Rated 5 out of 5 stars

I have been a happy user of copysend2current for many years. But now after a Windows 10 reinstall and adding copysend2current anew I can't get the dialog to pop up when I send a message. Any hints what may be missing?
I'm using Thunderbird 60.0 32 bit under Windows 10.

This review is for a previous version of the add-on (1.2.1).
