Where is the persistent storage location for inprivate "session" cookies stored? For example, I sign into instagram.com in a private window my session is stored in a persistent cookie but this cookie does not appear within the cookie manager. about:preferences#privacy > manage data. I realize the cookie is dumped on private session close... How would I access my private session cookies? I don't believe they are stored in a .sqlite table is there a way to access them within memory? How does firefox access them? Thanks.
