Barence writes "Mozilla is proposing that the Firefox browser collects data on users' interests to pass on to websites. The proposal is designed to allow websites to personalize content to visitors' tastes, without sites having to suck up a user's browsing history, as they do currently. 'Let's say Firefox recognizes within the browser client, without any browsing history leaving my computer, that I'm interested in gadgets, comedy films, hockey and cooking,' says Justin Scott, a product manager from Mozilla Labs. 'Those websites could then prioritize articles on the latest gadgets and make hockey scores more visible. And, as a user, I would have complete control over which of my interests are shared, and with which websites.'"
This is the result of an extended experiment
. The idea is that your history is used to generate a set of interests which you can then share voluntarily with websites, hopefully discouraging the blanket tracking
advertising systems love to do now.
