Revision 8b1b667e-2dd3-424a-9c71-add76b8c5d8f

I am having this very strange pop-up ads issue when accessing any Stack Exchange site using Firefox. Whenever I click I get redirected to ads. I have done and tries the following:

   - cleared cookies, history, cache, etc.
   - disabled Firefox sync

but nothing works. I accessed Ask Ubuntu from Chrome and I didn't have that issue there. Now I did this based on this [post][1]:

1. opened page source code for Ask Ubuntu, and I saw this:

        <body class="home-page new-topbar">
        <noscript><div id="noscript-padding"></div></noscript>
        <script>(function () { var old = $.fn.contents; $.fn.contents = function () { try { return old.apply(this, arguments); } catch (e) { return $([]); } } })()</script>
        <iframe id="adzerk-user-match" width="0" height="0" frameborder="0" scrolling="no" onload="window.AUMIframeDone=true"
            src="https://ssum-sec.casalemedia.com/usermatch?s=183712&amp;cb=https%3A%2F%2Fengine.adzerk.net%2Fudb%2F22%2Fsync%2Fi.gif%3FpartnerId%3D1%26userId%3D"
            style="display: none;" marginheight="0" marginwidth="0"></iframe>

2. But on Chrome, I see this with the same method as in 1:

        <body class="questions-page new-topbar">
        <noscript><div id="noscript-padding"></div></noscript>   


3. Opened Ask Ubuntu in Firefox inspect tool and I saw this, just like in chrome:

        <body class="questions-page new-topbar">
        <noscript><div id="noscript-padding"></div></noscript> 

Now I don't know where that piece of injected code is coming from but its only seen when using Firefox. My problem here is that I get this issue only when on Stack Exchange sites.

How can I tackle this?

Now on the request i have added three _images_ for __ads that just popped up as I tried signing in to askubuntu from firefox with my adblocker app turned off__ just less than 2mins ago.
