Flash player(common denominator for all browsers) still runs in separate system process, so I does not look like overall security of web increased at all. That's not big suprise tho, if you are required to have Adobe Flash player installed in order to use Youtube. There is also entire advertisement ecosystem built by Google, which relies on flash player... and I don't mean ads here, but all the data about users which Google is harvesting through it thanks to Google Toolbar which is bundled with Flash player.
