How is that a good idea? That kind of defeats the purpose of private browsing.
It's saying that cookies you set before you began private browsing will be active again when you finish looking at por.... err private browsing.

Apple just needs to kill this thing

You do know that Apple created WebKit (off of Konqueror, IIRC) which powers Safari, Chrome, Kindle, iOS, Android, webOS, and many other platforms, right?

Available for Windows XP but NOT Mac OS X LEOPARD ???

Are you kidding me Apple? Pathetic support, especially considering all the privacy invasion leak scandal stories involving Safari. :(

PS: The latest iTUNES is available for Leopard. Go figure.
