What’s Not Included in Facebook’s “Download Your Data”

A simple test suggests otherwise, using Gruez's recipe above but swapping the private and non-private windows.

There are potential information leaks, such as the combination of IP address, user agent, screen size, and fonts available. And there may be bugs in 3rd party plugins like Flash that fail to respect private mode. But it doesn't seem to be anything as simple as cookies being shared.

Thanks. If they're not using the temporary cookies folder, I'm curious how Facebook shows ads based on incognito browsing. Some form of device fingerprinting?
