About CUBEFISH

This is an extension that allows you to customize your background on arbitrary websites. You can choose backgrounds from a number of presets, full color backgrounds or you can add your very own image as background using an image URL. Backgrounds can be applied to single pages, full websites or even to pages that match a certain URL pattern on a specific domain! Currently it changes the background of the html `body` element of the website. Therefore, it might not work on all websites, namely where the `body` is not visible.
