 Usage
  - Go to https://www.instagram.com/instagram_handle/ (change instagram_handle in i.e. taylorswift)
  - Open up the console (F12) (Firefox users: type 'allow pasting' if you haven't done so yet)
  - Select the contents of this complete file and copy/paste it to the console and hit enter
  - You may close the console now
  - A UI pops up at the left, click on the button to start scrolling
  - If you scroll with the mouse, the autoscroll stops

Thanks for the script. How do I make it work for just instagram followers.
That is
Go to https://www.instagram.com/instagram_handle
Click on 67.3k followers
And the script keeps scrolling till the end by clicking on start autoscroll.

it does not work in chrome :(

That's not a lot of information to go on. Please post some error messages.

First of all Developer, this is a great script, beautifully written, works wonderfully on Firefox.
Now I wanted you to add on to this script.
by considering this script
