Rated 5 out of 5 stars

I hope that you are able to get to updating this indispensable add-on very soon. I miss it every day - multiple times a day. Every time I press one of my "key combinations" to archive email - and then remember that it no longer works!

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
