I have the bit set to clear cookies when I close Firefox. When I reopen, quite often , besides the default google cookie (due to home page) but one or two of the cookies from the previous session. This is disturbing :)

Are you reopening tabs from the previous session automatically?

In that case cookies from these tabs are stored in sessionstore.jsonlz4 as part of the session data.
