Steps to reproduce:

Actual results:

This one loads is malicious code from a .xul file to invoke an XHR call to get http://74.81.91/[.]227/~radioour/oi.txt

what's interesting is that it waits 1 sec to inject the contents of oi.txt and has a separate call to re-inject every 600 secs

oi.txt (packed):
