You are a genius. This add-on really gives my Thunderbird the Gmail conversation view. The only issue is that I can't figure how to open the messages in windows instead of tabs (even after I choose "open messages in a new window" in TB options).
In any case, thank-you very much for sharing this.
Opening a conversation in a new window is a indeed something that does not work with the current version. It would require a fair bit of work to make it happen; I'm doing this on my free time, which unfortunately means I can't afford to work full-time on this; so unless someone steps up and contributes a patch, there's little chance that opening a conversation in a separate window will work anytime soon, unfortunately.
