The answer is cookies. Facebook sets multiple cookies on your browser that do not expire and are not deleted when you logout. By logging in at work and home, you are making it trivial for them to track you. They also set this cookie when you intract with a Facebook like, share, comment or use Facebook to log-in to a third-party site. A few suggestions to help mitigate this: - Use a browser dedicated to all your social media browsing and another browser for everything else. Say Firefox for Facebook and Twitter, and Chrome for everything else. That will restrict what they can capture. - Browser Facebook in your browser's incognito it private mode. - Minimize third-party links you follow from your Facebook timeline. And don't shop and Facebook in the same browser! - Don't interact with Facebook outside of their actual site. This includes likes and comments. - Don't use Facebook as your log-in credential. - Use an ad blocker! - Have your browsers delete all cookies on log out. This is both your day-to-day and social media browsers. Facebook is not the only media company tracking you.

i assure you, that you can still be tracked without cookies. It's not as easy, but it's definitely possible to fingerprint a browser and track its requests to a server even if there aren't cookies. The level of confidence will be good enough for advertising.

  Indeed. Which is why I like to use a separate browser for social media. Having said this I know it's a losing battle, but I see no reason to make it easy on the bastards. (I've worked in ad tech in a previous life)
