It does all needed: picks colour from the browser :)

FAVORITE extension. Had this on Chrome and use it still now I'm on Firefox. Use it a LOT, especially when I'm working on doing CSS/HTML for websites and I want to color-match things and need the hex code :) Only thing is when the bar drops down, it throws off the picker so you're picking colors that your cursor isn't hovering over.

C'est exactement le plugin que je recherchais. Très complet et totalement fonctionnel sur firefox 103.0.2
