Adil,

Since FB is using HTTPS there is no way to block it with url matching. The URL 
is encrypted.
All you can do is to block based on IP which can be difficult and not reliable.

It could be possible using FPM on the routers by matching CN in the certificate.

Other option in real life is to have ASA-CX :)

Regards,
Piotr
