# Define a derived domain for the mozilla/mozilla program when executed by
# a user domain.

# The type declaration for the executable type for this program is
# provided separately in domains/program/mozilla.te.

# FIXME: Rules were removed to centralize policy in a gnome_app macro
# A similar thing might be necessary for mozilla compiled without GNOME
# support (is this possible?).
