Subject: Starting program from custom page 
Just in case anyone needs this in the future I am adding a comment about this issue. After a few months of working
with this solution we noticed that when using

request.open('GET', url, false);

on firefox it could cause the javascript to stop at that point, possibly due to a delayed response from the
server. A simple solution is to send an asynchronous requests

request.open('GET', url, true);
