Rilasciato Firefox 18.0 con IonMonkey

Gennaio 8, 2013 Marco Giannini

Il team di Mozilla ha quest’oggi rilasciato Firefox 18.0, la nuova versione del browser del panda rosso. La novità più sostanziosa di questo rilascio è la presenza di IonMonkey, il nuovo motore javascript che ne velocizza ulteriormente le performance. Altra nota positiva è l’introduzione del supporto (preliminare) a WebRTC. I possessori di Mac con Retina Display e OS X potranno poi beneficiare del supporto a questo tipo di schermi.

L’aggiornamento a Firefox 18 verrà notificato nelle prossime ore, gli utenti Linux che non vogliono usare i binari dovranno aspettare l’aggiornamento dei propri repository.
