I constantly encounter websites unsupported by the add-on, and it seems like the the report button doesn't work for me. I've reported several websites (more than a dozen) by selecting "Report Problem", "I still have cookie pop-ups", and I click send. But when I look in my super-agent options, it says "You haven't reported any websites yet."

Let me know if I'm actually doing something wrong, and I'll happily adjust this review and rating.

EDIT: I've corresponded a bit with the developer about this issue. They were very nice. It seems like my reports are most likely being received, even though I can't see them. And they've added support for all the sites that I've reported. I still can't see my reports, but I guess I can just submit them by email. I might give 4.5 stars if I could, but I think it's more fair to round up than down here.
