GREAT! But users having issues NEED to read the description Rated 5 out of 5 stars

Awesome add-on and great that it is a WebExtension. Thank you! And people who are reading this and having issues, PLEASE read the description....Contact Colorzilla's dev to get your issues fixed, do NOT post your problems in a review, you fools. That's why you don't get support and then you complain when the dev doesn't fix his stuff.

Color Picker now crashes Firefox Rated 5 out of 5 stars

Have been using Colorzilla for MANY years. Now for the first time the color picker (eyedropper) not only fails to operate, it locks up Firefox.

Latest Firefox release.

Some really unfortunate changes since v3 Rated 3 out of 5 stars

I have been using and loving this extension in its previous versions for as long as i remember using firefox (since version 0.6, fifteen years ago or something like that).

It has been most helpful. Always handy to have a page color picker AND a "color manager" to quickly find a color when working on a webdesign.
I found myself using the color manager even in other situations, because it was just there... always a firefox instance opened, colorzilla a click away.

Now, since version 3, it is sadly UNUSABLE!
You can still approximately use the color picker to copy a webpage color but colorzilla is now NOT A PERSISTENT WINDOW, it disappears once it loses focus.
This means you can't see the result of your colors fiddling persistently anymore, colorzilla just SHUTS DOWN AND LOSES ALL CHANGES.
How dumb is that?

I have been forced to install another color manager: Sharp Color Picker. This one has a permanent window and won't cut your throat behind your back.

Please, use your extension once in a while, and see for yourself how you made it unusable for all your real users out there.

Anyway, thanks a lot to you for years of good service, it is just sad you made this unfortunate step.

much improved over 3.1 Rated 4 out of 5 stars

i would like to amend my 1-star review of version 3.1 with a few comments on version 3.3, which is a substantial improvement.

1) web page color analyzer.

don't know if previous versions of colorzilla included this feature, because i never saw/used it, but this feature alone is worth 5-stars, as it lays out the entire CSS color palette for a given site, allowing you to easily choose from the entire set of colors currently in use on whatever site you're working on. no need to resample every time (or indeed, any time). huge thumbs up on either adding this feature or making it more visible.

2) Don't move document down when sampling.

another thumbs up, here, and a big reason i've amended my review. you have to check a box in options to enable this feature, but it speeds up the time it takes for the color picker to activate, and doesn't cause strange interactions on pages that use iframes.

3) Automatically start eyedropper when main button is clicked.

uncheck this option in your prefs, and you get single click access to all of colorzilla's options/features, just as in previous 2.x versions. the trade-off is that you don't have single-click access to the eyedropper, but this doesn't bother me too much, especially with the availability of the web analyzer tool.

i haven't had a chance to test out how well the "copy special ..." feature works, but being able to copy rgba values is a boon, if it works.

the numerous bug fixes also make for a more stable plug-in.

colorzilla almost lost me with their 3.1 update, but 3.3 has restored my confidence in this indispensable developer's tool.

so why not 5 stars?

because it's a new version and i haven't had time to truly put the plug-in through it's paces, i don't know whether the bugs that affected my workflow are well and truly gone, or whether or not new bugs have appeared. i hope for the best.

developers should not shy away from installing colorzilla though, which appears to me to have reclaimed its place as one of, if not the most useful firefox plug-in for developers.

Not So Essential Any More Rated 2 out of 5 stars

This addon used to be a life saver but, since the new UI and method changes, it's just awful.

Simplicity used to rule but, now, it's trying to do too much and getting most of it wrong.

Such a pity, but it's now time to find a repacement.

Essential tool Rated 5 out of 5 stars

I've been using ColorZilla for years. It's one of those small widgets I just can't live without. Easy to use. Precise results. Absolutely recommended for frontend developers.

A phenomenal tool Rated 5 out of 5 stars

I have been using ColorZilla for years now and it is really good.
Easy to use, never breaks and the latest release has some really good features - especially the new sampling modes

Keeps me straight with the webites I have open Rated 5 out of 5 stars

I open a lot of website at once and the color keeps me straight with what website I need to go to next.

Was Great! Can still be Rated 3 out of 5 stars

I have used ColorZilla for years, and as a web developer, it is an indispensable tool.

However, the new UX is not as easy to work with. I honestly prefer the separate window so I can work across multiple FF tabs and with my css files. I think this is where most of the disappointment comes from others.

The added features were nice, but please if possible, bring back the old separate UX/UI window to help keep our workflow .. flowing without having to reopen that panel every time.

Thank you!

Must have! Rated 5 out of 5 stars

Best color picker EVER!
