Review for Thunderbird Conversations by Neen
Rated 3 out of 5 stars
Removed this add on, until it saves conversations in drafts and you can check other mail while writing a reply (after losing one I'd spent an hour writing) I'm not using it. At the very least, a warning to alert you that you're about to lose your response would be nice. I'll come back then and buy you a beer.
This review is for a previous version of the add-on (4.0.26).To create your own collections, you must have a Mozilla Add-ons account.
