Remember there is a second scroll option on the page; to scroll down your online friends. Don't be mistaken by thinking that Facebook shows offline friends too, because it doesn't.
At the top of your online friends list it will show friends you communicate and interact with on a regular basis, however, further down, the list shows online friends, that you communicate and interact with a little, or even not at all.

If your Facebook is simply not working, and you know this for sure. I would recommend, firstly restarting your computer, if the problem persists, try another internet browser.
