Does not work for me. Guessing from the top of my head, this is because my Steam profile is not public. Which would be understandable, but I still would like to see a list of limitations in the description.
Also, most Steam users have no idea what SteamID 64 is and how to retrieve it. On top of that, the extension description does not mention that the said ID have to be retrieved and added to extension options manually.
