Facebook chat is such a cool 'tools' by Facebook webmaster that allows you to send instant messages straight to your online Facebook contacts.
Eventhough I'm not really a fan of the chat bar being at the botton of the page, then what if I've left Facebook?
But at the same time, I want to remain chatting with my Facebook contacts? Have you face this kind of situation?
Me, YES!!. I did!! Then, the alternative is, by using Firefox. You can place the Facebook Chat at the sidebar.
You are done!! Enjoy!!
