Ce module semble bien sympathique. Ce serait parfait s'il pouvait aussi synchroniser la carnet d'adresses de Thunderbird avec celui de Yahoo! Est-ce envisageable (je n'ai aucune connaissance technique à ce sujet) ?
This review is for a previous version of the add-on (0.8.13).vivakvo, it would be possible to extend the addon to include sync with yahoo. A few people have asked for it. But there doesn't seem to be a huge demand for it.
