Rated 3 out of 5 stars

The extension looks great but has a serious annoying problem that I have no idea how to remedy.I've read the reviews, I've read the faq's I've not seen this anywhere and I have no desire to open a github account to post an issue or bug.Here is the issue explained and show in a video.http://youtu.be/pRPDIdScbn0The video is unlisted and will only be seen via this thread.

Thank you for the reply.

This review is for a previous version of the add-on (2.5.2). 

This is a bug in the Thunderbird code that surfaces badly in Conversations: see https://bugzilla.mozilla.org/show_bug.cgi?id=646225 for all the details (this is the faq item called "a message is grouped with another unrelated conversation"). Unfortunately, there is no fix in sight.
