Greasy Fork

Doesn't work on Amazon, any longer. Here's the fix.

The problem is that the ID it is looking for is not on Amazon any more: "#tell-a-friend"

I changed the last line to prepend to "#addToCart" as that seems like something Amazon is not likely to remove:
document.querySelector("#addToCart").appendChild(link);

Now it works again.

Hey, thanks for the feedback. I haven't been uploading updates to greasy fork anymore. You can find a more up to date version at https://openuserjs.org/scripts/Littlefinix/Amazon_URL_Shortener
