Rated 4 out of 5 stars

Just switched from Colorzilla because I only use the inspector/eyedropper. The ease of use and simplicity of Rainbow Color Tools is a lot better. The only criticism I have is that I should be able to close it using the Escape button, but that's a minor issue.

This review is for a previous version of the add-on (1.1.1-signed.1-signed).
