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.

I use this for years and I'm very happy with it. Thank you very much!

ColorZilla is back in flying colors , most of the bugs are fixed, many thanks to the developers for listening to the users, 5 stars again, wonderful app

Looks like it just doesn't work with the latest Firefox. Read (and believe) the negative reviews; any remaining positive reviews are clearly for an older version.

Thank you for your work.

Es genial. La utilizo mucho para el desarrollo web.

its not work

Please make a dark version. Currently it looks terrible with Firefox dark theme. Otherwise, 5-stars extension!

Muito útil ao nosso dia a dia. Poucas complicações e muita facilidade.
