In 2014, Michael Gundlach (the creator of the AdBlock extension) discontinued his pay-monthly "CatBlock" extension, that let users replace ads online with cats (or any other image from Flickr).
As he open-sourced the code, a few contributors to the project decided to fork the code and continue maintenance of the extension.
We have since gone on to improve the ad replacement code, and make sure it's working well for all users.
