Important

Due to new Firefox add-on developer requirements and restrictions requiring all future add-on development to be done using WebExtensions technologies, ColorZilla for Firefox has been re-written from the ground up to comply with the new requirements.

This new version retains all the functionality, but there might be minor UI/UX and other differences.

Please contact us to report any issues.
