The list of blocked add-ons at https://blocked.cdn.mozilla.net/ is useless, as it doesn’t actually list which add-on is blocked.
Also, if you do look at an entry on that list it has a link to “View block request”, but any attempt to look at the target of the link (I’ve tried quite a few) produces the message:
Access Denied
You are not authorized to access bug nnnnnnn.
