First of all, you have to make your cable modem, wireless router and operating system secure. If you have security vulnerabilities here, your FB account will never be secure.
If you aren't ready for these steps, move to the Facebook account settings of this article.
Starting with the cable modem, set it up for bridge mode or DMZ host. This will keep the cable company out of your network altogether. Many cable companies have opened up their firewalls to the Motion Picture Association of America and the Recording Industry Association of America who can easily monitor any movies or songs you or your family download from point-to-point (P2P) networks like torrents.
Then upgrade your router or uy a router that is compatible or DD-WRT firmware on it. This third party firmware will keep the local and state police out of your wireless network as long as you use at least a 12 to 16 digit wireless password with upper case and lower case letters numbers and special characters such as Randumpasw8rd!. Turn off WPS and WPA security. Only use WPA2 security with AES encryption. Do not use any pins for quick wireless access except on a short time basis like a weekend OFA rally.
If you can, do no use wireless at all. Use a wired Internet connection or a powerline adapter that runs over you electrical system. I have had very good luck with the Netgear Powerline V200 adapter and even run NetFlix using one.
You may have to hire someone to configure the router and the cable modem.
Microsoft has many unadvertised vulnerbnabilites and backdoors and NSA is well aware of them. Do not use Microsoft Windows for browsing the Internet. Try Linux. Centos 6 is the best release Rightrdia has seen to date. We also like Linux Mint. Make sure you apply all of the security patches after installation and enable the firewall. There is also a free anitvirus program called Avast for Linux that we recommend. See http://www.avast.comu/linux-home-edition
Update: Also, use the Linux search engine, Duck, Duck, Go (DDG) instead of Google or Bing. DDG uses the secure protocol HTTTPS for searches and does not archive your searches either. Law enforcement will not be able to recover your search data.
If you recall the Casey Anthony case, the prosecuting attorney suggested that Ms. Anthony had searched on the Internet for instructions on howto make chloroform. Rightardia thought this assertion was implausible.
Now that you have hardened your network . . .
Onto to Facebook
First look at your account settings | Security
Make sure that secure browsing is enabled. You may want to enable login approvals if you are using a browser other than Chrome. Apps like Xbox, Spotify and Skype can also be given app passwords. These are additional levels of security.
Your Privacy seeing must be done correctly or you will have serious problems. However, the more restrictive you make privacy, the smaller your FB circle will be.
Custom has some extra options:
You can select only friends Friends of Friends or a use a list Notice you can also disable sharing from your posts that are tagged. You also have a blacklist option: Don't share with these people or lists.
Please note some other important options:
Also, start using blocking to rid your FB account of pests, trolls and Lotharios. You can block app requests, event invites and app invites.
In summary you must make your home network and PC secure in order to make FB secure, You must make a simple change to your cable modem, a complex change to your home router that may require a new DD-WRT compatible router; and also make your wireless network more secure. Disable wireless access if you can browse over Ethernet: wired or powerline.
Update 2: Now you need to install Virtual Private Networking (VPN) software on your OS. fFnd a VPN service that has servers in Canada. The Canadians will to respond to any US John Doe subpoenas from law enforcement. Recommend Private Tunnel OpenVPN or BTGuard.
Once the VPN is up and working, you will be browsing over a encrypted Internet tunnel with a Canadian IP address. You will be invisible to the local and state law enforcement agencies.
