Privacy has long been a thorny issue for Facebook: Three years ago, the social networking site unveiled its Beacon advertising project, which resulted in a class-action lawsuit. December's privacy changes aimed at encouraging users to share more information publicly evoked plenty of criticism. And this week at Facebook's f8 conference, Facebook announced even more changes that affect users' privacy.
Keeping track of Facebook's ongoing updates, upgrades and changes—and how they affect your privacy—can be confusing and frustrating. We've sorted through the new wrinkles for you. Here's a list of five essential privacy settings you should review now and tweak accordingly to ensure your information remains safe.
1. Facebook Privacy Settings: "Instant Personalization" and "Like" Buttons
What the "Like" button is: Facebook's big announcement this week from the f8 conference was the new "Like" button, which you'll start seeing on blogs and news sites across the Web. When you click the button on an external website, you authorize Facebook to publish your activity to your Facebook profile (which, in turn, will also be published to your friends' news feeds). Also, when your friends visit the external site, they will see that you've visited that site, too.
What "instant personalization" is: The second part to Facebook's announcements this week was it's announcement of "instant personalization" on partner sites, which (right now) include Pandora and Yelp. Without adjusting your privacy settings, when you visit these sites, they can pull in information from your Facebook account, which includes your name, profile picture, gender and connections (and any other information that you've made visible to the public). If you visit Pandora, for example, the site could also pull in your favorite music artists, create playlists accordingly, and then notify your Facebook friends.

How to change the privacy settings: The answer to the first part is easy—if you don't want your online whereabouts known, don't click any "Like" buttons.
The second part is more complicated. Click the "Account" option on your Facebook toolbar, then choose "Privacy Settings" and select the "Applications and Websites" option. At the bottom, you'll see, "Instant Personalization." Click "Edit Setting," then uncheck the box on the bottom of the page.
Note that unchecking the box will be enough to prevent partner sites from viewing your public information on Facebook, but when your friends visit these sites, your public information can be shared through them. To prevent this, you need to block the individual applications.
2. Facebook Privacy Settings: Application Settings
What it is: When you add Facebook applications to your profile, you agree to allow the application to access certain information in your profile. Sometimes this includes which friends can and can't view the application from your profile, and whether or not you give the application permission to post stories to your wall and your friends' news feeds.

How to change these privacy settings: Go to your "Privacy Settings" page and choose "Applications and Websites." Then, click the "Learn More" button next to "What you share." Follow the link at the bottom of the page that says, "You can view the full list of Applications you have authorized on this page."
Here, you can view which applications you are using, delete any you no longer use and edit the settings for each individual one.
3. Facebook Privacy Settings: What Your Friends Can Share About You
What it is: Sure, you may have painstakingly weeded through your privacy settings and think your information is secure, but much of your information can still be accessed through applications that your friends use.
For example, lets say your friend uses a greeting card application. This application can access the information you've made publicly available (such as your name, profile picture, gender, current city, networks, friend list and pages), unless you change your settings.
How to change this privacy setting: Go to your "Privacy Settings" page and choose "Applications and Websites." Then, click the "Edit Settings" button next to "What your friends can share about you." This page will show you all the options that your friends' applications can access. Check or uncheck them based on what you're willing to share.
4. Facebook Privacy Settings: Search Results
What it is: Do you know how searchable you are, both within the Facebook community and on the Web? This privacy setting is defaulted to create a public search listing so others can see a preview of your Facebook profile on search engines, such as Google. That means that when someone searches for your name, they'll see your Facebook profile picture, as well as any other information you've made public, such as your networks, friends, groups, and more. This privacy setting also determines how searchable you are on Facebook.
How to change this privacy setting: Go to your "Privacy Settings" page and choose "Search." There are two privacy settings you can change: your "Facebook Search Results," which determines who can see your search result on Facebook (you can set this one to everyone, friends and networks, friends of friends and only friends); and "Public Search Results," which you can allow or disallow.
5. Facebook Privacy Settings: Photo Albums
What it is: You may have set photos of you to be private, but what about your photo albums? Many people forget that the albums entitled "Profile Pictures," "Mobile Uploads" and "Wall Photos" are usually visible by everyone, unless you edit the privacy settings.
How to change this privacy setting: Go to your "Privacy Settings" page and choose "Profile Information." Scroll about halfway down, and you'll see the "Photo Albums" option. Click "Edit Settings." Here you'll see every one of your photo albums, and each of their assigned privacy settings.
Remember, you can choose the "Custom" option if there's a person or group of people you want exempt from viewing your album. And, if you're ever concerned that you've chosen the wrong privacy setting, you can view how your profile is seen by individual people. To do this, visit your "Profile Information" page of your privacy settings. At the top right corner is the option to "Preview My Profile." Enter in someone's name, and you'll see which parts of your profile are visible to him, and which ones are not.
