  1. Nice plug-in. I installed the code in my footer so it is on every page and it works when I click once the only problem is that it pops another window on every page I visit.

  2. Hi there,

    The popunder works great in Firefox but for some reason in Internet Explorer, the new window doesn’t load underneath the current page. It loads on top of it. Can this be changed?

  3. Hello, the pop up is not working. I just want the very basic pop. I followed the directions in the video but nothing happens. Was I suppose to install code somewhere?

  4. How do you manage the “browser session” ? I would like to open the popup only one time per visit. And i think i´m only seeing it once per day or something like that… 😉

  5. whem I use my ipad with Safari or Google chrome the popunder is instead of it a popforward! The page which I want to be a popunder, is now a new page that opens than.
    The page which is under the menu I clicked is not on the screen but one page back!
    On a pc all is going well!
    Can you give a solution for this?

  6. Hi,

    we have your plugin in use. It works on other sites we are using very well, but on one site we have the problem, that the popup is still blocked. Do you have a solution for this ? We are using the current version 1.3


  7. Hi.. thanks for the plugin. Did u think it safe for adsense or related ptc program ? Just need some advice. Because, i wanna put adsense code on pop up page.

    Thanks in advance..

  8. Actually I think this plugin is good, if only the popup size can be resized. I wonder can it be really under the window? So that people don’t realize that they open a new window behind it?
