How to Follow/ Unfollow all of the Facebook friends at once?

Hi guys, today I am going to share some tricks regarding Facebook. I had unfollowed all of the my Facebook friends but doing this I restricted myself from seeing my friends post. So I decided to follow them back. I have lots of friends on the list so it is tedious to follow all of them one by one. So I wrote few lines of JavaScript which I want to share with you here on my blog. This works for Facebook new layout.

Lets get it done:

step 1: Go to Newsfeed preferences from the dropdown menu.

step 2: To mass Unfollow.

            i.   Click on  Unfollow people to hide their posts.
            ii.  Select who you want to unfollow from drop down menu.
            iii. Scroll to the end.
            iv.  Open Console menu ( In chrome: Ctrl + Shift + J)
            v.   Paste the Code Given Below:

    var buttons = document.getElementsByClassName('_5u3n'); for(var i = 0; i <=                       buttons.length; i++) {buttons[i].click(); console.log("friends followed=", i+1);}

Step 3: To mass Follow:

            i.   Click on Reconnect with people you unfollowed.
            ii.  Select who you want to follow from drop down menu.
            iii. Scroll to the end.
            iv.  Open Console menu ( In chrome: Ctrl + Shift + J)
            v.   Paste the Code Given Below(same code as above):

  var buttons = document.getElementsByClassName('_5u3n'); for(var i = 0; i <=                        buttons.length; i++) {buttons[i].click(); console.log("friends unfollowed=", i+1);}
