It depends how is it blocked...
If it is simple DNS block, you can overcome it either by getting IP from foreign DNS resolver or by manually putting static DNS entry
If facebook IP addresses are blocked, then you will need to route your traffic through foreign router, either directly or through some basic tunnel/vpn.
If it is blocked based on content/data, you will need encrypted tunnel/vpn so the traffic cannot be inspected.
There is no simple answer when conditions are unknown. It has definitely nothing to do with firewall or scripts.
