It would be pretty optimistic to assume that Facebook wouldn't store your historical data, if you're deliberately logged in with your account but sending DNT: 1. Facebook's whole user experience pretty much relies on the historical data it collects of the logged in users' actions.

(I mean this from the point of view that you are a Facebook user who doesn't want to receive profiled advertising as described in the article.)

Thanks, but that's not what I meant to ask. There's a Firefox add-on that knows about about all the privacy-invading companies out there, and prevents Firefox from connecting to their servers.
