Google Chrome's pop-up blocker is on by default. To change the Chrome's pop-up blocker settings you will need to follow the steps below:
1.) Click on the icon pictured below (it is in the upper right hand corner of the screen) and then click Settings at the bottom of the menu that appears.
2.) At the bottom of the screen you will see a link that says "Show advanced settings...", click on this.
3.) Scroll down until you see the Privacy header. Click on the Content Settings button directly beneath the word Privacy.
4.) Scroll down until you see the Pop-ups header. If you would like to allow all pop-ups from all websites (NOT recommended) you can change that option here. If you instead would like to allow a single website to display pop-ups, click on the "Manage exceptions" button.
5.) In this menu you can allow or block certain websites from displaying pop-ups. Simply copy and paste the URL of the website into the box labeled "Hostname pattern" and change behavior to either Allow or Block and press Enter.
