    I asked myself the same question!
    dpkg -c gives for me the same result, but here is the install output

    ->> apt-get install -t jessie-backports firefox

      If this is not a bug, how do you explain that?
      I also tried with aptitude, and got the same result.
      I suppose that the link is not actually in the package, but is set by the
      post-install script, which may be the culprit
