That cant be this extension. Check the other extensions that you have.
Also search for the image ID on various boorus if you are trying to find something.
I swear your extension used to show IDs under deleted or private works. Pixiv must've fucked something up because it doesn't do that anymore, and using sauceNAO just tells me the image no longer exists on the remote server, meaning they're lost forever since they were from 2019 at best...
