Great add-on! I've been searching for a long time plugin similar to ColorPicker Eyedropper from Opera.

Good

Seems not be working at all in Firefox 59. A shame, as this has been one of my favourite add-ons of recent years. Hope you can find time to look at it :-)

FABULOUS is the only way to describe ColoZilla. Have been using it for almost a decade and derived immeasurable benefit from it.

Works but the Tabs Color are very Ugly. In the Old Firefox iot looks better.

It works very well, but the only problem is that SpyHunter said it is has a malware inside. Would you please check it? Tried 3 times with fresh install but the result is the same

Works perfect, and have many options to pick the color in different manners and get the color in different formats.

I had read some reviews saying that this plug in had stopped working, but even a brief test showed that the core functionality is exactly as expect and very useful . Five stars, many thanks :-)

Wonderful.
