You can could use a helper application in your browser (Mozilla in this case)
application/x-sh /bin/bash

Put test script on web server far away

cat /etc/hosts > /tmp/test.txt

When you browse you will be asked how to open it
enter /bin/bash
Click Always open with this application

Then in a shell on you local machine
cat /tmp/test.txt and you will find your own hosts file :)

You can look what you have done to your prefs.js after you close the browser

Kinda dangerous but you could do some interesting things.
Take care where you go.
