This fixed a problem I was having with Thunderbird since the latest update. Each time I started Thunderbird, I was getting tabs from an old session. Even though I closed those tabs after the startup, they kept returning with each new startup. So, I installed this add-on and the old tabs stopped opening. It fixed my problem. I don't know if there are any other reasons for this add-on, but it worked for what I needed it to do.

It does its job, but has a side effect/bug: I do not want the message window to appear - ever. In session I can disable it all right with F8, but after TBird restart it is back.

Très utile pour les personnes aveugles car il permet de fermer tous les messages déjà ouverts et d'arriver directement au dossier "courrier entrant".This review is for a previous version of the add-on (1.1.1).
