Hi, By some reason it's not working, I run this in chrome without any problem but here the colorpicker never starts... Any clue?

Very nice, well thought, easy to use.
That was the one I was searching for, and it is even better than I thought
Thanks a lot Alex Sirota for this gem.

Addon quit working after Firefox update. Loved this addon because I'm a web developer, and happen to be colorblind. Sadly I can't rely on this tool anymore to assist in my work... will find a new one.

Crashes regularly in addition to slowing down the browser.

Great for picking colours from any site.

Firefox has a dropper tool. It worked for me until I realized it, but now I'm removing it. I didn't like that the license was custom anyway.
