I have |browser.newtabpage.enabled |and browser.newtab.preload both set 
to false.  Several Fedora-related DNS lookups still happening. 
(Parentheses in that script output mean the lookup returned a CNAME.)

        Right now, I have the following list for Firefox on Fedora. The
        one site I'm visiting is blog.zgp.org which has no 3rd-party
        resources on it. All the rest of the DNS lookups are the browser
        and/or Fedora.
