Eccelent! Merci!

This was misleading

I was looking for an extension that would allow me to pick colors from a webpage. This does not do that. It allows users to create color palettes. It seems to work fine for its intended purpose, but I'm not really sure why you would need to do this in Firefox directly. I would instead use my editing software directly, and this same functionality is duplicated in any editing software I use (Photoshop, Canva, G-Suite, etc.)

NOT A COLOUR PICKER!

It simply didn't do anything. Will uninstalled.

Not a color picker

doesn't have any tool to pick colors from web pages, so it's basically useless

does not have dropper option

I needed a color picker which had the little eye-dropper tool. While I did not find the eye-dropper I liked what it appeared to do and so began reading the instructions. However the location of the "4 sections" and the "3 buttons" mentioned in the first paragraph did not match what appeared on my screen. I spent a little more time on learning the extension, but regretfully have to move on, so I removed it but hope to return in the near future.

Doesn't pick colours from page

Very useful and practical
