What is an Ad Blocker?

Ad blockers are applications (plugins or browser extensions) that remove or alter advertising content on a webpage. While a webpage is loading, the ad blocker looks at the site's scripts and compares them against a list of sites and scripts it was built to block. If it finds any, it blocks them.

How to see if you have an Ad Blocker installed?

The most definitive way is to look for an ad blocker is to check to see if they are in the list of extensions installed in your browser:

In Chrome or Opera, type about:extensions in the address bar
In Safari, go to Safari > Preferences > Extensions
In Edge, click More (...) > Extensions
In Firefox, open the Firefox menu, select Add-ons, and then click Extensions in the sidebar

How to Turn off the ad blocker [In Chrome]

If you trust a site, you can add an exception to allow ads on that site.

Open Google Chrome.
Open the Settings menu, and click Security and Privacy.
Select Site Settings, and then click Additional permissions.
From here, you can toggle Ads on or off, and also adjust Popups and redirects.
You can Add datazone.org to the list of allowed popups and redirects.
