you can use opendns filtering or filter https protocol allowing only known https sites

you cannot filter https traffic because of encryption obscure url text

The only way to do that with a DFL firewall is to block the HTTPS traffic to the domain ranges used by facebook:

After that, create a group that contains all those objects

Create a block rule before all the other rules and that should prevent the access to facebook.

Here's a suggested list of IP adresses:
