There is definitely a leak in the heater core. The hose that you mentioned which comes out of the firewall on the pass. Side of the car is actually an evaporator drain tube, which is used to remove condensation from the heater/A.C. Box when the A.C. Is on, and because your heater core has failed and is filling the heater box with antifreeze the tube is allowing the coolant to drain onto the ground. I suspect that if you feel around on the floor of the passengers' side of the car the carpet will be wet as well, this is proof positive of heater core failure.
