Grok Cosmic Theme door RatioWorks

Grok Cosmic Theme is an unofficial Firefox customization extension by RatioWorks for personalizing the Grok interface.
Choose from built-in or uploaded wallpapers, customize primary and secondary text colors, change the Grok hero logo tone and transparency, adjust accent colors, and enable OLED, glass, glow, blur, and other visual effects.
Custom wallpapers are processed locally. Settings and exported theme profiles remain on the user's device unless the user manually moves an exported profile file. The extension contains no RatioWorks analytics, telemetry, advertising, or tracking.
Includes quick presets, full reset controls, and profile export/import for transferring a setup to another Firefox installation.
