This is a great add-on (since Thunderbird removed Dropbox as a filelink provider for large attachments) and worked well until Version 52 (?). It now is not compatible any longer with version 60. It would be great if the developer could make the necessary adjustments to the add-on, so that it is Version 60-worthy! Thanks in advance.
