I use this constantly to file my read mail. I've blocked upgrading to Firefox 68 until this add-on is updated.

This review is for a previous version of the add-on (1.4.11.11).  This user has a previous review of this add-on.

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
