Let us continue this discussion in chat.

Can you please instead check your browser's console. Which browser btw? Can you take a screenshot of the message if possible?

OK :) I can't think of a reason for the button not showing up... It works for me...

OK, looks like you're looking in the right place. Does anything show up in the console?

It's weird that you can't see the 'self-destruct access-token' link - are you sure you're looking in the right place? On your profile, at the top... And I've edited the URL so clicking Comment self-destruct shouldn't lead to stackapps.com anymore

Are you still looking for this? I'd be happy to try and make one :)

@BrockAdams I've edited the script to require jQuery. I've tested it and it works now in Firefox :)

@Buscar웃 I need to do something about this..! Nobody knows how to!! Not your fault - it's a bit complicated; I'll see if I can make it easier. But for now, clicking get it here on that mini-site should take you to an authorization page, clicking approve should take you to SE's homepage - the URL will be a bit different. Then you can just do what I said to do in this comment :)
