A dynamic Firefox theme that continuously cycles through colors. Available in Firefox Add-ons.
Chromatastic was originally created for the Firefox Quantum Extensions Challenge. I wrote a blog post detailing my experience.
This GIF shows the speed of the color transitions, which occur slowly and smoothly
rather than jumping from color to color.
This extension requires Firefox 115 and above. Install the extension from this Add-ons page.
I use the Node version specified in .tool-versions. Run yarn start to start
development.
To generate a ZIP file for uploading to Add-ons,
run $ yarn run release.
