Contact Tabs does not function properly anymore with TB 45. It was OK with TB 38.This review is for a previous version of the add-on (2.0.12).
EDIT: Version 2.0.13 is up and fixes this problem.
Contact Tabs currently does not work with Thunderbird 45. I'm a bit short of time at the moment, but be assured that I'll try to fix it.
