Fetch the URLs of a Facebook sticker pack! Also the very first gist of mine featuring ES6.
// Before using,
// 1) add an ID (`ggg` in this case) to the container of the table of the sticker pack you want.
// 2) The static ones are cached unless the animated ones are needed so you must move your cursor through all the stickers.
// Hint: The URLs can be fed into DownloadThemAll! or something else.
Array.from(document.querySelectorAll("#ggg ._5r8i"))
.map( x=>x.style.backgroundImage
.match(/https[^"]+/)[0]
.replace(/(s|p)\d+x\d+/, "") )
.join("\n")
