Senior Dev Contribution Graph Editor od Michael Hobbs

Senior Dev Contribution Graph Editor is a small add-on that lets you modify the contribution graph on GitHub's user profiles.

Features:

• adjust the contribution graph colors
• run predefined animations over the graph

Features can be adjusted in this extension's options menu accessible via Firefox's Add-ons Manager.

The following browser permissions are requested:

• Run only on pages on GitHub.com.
• Access the "storage" JavaScript API, only for persisting and restoring the extension's own settings (such as the chosen colors).

No personal data is collected, stored, or anything for any purpose.
