Rated 4 out of 5 stars

Reporting of multiple messages doesn't work since the latest version (Thunderbird 78 compatibility release). Also it would be nice to have a button for this similar to the single message reporting button, instead of having to go through the context menu.
(Sorry for the English rather than French.)

This review is for a previous version of the add-on (4.0.4). 

You should have two buttons, one in the main toolbar and one in the message toolbar (once you have opened an email or in the preview panel).

You can report multiple emails, at least you should be able to.

Have you customized the toolbars?

If you can provide screenshots as well as your OS version and if you have specific extensions installed, so that we can check the same environment.

TB78 is quite recent and may still have some bugs...
From our tests, the reporting of multiple emails works fine on MacOS and Windows with TB78.2.2 or 78.3.1.
Sorry we can't add any screenshot here... Please contact us by emails.

Thanks (english is also supported :-))
