Mozilla Firefox 3.7 Alpha 5 disponible

Comme prévu dans le planning de sortie de Mozilla, voici la 5ème et (peut-être) dernière alpha sous la numérotation 3.7. La suite pour les développeurs serait d'attaquer la phase beta et d'enfin renommer la branche de développement en "Firefox 4.0".

Firefox 3.7 Alpha 5 arrive avec quelques nouveautés dont le support du WebM, le nouveau gestionnaire des extensions, la possibilité d'avoir les onglets au-dessus de la barre d'adresse et l'arrivée des versions 64 bits de Firefox pour Mac et Linux.

Voici les nouveautés en détails :

Gecko 1.9.3 alpha introduces new features which can be tested by using this Mozilla Developer Preview. Many of these features are still in development, and while they will likely appear in some future version of Mozilla Firefox, some may be in earlier releases than others.
