Fix for Facebook Chat - Show only users online

Since Facebook changed its chat I hear a lot of people complaining that they prefer the old chat where you could see only your online friends and not those that Facebook decided you should see even if they aren't online. Here is an intresting *fix*. I've tried multiple extensions and this is by far the best one I've come across.

Just install this script: Online Users Only in Chat

for firefox you have to have greasemonkey installed.
