Rated 4 out of 5 stars

It is a wonderful add-on but not work with thunderbird 50, make the thunderbird broken. Pls update.

This review is for a previous version of the add-on (3.0.2). 

This was a bug in Thunderbird and should be fixed in TB 50.0b3. See this bug for more details: https://bugzilla.mozilla.org/show_bug.cgi?id=1302478
