I would use the following construct:

class GeneralBehaviour
def initialize
start_browser
login

specific_behaviour

...
end

# this is only necessary if GeneralBehaviour can be used
# on its own
def specific_behaviour
end
end

class SpecifB1 < GeneralBehaviour
def specific_behaviour
# do sth specific ;)
end
end
