How to enable or disable popup window in google chrome?

When Google Chrome blocks pop-ups, you might not even notice it. If you look minutely,  a small blue and white icon with a red cross (“X”) on it appears in the extreme right hand side of the address bar.

Just click on this icon, you can see a list of the pop-ups blocked for that page. You can click on the items in this list to view them, and you can also select the box to “Always allow pop-ups” from the site you’re on (refresh for this change to take effect).

To manage the sites on this pop-up “whitelist,” or to disable the pop-up blocker entirely, follow the path;

Tools > Options > Under the Hood > Content settings… > Pop-ups.
