How do I block Facebook without breaking web surfing?

[Walter Dnes]

  Out of a bit of paranoia, I'm blocking Facebook and its "Like"
buttons, on my machine.  Here are 3 snippets from my iptables rules

-A INPUT -s 69.63.176.0/20 -j FECESBOOK
-A INPUT -s 69.220.144.0/20 -j FECESBOOK
-A INPUT -s 69.63.176.0/20 -j FECESBOOK
-A INPUT -s 69.171.224.0/19 -j FECESBOOK
-A INPUT -s 69.171.224.0/19 -j FECESBOOK
-A INPUT -s 96.16.0.0/15 -j FECESBOOK
-A INPUT -s 200.58.112.0/20 -j FECESBOOK
-A INPUT -s 213.155.64.0/19 -j FECESBOOK

-A OUTPUT -s 69.63.176.0/20 -j FECESBOOK
-A OUTPUT -s 69.220.144.0/20 -j FECESBOOK
-A OUTPUT -s 69.63.176.0/20 -j FECESBOOK
-A OUTPUT -s 69.171.224.0/19 -j FECESBOOK
-A OUTPUT -s 69.171.224.0/19 -j FECESBOOK
-A OUTPUT -s 96.16.0.0/15 -j FECESBOOK
-A OUTPUT -s 200.58.112.0/20 -j FECESBOOK
-A OUTPUT -s 213.155.64.0/19 -j FECESBOOK

-A FECESBOOK -j LOG --log-prefix "FECESBOOK:" --log-level 6
-A FECESBOOK -j DROP

  That works.  However, I've recently started running into a lot of web
pages that simply refuse to load under Firefox+Opera with those IP
addresses blocked.  w3m works on them, so I assume this is related to
graphic elements, i.e. the "Like" button, or "Follow" links.  Any idea
how I can block those ranges without webpages refusing to load?
