No, you just authorize packet to port 80 and what happened to return
packet to have this working you have to add a rules using STATE, ie
accept all packet of the connection (and in particular response packet)
:
iptables -P FORWARD DROP
iptables -A FORWARD -m state --state ESTABLISHED -j ACCEPT
iptables -A FORWARD -s 0.0.0.0/0 -p tcp --dport 80 -j ACCEPT
