I've been using this extension for several years and it has worked flawlessly with the carriers preconfigured. Today I tried to add Royal Netherlands Post due to their miserable service and discovered the "Track Package Extension" web site with the explanation of how to add carriers no longer exists. The links for reporting problems and contacting the author are also broken. All extensions have their time and this one's time has obviously passed...
