I didn't realize they could track you even when logged out. I only ever log into FB with Chromium Incognito mode, but apparently that's not enough.

I believe -and people can correct me if I'm wrong- the way they do it is through all the sites with integrated Facebook items: "Share this", "Comment" etc. The cookies they use to track you are sitting on your drive regardless of your facebook status (logged in/out) and can simply be retrieved the next time you log in or link accounts.

  So they can track your visits to any site with a FB Like or Share button on it, but only when you next login to FB?

If you log in with incognito mode, the cookies created in that session will be deleted at the end of that session (when you close your last incognito window) and will not be available to non-incognito browser windows.

  Right, that's what I thought was the reason FB can't track you outside of Incognito mode, but if they can track you even when you're logged out of FB then it sounds like it's irrelevant whether you're using Incognito or not.

    If I remember correctly, the way they track you is that they retain certain cookies that identify you even after you log off. But if you delete all the cookies you have from FB once and then delete any new cookies you get from them after each session (via incognito mode), wouldn't that fix the problem? I suppose that they could also track you by IP address, but that would be pretty unreliable since most home users have dynamic IPs. If you really want to avoid tracking, you can use a browser extension like NoScript (or the similar NotScripts for Chrome) to prevent the JavaScript code that puts their buttons on third-party web sites from loading.
