I visited a YouTube proxy website, NSFWYouTube, and since then I receive unwanted push notifications from that site like this:

There doesn't appear to be a way to disable it in Firefox Mobile 65.0.1 -- the Mozilla's Support site says to go to the site, click the "lock" icon and disable notifications there. But there is no notification option when I try; the site is not an HTTPS site (not sure if that's why).
I do not recall accepting notifications, is it possible the site click-jacked me into doing so? How can I disable these notifications?
