How to block pop-ups from a particular site
Chrome blocks a majority of pop-ups very well, but sometimes it pops up – or you accidentally click "Allow" instead of " Block "- and get to your screen. To explicitly block a site from showing pop-ups, you can add it to Chrome's block list.
Click the menu icon, then click Settings. Alternatively, enter:

. On the Settings tab, scroll down and click Advanced. 
Scroll down to the "Privacy and Security" heading and you'll see the "Content Settings" option. Click on it.
In the list of settings, click the "Popups and Redirects" option.
If you've accidentally added a site to the Allow List, you can immediately revoke its permissions so Chrome will block the popups again. Otherwise, you must manually add the problem URL to the revocation list. We will guide you through both cases below.
Under the "Allow" heading, locate the problem site, click "More" (three dots) and then "Block".
