When run in read-only mode, FFP keeps your profile in the local machine's temp directory. In that, it created FirefoxPortable\profile and keeps it there. It is deleted as soon as you exit Firefox. You should configure Firefox to your liking *before* burning it to CD. Once burned, no changes are saved between sessions.
