Hi @rcaz
Does the issue happen with other websites? If so, are the pop-ups the same in different websites? You could also provide a screenshot of the issue.
I'm not sure if that's malicious sites pop-ups, you can try to turn on Microsoft Defender SmartScreen on this page edge://settings/privacy, and turn on Blocked (recommended) on this page edge://settings/content/popups to see if it can fix the issue.
