      Gnuzilla is the GNU version of the Mozilla suite, and GNU IceCat
      is the GNU version of the Firefox browser.  Its main advantage
      is an ethical one: it is entirely free software.  While the
      source code from the Mozilla project is free software, the
      binaries that they release include additional non-free software.
      Also, they distribute and recommend non-free software as
      plug-ins.  In addition, GNU IceCat includes some privacy
      protection features.
