This is a great little tool, but after Thunderbird got updated to version 68.2.1 in Ubuntu 18.04, it has been disabled. I hope it can get fixed at some point.
This review is for a previous version of the add-on (1.4.11.11).A new version that works with Thunderbird 68 should be available soon. See https://github.com/adamroach/tb-archive-this/blob/master/tb68-update.md for details
