Relevant to the work of this Working Group
I guess it relates to ISSUE-10: What is a first party? [2]

    Dave Winer wrote a timely piece this morning about 
    how Facebook is scaring him since the new API 
    allows applications to post status items to your 
    Facebook timeline without a users intervention. It 
    is an extension of Facebook Instant and they call 
    it frictionless sharing. The privacy concern here 
    is that because you no longer have to explicitly 
    opt-in to share an item, you may accidentally 
    share a page or an event that you did not intend 
    others to see.

    The advice is to log out of Facebook. But logging 
    out of Facebook only de-authorizes your browser 
    from the web application, a number of cookies 
    (including your account number) are still sent 
    along to all requests to facebook.com. Even if you 
    are logged out, Facebook still knows and can track 
    every page you visit. The only solution is to 
    delete every Facebook cookie in your browser, or 
    to use a separate browser for Facebook 
     Logging out of Facebook is not enough, [1]
