Being able to enable this on a per-tab basis is important as well. When in this stealth mode, browser and download history is not saved and cookies are deleted when the tab is closed. There should be some visual to indicate private browsing as well. More than one instance should also work for example so that a user could sign ento three accounts of the same service simultaneously. This is still lacking from Chromium and Firefox.
