Do you think you know Facebook? It's more than just clever posts, fun selfies and crazy personalities. Kristina Guerrero has three awesome hacks that might just make you a social media star.

1.  See Who's Logging Into Your Account

Do you have a sinking suspicion that your ex (or mom) is logged into your Facebook account without your permission? You can find out. Go to your settings page, under the security folder you'll see the link "where you're logged in." You can see the browser, location, and even the device.

2.  Send Money

All you have to do is start a conversation in the "chat" window and hit the dollar sign. You can even do it through Messenger right on your phone.

3.  Block Browser Tracking

Remember when Facebook told us they started using our app and web-browsing history to show targeted ads? Yeah, we don't either, but they did it anyway. While you can't opt out of it, reduce the amount of info you share by downloading third-party ad blockers through the Digital Advertising Alliance.
