We are aware DrDos, we've received quite a few comments along the same line.

I have tested it in Edge, Firefox, Chrome, and Brave and am unable to replicate the issue. With those browsers at default settings, and with zero active extensions, the popup does NOT appear. I have tested three times now, each time with the same result.

There has to be something on your system still blocking the ads. Possibilities include:

1) An active extension - are you ware that anti-tracking extensions also block ads?
2) Some 3rd-party security or privacy software is running. We had one similar case where a user was still seeing the popup and it turned out to be a setting in his Kaspersky antivirus
3) Using a DNS provider which includes an ad blocking feature
4) Using a VPN which includes an ad blocking feature
5) A setting in the router
