Sorry, I was forced to install the last good version (2.8.2) and disable updates:
https://addons.mozilla.org/En-us/firefox/addon/colorzilla/versions/?page=1#version-2.8.2

Used to use this every day. Now it's a pile of rubbish. Doesn't record the colour I click on more than 2/3 of the time, records the wrong colour, laggy and slow to respond. Menu options were changed so can no longer copy RGB from first dropdown.... and Copy RGB from the new secondary menu just flat out doesn't work.

What an embarrassment!

Now I'm using Color Picker and recommend everyone to switch to that, it's light, accurate and does exactly what it needs to.

This was a very good extension, with the new update it's the worst eyedropper.

Don't know how to revert, but I do know how to uninstall. This add-on is now like a boat that refuses to float.

I had to revert back to version 2.8.2 and turn off auto updates, v3 I found totally unusable, please revert back to the earlier interface, I promise I'll donate!

Much slower then the previous version, color picking from local images do not work anymore..
It says "Click to Allow access to file URLs" but nothing happens on click... The black bar that appears after u get the color picker is not fixed - it offests the web page for the height of the bar.... It used to be one click picker, now there's a n extra click... All in all, i think I'm rolling back to previous version - the new one doesnt live up to it's name....

Used to be great.

Todo funcionaba bien hasta que decidieron actualizarla, ya no funciona para archivos locales y se supone es una herramienta para diseñadores.

eliminada por se obsoleta, no la instalen !

bad

Oh no! I often want the rgb value (because I use rgba) and it's gone. PLEASE put it back the way it was

I have been using this tool for years and I even recommended with my users and clients. Now I will start the process of doing the contrary. The new update and interface change made this tool bad, really BAD...

As a webdeveloper I'm using this tool for years, but now it has changed so much, I can't use it anymore! The greatest mistake developers can make is to CHANGE it so much that the user needs to study it again. And we don't!
Pls bring back the standard functionality, and REMOVE the pop up bar in the top! Whether or not I disable it, it keeps showing!

They have changed everything!
It has become very complicated !!!!
Too bad
I will therefore uninstall

This was the best add-on for Firefox out there, now it's useless and doesn't work... :-(

I relied heavily on the zoom-in/zoom-out feature which I easily located by right-clicking. It's no longer there nor all the options that came with it. I'm going to have to remove colorzilla (again, have already removed, reinstalled, restarted browser, hoping it would restore the program). I'll have to go shopping for alternative programs but I'll check in time to time and see if this once awesome program has been restored to its former glory.

The new functionality of this has ruined this addon. I used to be able to grab the color and then choose which format I needed on the fly with a drop list. Now I have to set the format (hex, rgb, etc..) in the settings. So if I need hex one moment I have to go into options and change the the format. Then if I need rgb I have to go back into options and change it again.

Also whenever I use the color picker it now puts a huge empty white space above the website I'm working on.

I used to use this all the time when developing websites but now it's useless.

Loved this add-on, but it's now useless. Will change to 5 star once fixed
