TancaComentari del Remove Duplicate Messages per Sergio3N
Rated 4 out of 5 stars
Beautiful extension, but in Thunderbird 78.2.0 (Italian version) I have a problem : when I activate the plugin it adds a button on the message bar.
If I remove the button, the button reappears the next time Thunderbird is restarted
