I just cleared my cookies...oh, wait...I missed some!

I'm not one of those uber-paranoid people that wipes out my cookies each time I close my browser. Quite frankly, I just don't care that much.

But little did I know, that little "Clear Cookies" button can miss a few here and there.

According to this article it is possible for websites to use Flash-based cookies to track you, and they aren't cleared out with the normal button.

You actually need a Firefox Add-on like BetterPrivacy, or even an extra application like CClearner.


Yet another bit of proof that the best way to ensure security is to not rely on the "comfort" of the Erase button.
