 If a zero day JavaScript exploit is able to compromise Firefox,  it may be
 able to override TBB’s Settings.  If it overrides the default homepage
 setting, every single time the user opens TBB  it will open up a possibly
 malicious homepage.  In attacker may be able to do much worse if they’re
 able to TBB  Preferences.  A simple way to solve this would be have the
 sandbox launcher reset the settings every single time tor browser starts,
 adding an option for users to opt out my also be useful.
