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.
