It will be interesting if this actually works out worse for privacy; say the site decides instead to remember you (for ad purposes) by ip address instead of by cookie, so everyone from that ip address ends up in the same profile target.
e.g. i visit a website to buy a birthday present for my wife, but later everywhere she browses she suddenly sees adverts for the shop or product that i bought.

It only really falls down when there are a large number of totally identical machines in the same IP range, where the machines are locked down so plugins (etc..) cannot be installed. E.g. a large office or university lab.
