Nuovo rilascio per Firefox, il browser di casa Mozilla che con questo rilascio arriva alla release 19. La novità principale di Firefox 19 (o meglio l'unica) è la presenza del lettore PDF integrato, lettore che in verità era già possibile attivare dai settaggi avanzati nella precedente versione, ma che ora giunge preattivato e nella versione finale giudicata adatta all'uso di tutti i giorni.
