Colorpick Eyedropper v0.0.2.39 
A simple eye-dropper & color-picker tool allowing you to select color values from webpages.
This extension is in BETA which means you should not install it unless you expect to find and report bugs.
Reporting bugs is not the same as writing a bad review. Bugs should be reported here with the text "Firefox Colorpick Bug".
If you want a finished extension use Colorzilla instead.
An official port of the Google Chrome Extension of the same name.
