New version of ColorZilla – v2.5

A new version of ColorZilla (v2.5) is now available. This version is still beta, so please let me know if you find any issues.

New in this version:

  • Color Picker Dialog:
    • New Photoshop-like ‘new/current’ color split panel
    • New smooth color map and color slider controls (based on John Dyer‘s JS Color Picker)
    • Experimental Lab and CMYK color spaces support
    • New ‘Eyedropper’ button allows sampling document colors while working in Color Picker
  • Eyedropper:

    • Limited Flash sampling support
    • Allow scrolling the document while color sampling
  • Web Color Analyzer: better color palette sorting
  • Firebug integration: fixed Firebug ‘Inspect’ panel opening for the last sampled element

By the way, if you missed the last v2.2 version, it added support for Ubuntu Linux 64bit, Firefox 4, HSL colors and more.

As always, you can download the latest v2.5 beta, along with the latest stable v2.2 version at

    Thanks for the update.

    After using this indispensable plug-in for years, it’s so great to be able to say…….THANK YOU!

    One of my favorite extensions. Thanx!

    Doesn’t seem possible to hide it any longer. SHIFT+ESC merely toggles the crosshair.

    Same here. Ever since updating to v2.2, the option to hide ColorZilla has been removed… can we get this functionality added back in?

    Thanks for the great job, though!

  5. reisio Says:

    Yes, it even works in my Linux builds again. :)

    @reisio, @Jimmy – check out the latest beta here:, it restores the ‘Hide’ option :)

  7. Jimmy Says:


    Thanks! I’ve installed the latest beta!
    Just a thought about the hide button, but I thought it would be better located on the main menu (of the app button), probably right below “Help” rather than in the Options menu. I’m sure there are those like me who’d use ColorZilla when they need it (easy open using Shift+Esc), but all other times like to keep it hidden to lessen clutter on the browser. Making the Hide button easy to select like an “Exit” button seems more convenient since it might be used often.

    Just a thought. Keep up the great work!

    I agree with Jimmy, and would go further to not make people hit ‘OK’ on a notification dialog every time they want to hide it _BUT_ dude, thanks, you rock.

    Is it possible that I am using colorzilla for more than two years now :) I love it !
    It is the first addon I install after fresh installation.

    Thank you for your hard work.

    This is my very favorite Firefox add-on. Unfortunately, when I installed 4.0b7 yesterday, Colorzilla has one tiny problem. It gets shoved over into the right part of the add-ons bar instead of its usual left position. As such, it has no room to expand and display the color values detected onscreen. I sincerely hope this can be fixed soon!
