Description from store

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.

Blair Thoennes 2019-06-23: Way easier than holding a cat against your screen. Also I like that you can X out of the images to get more space on the webpage, it's really good.

L 2018-06-03: On my ubuntu box it suddenly blocked a non marked site and insisted I needed to upgrade to see my very normal webpage. This has therefore been uninstalled from that machine.
