WARNING: THIS USER SCRIPT NO LONGER WORKS - IT WAS ORIGINALLY MADE FOR THE TWITTER WEBAPP PRE JULY 2019

Download either Tampermonkey for Chrome, or Greasemonkey for Firefox if you want to run this script repeatably:

Tampermonkey: https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo

Greasemonkey: https://addons.mozilla.org/nl/firefox/addon/greasemonkey/

Add the script via the dashboard of Tamper/Greasemonkey, and then simply navigate to https://twitter.com/i/likes to download your own likes, or replace 'i' with any other username to download their likes.

You may alternatively run this script in your console. You can open this in most browsers by pressing F12 on your keyboard, or right clicking anywhere on the page and selecting 'Inspect Element'. Simply paste the script there and press Enter to run it. The easiest way to copy the script is by pressing 'Raw' below on userscript.js and copying all the text.
