    Bug 22457: Allow resources loaded by view-source://
    
    Instead of whitelisting single resources for view-source requests that
    might allow platform detection we allow all of those that are needed by
    requests with a view-source origin. This should be safe now that
    https://bugzilla.mozilla.org/show_bug.cgi?id=1172165 landed.
