Rated 3 out of 5 stars
Unfortunately this addon still does not work with Thunderbird 68.1.1 winmail.dat still appears....This review is for a previous version of the add-on (2.0.0).
I have had the odd report where the add-on update wasn't working. Please try removing, restarting and closing the add-on panel and then manually re-install the add-on. For further support please open an issue on the support site
