Delete all your favorites (unfavorite or unlike every tweet) on twitter.com (thx to @JamieMason and @b44rd for inspiring this)

unfavorite.js

// 1. Go to https://twitter.com/i/likes
// 2. Keep scrolling to the bottom repeatedly until all your favs are loaded.
// 3. Run this in your console (open in chrome by View > Developer > JavaScript Console)
// Notes: this may take a while if you have a lot of favs/likes
//       you can only access your most recent ~2000 likes.

setInterval(() => {

}
window.scrollTo(0, document.body.scrollHeight)
}, 1000)
