Stopped working Rated 1 out of 5 stars

As others have said, the whole page is evaluated as white now. And since the eye dropper from the Developer Tools was removed there is no alternative either.

As of yesterday, in Ubuntu 16.10 x64 with Firefox 51.0.1, this version does not work. The entire page is evaluated as white (255,255,255).
Last week was working fine.
I'll rate again if starts working.

Doesn't work with e10s (separate process) Firefox Rated 1 out of 5 stars

In the past I would have given this a 5-star review, but over a year after e10s was out in nightly and Developer Edition, and now that it's rolling out in Release, Colorzilla still not updated. Your extension can't access anything on the page being rendered, because it's in a different process. Other developers have fixed their extensions to work with e10s. Further, your Chrome version of the extension, when loaded into FF via "Chrome Store Foxified" using Firefox's new extension API, does not work.

Once-great extension, now 99% worthless, that is not using any of the modern Firefox APIs and no action from the developer.

The 1% not worthless? If you open a "New non-e10s" window from the Firefox menu, then re-browse to the page you want to color-pick from, Colorzilla will still work in that.

Doesn't work Rated 1 out of 5 stars

Lot's of features but the essential one didn't work. I can't pick a color from the page, only from the browser chrome... The add-on says the whole page is white, so I assume this is a bug. Tested in Ubuntu, firefox dev edition.

Colorzilla - bringing the colors of the web to you! Rated 5 out of 5 stars

After installing and using ColorZilla for a little bit, this add-on proves to be quite handy for all things COLOR on the web. From selecting/matching colors from a certain website to generating custom gradients, ColorZilla does a lot!

Pros: I was quite impressed with the DOM Color Analysis that will pull the colors from a website and create a palette that you can then refer to and use.
A drop-down appears when using the eyedropper and it is both full of useful information and non intrusive.

Cons: The only really big con that stuck out at me was when I went to open the Color Picker, the window was not sized properly :( I am not sure the zoom functionality is really a necessary part of this add-on as zoom functionality is built into Firefox.

It is quite obvious the amount of work that has gone into this project.

The one thing I was going to say would be a nice addition would be the ability to set a keyboard shortcut for the eyedropper, but hey look at that, it is there underneath the options drop-down!

Overall runs smoothly and has become a very neat addition to my set of Firefox tools!

Rated 4 out of 5 stars

Although the extension says it's signed, I'm seeing this alert in the FF list: "ColorZilla could not be verified for use in Firefox." I think that means it will break soon... are other users seeing this in their Add-Ons page (extensions list)?

Stunning Rated 5 out of 5 stars

A truly stunning extension in every sense. View colours using every method (hex, rgb) and even set the copy-to-clipboard as lowercase. Incredible.
