Ad Radar από Hestia.AI

Ad Radar is an extension that allows you to understand how much is being paid for your attention online, by displaying price information next to the ads that you see.

Note that this extension is still in an early version and is being improved.

Ad Radar only works on some web pages that use a specific ad-serving mechanism known as Header Bidding.
