Question: I'm embedding page that has an exit pop-up. When you close the page, it automatically launches a pop-up window.

**How to disable pop-ups coming from the iframe on exit?**

Answer: 
Quite an old ask, but I thought I'd offer a newer solution since this is the top result in google.

If you want to block an iframe from opening windows, you can use the new HTML5 "sandbox" attribute on your iframe.

<https://developer.mozilla.org/en/docs/Web/HTML/Element/iframe>

This should keep it from doing anything (except running javascript which may be required for the page to function correctly):

```
<iframe sandbox="allow-scripts" src="your/url/here"></iframe>

```
I'm not sure if this would work but you could try double Iframing. Iframe the site in a free blogger account, then iframe the blogger account with a delay loading code. so the popup will occur before the page is loaded let me know if it works.
