I'm trying to setup firewall policy to block some websites like facebook.com and youtube.com.
My setting is the same as mentioned here http://kb.juniper.net/InfoCenter/index?page=content&id=KB4320 . But facebook and youtube are still not blocked. Please advise

Did you position the policy at the top of all Untrust policies? At least for test it is best to do so. As soon as it works, you can relocate it to a more appropriate position, but before any "Deny all" policy you might have defined.

Another possible failure reason is that Facebook and YouTube use more than one IP address, and the DNS resolution of Juniper does not take all IPs into account.

I dont think juniper firewall can do it ....
need websense device or some kind of proxy to do it ...

or else you should know all IP used by youtube & facebook and put rule accordingly..

Facebook, YouTube and the like use several different IP addresses, based on where you are located (and several other criteria). Blocking "www.facebook.com" in a policy is indeed not working for that reason. Common ways to perform reliable blocking:
creatie fake DNS entries in your main DNS server. That is, create a zone facebook.com with an entry named www, having 127.0.0.1 as IP. And bang!, www.facebook.com cannot be reached anymore.
use WebSense or SurfControl - both require a server you can connect to to decide which criteria are applied for blocking, and some licensing (IIRC).
Set up a Web Proxy at your LAN, and only allow HTTP connections from there. The Proxy server then can decide which traffic is allowed.
