When I open Web Developer Tools -> Inspector -> Eyedropper the eyedropper just shows a circle but does not copy or display the colors as you hover over them. When you click it just copies #000000 to the clipboard.

The only way I can use the Eyedropper is by going to: Tools -> Browser Tools -> Eyedropper.

My current Firefox version is 94.0.2 and I noticed this issue within the last minor/major update. I also noticed that the issue heavily depends on the website you are trying to get colors from. Some websites work fine while others it does not work.

When I try it on Hacker News (https://news.ycombinator.com/) it does not work for me.

That is a bug in Firefox with the developer tools and CSP related issues. It works if I disable CSP.
