To the developer: The icon for this addon is next to invisible on my top right where it is located. Its color is a faint grey. In order to have it visible you need to put it in white instead. Thanks to consider solving this icon issue.
The background color of the icon was transparent, which made it hard to distinguish the contours on Firefox' grey user interface. As of version 0.1.2, the icon's background is white, thanks for the suggestion!
