I hope this add-on can be updated for TB 78.2 (which is an add-on nightmare - lost 80% of the add-ons I was using). When you need this function, you really need it and nothing else will do.
I'm working on it... but if you need this function, for now, you'll have to disable auto updates and download and reinstall Thunderbird 68.* again. At first start, you must run it with command line option --allow-downgrade
