keep an eye on your facebook friends movements
Followbook is a little but effective extension.
With Followbook you can search for your friends stories in the activity stories bar in facebook(which appears above chat bar).
How does it work ?
You simply type your friend name (or a part of it) and click the search button , it searchs for 5 seconds for his stories , it brings up his stories so you see them at the top , you may also click many times to bring more stories ...
* Some of your friends stories may take a long time to move to the top , it's because they appear at the very bottom , all depends of how facebook chooses which of your friends to show in the activity stories.
