How to Deactivate/Remove/Disable TIMELINE in FB

Lately, I was trying hard to figure out how to get rid of timeline. Its not because I don't like it, but my friends asked me to remove from their FB. Well, I tried going through developers site of FB but it didn't work. I was suppose to get the "edit apps" option on the "Apps" tab of my FB profile, but alas! nothing was there. So, I did a little research and figured out the most easiest way to get rid of the Timeline and make it reappear as and when I need.
So friends, Please follow the following procedure for the Firefox browser to get rid of Timeline.
