Great, except for popup Noté 4 sur 5 étoiles

This extension is great, but I am wondering how to turn off the annoying “You have no items in your list!” popup when removing the last entry by clicking the URL bar button. Is there a way to do that?
I already know how to use the extension, so for the instructions to keep popping up when you read the last entry is just an annoyance.
