Hi Eyal,

I would agree with your assessment as to what is happening here. Kind
of makes sense. The PB window creates an alternate cookie etc. store
and doesn't share that with your main session, or with other PB
sessions, but will retain it until the PB window is closed.

You do need cookies to work, even within a PB session, otherwise you'll
break the web.

Whether that PB cookie etc. store exists on disk or in memory, I don't
know (but it's all open-source, so we could take a look...).
