Hi. Sure, as soon as the mozilla community publish a full detailed info on "what has to be changed for the addons which used to work for years now could work again"... Besides this cynical comment, i'm currently struggling to find out myself with small hints i can find on the web, and i'm really struggling... So it is not garantuee. Cheers.
EDIT: TB v60 compatibility has been added in ARI v1.0.0.
I love your addon. I use it every day! Did you notice that TB will need a (partial) compatibility with webextension soon? (https://wiki.mozilla.org/Thunderbird/Add-ons_Guide_57). Will your addon be compatible? Thanks!
This review is for a previous version of the add-on (0.15.2).
