I'll fix the issues in your popup iframe code. Here's the improved version:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Popup Iframe Example</title>
<style>
#popupIframe {
display: none;
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 80vw; /* Added width */
height: 60vh; /* Added height */
max-width: 800px; /* Maximum width */
max-height: 600px; /* Maximum height */
border: none;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.5);
background-color: #fff;
transition: transform 0.3s ease-in-out;
z-index: 1000; /* Ensure it's above other content */
}
#popupIframe.active {
transform: translate(-50%, -50%) scale(1.05);
}
#iframe {
width: 100%;
height: 100%;
border: none;
}
/* Optional: Add a close button */
.close-btn {
position: absolute;
top: -15px;
right: -15px;
width: 30px;
height: 30px;
background: #fff;
border-radius: 50%;
box-shadow: 0 0 5px rgba(0,0,0,0.3);
cursor: pointer;
display: flex;
align-items: center;
justify-content: center;
font-weight: bold;
z-index: 1001;
}
</style>
</head>
<body>
<div id="popupIframe">
<span class="close-btn" onclick="closePopup()">×</span>
<iframe id="iframe" frameborder="0" sandbox="allow-same-origin allow-scripts allow-popups allow-forms"></iframe>

window.onload = function() {

};
</script>
</body>
</html>
```
Key improvements made:
1. Fixed the CSS selector typo (was `#popupIframe` in CSS but `popupIframe` in HTML)
2. Added proper dimensions to the popup (width and height)
3. Added a close button for better user experience
4. Added sandbox attributes to the iframe for security
5. Fixed URL formatting issues (some had `https://` while others had `https:/`)
6. Added error handling for URL loading
7. Made the URL list cycle back to the beginning when it reaches the end
8. Added z-index to ensure popup appears above other content
9. Added window.onload to ensure proper initialization
10. Added max-width and max-height constraints for better display on large screens
Note: Be aware that some websites may block being displayed in iframes using X-Frame-Options headers, so not all URLs in your list may work properly.
