I love this add-on! Unfortunately, it (version 3.2.0) has stopped working on my copy of Thunderbird 52.9.1 (32bit). I tried going back to the previous version of DragAndDrop, but that didn't work either. There must be something in the newest Thunderbird version that is affecting the add-on. I am on the "release" update channel and 52.9.1 is the latest version as of today (2018-07-20).
Uninstalling & re-installing twice seems to have fixed whatever-issue-it-was. Happy again!
