TB 68.3.0 in macOS 10.13.6. Can't find the preference window in Tools/Add-on/Preferences.
The workaround is to use the config editor or add the Remove Duplicate button into the toolbar.
It seems to detect the duplicated message. But as a previous reviewer pointed out, I can't find the preference menu in either Thunderbird/Preference nor in Toos/Add-on Preference.
