Fails to work on any of the web pages I actually need it for. Using this on a Wikipedia image or Google Images shoots the CPU utilization up to 100% causes a pop-up that asks if I want to disable the extension on this page.

Used to be a good extension, now it's garbage.

Makes Firefox to consume 100% CPU when activating color picker (Firefox 61 , Linux Mint 18.2). Freezes the whole system for several minutes. Q_Q

Have always enjoyed using this - although better when it was simpler and didn't move the page around.
Just the eyedropper and an info bar.

Not working correctly.

Excellent add-on. Highly recommended.

I removed from my screen by mistake, how I get it again in my laptop screen?

très bien

Very slow, lots of bug.
Sometimes break page completely.

The picker didn't work well for me:
- No real-time color feedback
- No disabling of page links while picking colors... (annoying)
- Didn't actually pick anything unless it was inside the color selector... which isn't actually color picking as far as I can tell.
- The color analyzer was slow for me on a i7 7700K @5Ghz + 16 GB of RAM
- There's a working color picker already in the browser by pressing F12 (DevTools)

Super!

Cannot sample colors from images. Feels somewhat bloated with features, and occasionally causes browser to load pages slowly.

Still better than most other color-picker add-ons I've tried. Works on animated elements too.

Tried a bunch of others. This is the only one that works for me on the Mac. Very nicely done.

All it does is cause the page to freeze ... "script slowing down FF." It used to work great and now it sucks. It's this way on 2 different computers, both running FF 60.0

Great add-on! I've been searching for a long time plugin similar to ColorPicker Eyedropper from Opera.
