Comment (by mcs):

 Kathy and are working on this.  Our current thinking is that we will
 modify nsHttpChannel::BeginConnect() and nsHttpChannel::DoAuthRetry() to
 suppress the Authorization header when the request is a third party one.
 That approach will keep the behavior consistent with what is implemented
 by Torbutton's stanford-safecache.js code today.

 We will use methods from ThirdPartyUtil to determine if the request is a
 third party request.  We may need to whitelist requests whose parent is
 "chrome://browser/content/browser.xul" to allow for authenticated favicon
 requests (as is done in stanford-safecache.js).
