# How to Use the Popup Builder Adblock Extension

The **Popup Builder AdBlock extension** warns the website visitors that there is an adblocking extension on the current browser blocking the popups. It is a useful tool, with which you won't miss any available promo/sales popups on different websites.

|| The extension is paid and can be purchased [separately](https://popup-builder.com/product/ad-block/) or within a [bundle](https://popup-builder.com/pricing/).
Once you are done with the purchase, make sure to install it like this:

* See the installation process as a single extension in this [article](https://help.popup-builder.com/en/article/how-to-install-a-single-extension-1gc5noh/).
* See the installation process within a bundle in this [article](https://help.popup-builder.com/en/article/how-to-install-bundle-paid-version-3364s5/).

| Make sure to have at least one popup of any type created to use the AdBlock event.

### Required Steps to create an AdBlock Popup:

1. Go to the **Popup Events** section and select **Adblock** from the dropdown menu.

2. From the **Delay** section you can set popup's delay time

| Please note that with no delay time, the Adblock popup will be triggered as soon as the page is loaded and ad-blocking software is detected.
