ColorZilla now working on Intel Macs!
I’ve just received word from Alex Sirota, that his great Mozilla Firefox and Mozilla Suite extension, ColorZilla, is now working on Intel Macs.
Its task is to assist professional web developers and designers with color related tasks. The feature most of us have used though, was the color picker, which unfortunately stopped working on Intel Macs.

ColorZilla allows you to get a color reading from any pixel in your web browser. You can do all sorts of things, like adjusting the sampled colors and copying them to the clipboard, but those are just two of the color related tasks ColorZilla performs.
