How to install Old Facebook Chat UserScript
Go to http://userscripts.org/scripts/show/107159 and click on Green button saying “Install”.
For Firefox users, you must have GreaseMonkey addon installed to install this. For Google Chrome however, it is installed directly and activates automatically on opening Facebook.com
Note: This Hack doesn’t activate Old Facebook Chat for your Account but only when you access Facebook from the browser where script is installed.
