Great product, indispensible when having mulitple mail accounts and to segregate mail by subject.

Worked flawlessly until my Ubuntu 18.04 unexpectedly (apt-upgrade) migrated Thunderbird to version 115.18.0.

It perform beautifully without any problem and without duplications when executed from the All-Folders viewmode.

The Add-On does not work properly work if launched within Combined Unified Folders viewmode (where Inbox/Sent/Trash of accounts is combined to single view).
In this case the mail is duplicated as renamed to the new subject. ThereAfter both the original and renamed-duplicate mail can renamed without further issues.

Perhaps there's an internal conflict/acccess on/in folder-view mode.
