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.

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

Good

supp.

Seems not be working at all in Firefox 59. A shame, as this has been one of my favourite add-ons of recent years. Hope you can find time to look at it :-)

FABULOUS is the only way to describe ColoZilla. Have been using it for almost a decade and derived immeasurable benefit from it.

Works but the Tabs Color are very Ugly. In the Old Firefox iot looks better.
