None of these will protect you if you're not using Facebook safely, though.
For starters, be careful what you post and what you look at on Facebook. Never post your full date of birth, address, phone number or any other revealing things about your life. Make sure your friends aren't posting that information, as well.
Speaking of your Facebook friends, don't assume everything they post is safe. They could be a victim of a scam or could have been duped. If you see a questionable post by them, ask them if they posted it. They may not even know it's there.
Try to ask them in person, if you can. Hackers taking over an account and posing as someone else isn't unheard of. If you ask them over Facebook while a hacker is in control of their account, you could be inviting trouble.
Would you know what do if a hacker took over your account? With a cool head and the right knowledge, you can take it back and stop it from happening again.
