How can I really make my Facebook profile private to people I'm not friends with?

[Empire539]

In your privacy settings, try the following settings (if they're not already set to those values):

In "Privacy" > Who Can See My Stuff > select "Friends"
If you want, you can also choose to "Limit Past Posts" so that any posts that were previously Public or set to Friends-of-friends will be set to just Friends.

In "Timeline and Tagging" > Who can see things on my timeline? > Who can see what others post on your timeline, select "Friends"
> Who can see posts you've been tagged in on your timeline, choose "Friends" (or a tighter setting)

Note that you can use the "View as" function to view your profile as a public person, or as another friend.
