+++ This bug was initially created as a clone of Bug #1401614 +++ User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0 Build ID: 20170918210324 Steps to reproduce: Hello and thank you by advance for looking into this bug! On Windows 10 - Firefox version 56.0 beta (same bug on stable version 55) - In Firefox, right click anywhere and "Inspect element" - On the CSS part, click on any color circle to open the color picker (any CSS property that has a HEX or RGB code) - Use the eyedrop tool and select any color. - Open the color picker again. - Click anywhere inside the color picker to change the color. - Click again in some place else to change the color another time. Actual results: After using the eyedrop tool, if I want to change the color and open the color picker, the first change of color works properly. The second one (and all the further changes) : -is not applied on the selected element on the page. -the HEX or RGB code on the inspector's CSS doesn't change. I have to close the color picker to be able to try another color. The problem applies to all colors on the page and stays untill I reboot Firefox. Expected results: I used to be able to pick a color with the eyedrop tool and then change it as many times as I wanted using the color picker. - the changes I make should show on the page. - the HEX or RGB code should change in the CSS.

Thank you for filing Agnes. I think this is a duplicate of bug 1365053 which was fixed in Firefox 57.

Thank you for your reply and sorry about the duplicate! Gives me some more reasons to use Nightly :)
