It was awesome but stopped woking now(Thunderbird version 52 and above). Hope the author is working on it.

This review is for a previous version of the add-on (2.11.4).

Thanks for the comments, we've just released a new version that is compatible with TB 52. You should be able to update to it by going to Tools -> Addons and selecting the Cog symbol and "Check for updates"
