Great add-on.
Can someone contact the developer for an updated version? It cannot work in TB5. Though I have installed Thunderbird conversation, I would like to have it as well.
Thanks.

This review is for a previous version of the add-on (2.1.685).

I just posted an updated version, it's still in the review queue and should show up within the next few days. Alternatively you can download the newest version from the add-on's homepage at http://threadvis.mozdev.org/
