[aeternus]

This is similar to what I'd like to see. Sharing cookies is somewhat dangerous since they could have login/user data, but it would totally work to avoid browser fingerprinting. With all the fingerprinting methods (screen resolution, GPU, HW, font-list, etc.) it's a losing proposition to attempt to remove all traces of a unique fingerprint.

Instead I'd like to see a browser that generates such a noisy fingerprint that it is useless: Each time I start an 'anonymous' session, grab a fingerprint from a pool that is sufficiently similar to mine that things render properly (matching resolution for example) but that has also been used by thousands/millions of others.
