yep same thing here on firefox, every group has "no info" as the website

Seeing as Chrome won't list the extension on the store anymore, would it be possible to zip up the file so we can add it as an unpacked extension manually ourselves, like other "unofficial" Chrome extensions eg. GrooveShark Downloader?
Their tutorial video on how to add extensions is super easy to do that even I was able to install their extension! xD

@people having it no longer work in firefox:
You probably have noscript or something else that blocks javascript installed.
Since some version of the script, you need to allow javascript from "loadletter.github.io" to have the links to the groups appear.

Thank you connerity! That did the trick ^^

This is an updated version suitable for various browsers.
