Where do notifications to "usefulcontentsite.com" come from?

Sometimes I get notifications from Firefox which send me to "usefulcontentsite.com" (don't click this, might be harmful!) and when I click them, uBlock Origin blocks them. So I'm pretty certain that is spam (or worse). However, I could never attribute this to any page or maybe some harmful extension I have installed. Also, I mostly block site's requests for notifications.

Here is the list of installed add-ons: - ClearURLs (recommended by Mozilla) - Firefox Multi-Account Containers (official extension) - KeePassXC-Browser - uBlock Origin (recommended by Mozilla) - User-Agent Switcher and Manager (recommended by Mozilla)

So imo nothing exotic here.

Does anyone here have a clue where those notifications might come from?

Have you checked your push notification permissions?

Good point. I allow notifications only for two Mastodon instances. And it would be weird if they sent me to an unrelated domain... Are there any logs about which pages sent notifications?

The notification should indicate the site responsible.

It doesn't for me (I'm on Ubuntu with KDE, not sure if that matters). I just tried it, here is how a test notification looks like.

Visit about:serviceworkers in the address bar and check for registered push endpoints.
