PopupBlocker is a powerful pop-up blocker.

It automatically closes all kinds of popups: the ones created by certain websites, the ones you don't want to see (like an ad), the ones your computer/browser automatically create, etc.

You can add sites manually, but that's just extra work.

It's all handled automatically, and works for every website and browser.

This extension is completely free to use.

How to use PopupBlocker

After installing the extension, open a website and click on one of the advertisements (randomly). Then click on the extension and a popup will appear. To disable ads, click on the extension again.
