That's what I use, and I never see popups on any website,

https://adguard.com/en/adguard-browser-extension/overview.html

if something is glitching out try this:

Dell laptop, Windows 10, Build 21H2, Edge browser right now. I can't change the browser settings.

To be clear, what you're seeing obviously isn't supposed to be happening. We use a third-party service to handle push notifications and since I've seen a couple of people with this issue, it looks like something might have gotten mixed up with the integration after the DU4 launch. I've contacted their support to see what's up.

In the meantime you might find this useful if you have not seen it already. It describes how to block individual websites from sending you notification requests. The section you want would be "How to turn off notifications for specific websites":

I’m posting from my phone now, but the laptop I post from is someone else’s. The owner gets to chose the browser settings

Thanks again, and good afternoon.

Thanks for your help!
