Safari, a victim of his age?

But if there's one application that one might be tempted to apply this perspective, it's Safari. A French window all the more sensitive it is open to a world where hostility is not lacking. And then, Apple has fallen behind Google and its sensitive Chrome: it is fully designed to isolate processes from each other and HTML rendering extensions, is the concept of sandboxing, confinement in bins sand, literally.
Safari for Mac could give the impression to use the sandboxing for plug-ins like flash, but isolation is not complete - it is just there to prevent the component to crash the browser.

Mac OS X Lion could change somewhat the situation: a new process is associated with Safari, and it could be exclusively dedicated to rendering HTML, Safari Web Content (read: Safari 5.1: separate processes and WebGL). But it remains far from that Chrome isolates each tab in a dedicated process. And for Miller, Apple has "failed - or did not seek" to make regularly available for Safari updates made to its rendering engine, WebKit. As to better illustrate this assertion, Chrome has already enjoyed a patch for the vulnerability exploited in the last Pwn2Own to make him fall.
