I *really* appreciated this add-on, and sympathize with the annoyance of breaking changes introduced in TBird 68. I agree with others who suggested that this be migrated to a paid add-on to fund work to migrate it to TBird 68+; I'd pay for it! NOTE that there is now a more detailed migration guide at https://developer.thunderbird.net/add-ons/tb68 which looks like it'd eliminate the guesswork needed to migrate - still annoying that so many breaking changes were introduced to TBird.
