"""Unit tests for the Firefox-family cookie helper error branches.

``_read_firefox_container_cookies`` maps every extractor failure to a typed
:class:`~notebooklm.cli.services.login.outcomes.BrowserCookieOutcome` carrying
the friendly message; the command layer (or ``refresh._exit_on_outcome``)
renders the message and exits. These tests pin the four terminal error
handlers (each returns an outcome whose ``message`` carries the original
text) and the early return in ``_maybe_warn_firefox_containers_in_use`` when
no profile is found.
