What Is Causing Some Sites Are Embedded Within An Iframe in Google Chrome?

Some sites are served within an iframe (only) on Chrome.

Here's an example of the source code of Digg.com served within an Iframe:

<html class="gr__digg_com">
<head>
    <noscript>
        <meta http-equiv="refresh" content="0;URL=http://digg.com/"/>
    </noscript>
    <script type="text/javascript" src="http://ibnads.xl.co.id/ads-request?t=4&amp;j=2&amp;callback=iframe.jsonp454&amp;rnd=452&amp;a=http%3A%2F%2Fdigg.com%2F&amp;i=176791713"></script>
</head>
<body data-gr-c-s-loaded="true">
    <div id="container">
        <div id="top-banner"></div>
        <div id="middle">
            <div id="left-banner"></div>
            <div id="content">
                <iframe id="main-frame" frameborder="0" style="width: 1333px; border: 0px; height: 8200px;" src="http://digg.com/"></iframe>
            </div>
            <div id="right-banner"></div>
        </div>
        <div id="bottom-banner"></div>
    </div>      
    <script type="text/javascript">p={'t':'4', 'i':'176791713'};</script>
    <script src="http://ibnads.xl.co.id:8004/COMMON/js/if_low_20150915.min.js"></script>
</body>
<iframe allowtransparency="true" frameborder="0" id="abs-top-frame" src="chrome-extension://flliilndjeohchalpbbcdekjklbdgfkk/html/top.html?1457289833178#minimized" style="position: fixed !important; z-index: 2147483647 !important;overflow: hidden !important; top: 0px !important; left: 0px !important; right: 0px !important; width: 0px !important; height: 0px !important; max-height: none !important; min-height: 0px !important; margin: 0px auto !important; padding: 0px !important; border: 0px !important; display: none !important; background-color: transparent !important;"></iframe>
<span class="gr__tooltip"><span class="gr__tooltip-content"></span><i class="gr__tooltip-logo"></i><span class="gr__triangle"></span></span>
</html>

The actual Digg.com content is embedded within<iframe id="main-frame">.

This causes an ugly extra vertical scroll bar.

The URL in the address bar is still digg.com.

I tried to visit the sites (digg.com and some other sites) in Firefox, and they look fine.

I suspect that it's caused by a browser extension, but I don't know what it is.

Here are all browser extensions I have installed on Chrome:

  • Alexa Traffic Rank
  • Avira Browse Safety
  • Google Docs
  • Google Docs Offline
  • Google Mail Checker
  • Google Sheets
  • Google Slides
  • Grammarly
  • Instapaper
  • Wikiwand

Does anyone know why some sites are being served within an Iframe on Chrome?

You can uncover the culprit by looking at the source of the offending iframe: src="chrome-extension://flliilndjeohchalpbbcdekjklbdgfkk/html/top.html?1457289833178#minimized”

In chrome://extensions, you can turn on the developer mode, and this will show the id of each extension. Then you can search through for this id flliilndjeohchalpbbcdekjklbdgfkk, but this turns out not to be necessary.

The chrome store organizes things by their id, so you can go to https://chrome.google.com/webstore/detail/flliilndjeohchalpbbcdekjklbdgfkk and find out that it’s Avira Browser Safety.

I had this iframe as well. The Avira Browser Safety extension is causing it.

Uninstall it and the iframe on top of the window is gone.
