird (ver. 78.0) now has begun *SENDING* the automatic draft saves instead of saving them! One of my recipients received *SEVEN*, slightly different copies of the same e-mail message, complete with typos and attached photos! Furthermore, I thought it was a bug in the new T-bird version. So, I backed up all my files including my profile, then uninstalled T-bird, rebooted the laptop, then installed an older version of (ver. 68.11.0, as I remember). There was some improvement: The older T-bird didn't send the saved drafts, but it still saved multiple, serial copies. But wait! There's more! I am running both Win 8.1 and Kubuntu 20.04 LTS on my laptop as dual boots. So, when that last experiment failed so badly, I rebooted to Kubuntu, and ran the Linux version of T-bird (ver. 78.0 as well, I think. But I don't want to reboot right now to double-check.) Same story: Multiple, serial drafts! But then last night, the Kubuntu version of T-bird began SENDING multiple, serial drafts to the recipient! And both of the two Windows versions and the Kubuntu version committed the same error whether I used the "Save" button or the keyboard shortcut ( <Ctrl>-S). So, I am at a complete loss. I have no idea of what to do next. Or where to even continue looking. Wait! The thought just hit me that I'm using more or less the same profile contents in all three instances. If the problem lies there, what part of my profile would mangle the function of the "Save" command? What do I need to do to fix it? (Without losing all my other profile customizations.) Thanks in advance. Stan
