Look at where the interruption appears
A new browser tab or window is different from an alert shown by the operating system. Microsoft explicitly distinguishes website notifications from pop-ups. A page can use both, so blocking one type does not establish that every later message comes through the same mechanism.
Notifications can outlive the visible window
Microsoft notes that allowed Edge website notifications can appear even when Edge is closed. Closing the player tab is therefore not equivalent to removing a notification subscription. Review the actual site permission if alerts continue after the viewing page is gone.
Pop-up controls govern another action
Google documents a blocked-pop-up indicator and separate lasting website exceptions for pop-ups and redirects. A legitimate action can open a separate window, but the destination should still be checked. The decision to inspect one intended window is different from allowing future pop-ups from that origin.
Avoid following an alarming alert
An alert’s wording is not a reliable reason to enter payment details or install a repair tool. Identify its source through the browser’s saved permission controls where possible. If the domain is unfamiliar, you can revoke its notification permission without revisiting the page just to interact with the message.
Describe the evidence clearly
Tell support whether the item appeared as a new tab, a separate window, an in-page banner or a system notification, and include the public source domain if visible. That classification helps select the correct control. It does not prove every unexpected message is malware or that clearing all browser data is necessary.
Questions, answered
Will blocking pop-ups necessarily stop website notifications?
No. They use different controls.
Does closing Edge revoke notification permission?
No. Microsoft says permitted site notifications can still appear.
