Most of us now pissed off with the latest 
Facebook chat
 sidebar . It is quiet annoying because when scroll down to Facebook page it shows up in the right side all the time and in the chat 
bar it 
shows up all the 
 friends you recently had chat whether they are 
online or not. I have got solutions for the people , who don't want to see this latest sidebar chat  
box  in Facebook. 
Solution 1: (partially operational)
Just go to your Facebook profile :
Then press Ctrl + for two times or, by pressing Ctrl scrolling up with mouse scroll ( if it is available in your mouse), thats it. See below what happens:
limitation : in this trick it will show up like old chat but functions like new chat system.
Solution 2: (Fully operational) 
In this 
tricks  you have to do nothing but install a add-ons for your browser, and guess what you are ready to have your fully functional old Facebook chat.
