Doesnt Work in Firefox for Mac

good but heavy

Quand je l'ai essayé pour prendre la couleur d'une image, il a juste fait ramer Firefox pendant un moment en refusant de sélectionner la couleur. C'est dommage, mais l’extension ne sert du coup à rien.

It doesn't appear to work at all.

I select the eye dropper and firefox tells me "ColorZilla is causing firefox to slow down"

После того как определили цвет, скопировать его не возможно, приложение сворачивается и исчезает.... Очень не удобное.

Hi, By some reason it's not working, I run this in chrome without any problem but here the colorpicker never starts... Any clue?

Addon quit working after Firefox update. Loved this addon because I'm a web developer, and happen to be colorblind. Sadly I can't rely on this tool anymore to assist in my work... will find a new one.

Crashes regularly in addition to slowing down the browser.

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.

its not work

Most of the time it returns a wrong color. Useless in a production environment.

Manipuliert die Startseite. Nur schwierig wieder zu entfernen. Vorsicht! Kein seriöser Anbieter.

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

Not working correctly.

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 :-)

Troy Cptn Mrld man. Clros fo hte skmo.

Doesn't works on latest firefox versions

I'm not at all sure what this does or how to use it. Anybody know?

doesnt work at all. I have tried everything but couldnt pick any color anywhere. Its shit!

I used to love this tool and I used it since it existed. Since the so called upgrade with this bunch of useless tools it became complicated. It's overloaded with too much tools I seriously never needed! All I need is a simple color picker which can add either the hex or the RGB value of my choice to clipboard everything else is overrated and not needed... but oh well I guess I have to use it since this is the only alternative which works with the current Quantum Version. I wish it would be more simple... or at least an alternative version of Colorzilla which only contains the colorpicker itself without such extravaganza...
