  wget http://users.tkk.fi/~otsaloma/art/firefox-form-widgets.tar.gz
  tar -xvzf firefox-form-widgets.tar.gz
  su
  cp /opt/mozilla/lib/firefox/res/forms.css /opt/mozilla/lib/firefox/res/forms.css.bak
  cat firefox-form-widgets/res/forms-extra.css | tee --append /opt/mozilla/lib/firefox/res/forms.css > /dev/null
  cp -r firefox-form-widgets/res/form-widgets /opt/mozilla/lib/firefox/res
  rm -rf firefox-form-widgets*
