Hints

• asv-url-not-secure
  org.gnome.font-viewer.appdata.xml:229 - http://www.gnome.org/gnome-3/
  Consider using a secure (HTTPS) URL for this web link.
• asv-nonstandard-gnome-extension
  org.gnome.font-viewer.appdata.xml:239 - kudos
  This tag is a GNOME-specific extension to AppStream and not part of the official specification. Do not expect it to work in all implementations and in all software centers.
• asv-cid-contains-hyphen
  org.gnome.font-viewer.appdata.xml:3 - org.gnome.font-viewer.desktop
  The component ID contains a hyphen/minus. Using a hyphen is strongly discouraged, to improve interoperability with other tools such as D-Bus. A good option is to replace any hyphens with underscores (`_`).
• asv-url-not-secure
  org.gnome.font-viewer.appdata.xml:231 - http://www.gnome.org/friends/
  Consider using a secure (HTTPS) URL for this web link.
