Rated 5 out of 5 stars

Neat add on. I've explicitly disabled updates of Thunderbird because newer versions don't work with this plugin. Mozilla doesn't seem to care about backwards compatibility.

This review is for a previous version of the add-on (1.2.5.2). 

You can update your TB now. Yet you still have to download the Add-on from my website ( see description ) in the meantime until The Thunderbird team approves the already updated and uploaded new version here on this page and sets it to 'public' so it will appear here too ...
