I've updated my MacBook from MacOS 14 to 15.1.1 and it seems various add-ons are not working in Thunderbird including CardBook and Mail Merge. Others like XNote++ and Send Later do seem to be working. I've checked for updates to the add-ons. I'll get in touch with their developers as well. Has anyone else experienced this?
