I was finding a way on how to unlike all the pages on Facebook at one go. After trying some different things out in console and looking at some chrome extensions, I figure out with just some commands you can unlike all the pages at one go. Here’s how to do it.
Firstly go to Likes section in your profile under your cover photo. Here’s the snapshot help:
Click the Likes link. And you will be redirected to the the likes page.
Then right click on your page anywhere and click inspect link in the menu. It should open a section beneath or on the sides on your browser.
Something like above. Click console in that and you should find a big warning saying — “STOP”. Ignore that. (Trust me! :D)
Now write this commands as listed below:
// Get hold of all 'Liked' Buttons
var buttons = document.getElementsByClassName('PageLikedButton');
