Color Scheme Toggle per roelleor

Color Scheme Toggle adds a simple toolbar button that switches website color scheme
behavior between two modes:

• Auto: websites follow Firefox’s normal color-scheme behavior
• Auto flipped: websites are forced to use the opposite scheme

This is useful when a site follows the browser color scheme but looks better in the
opposite mode, or when you want a quick way to invert light/dark site appearance without
changing the rest of your browser setup.

Features:
- One-click toggle from the toolbar
- Works with Firefox’s built-in content color scheme setting
- No account required
- No remote code
- No data collection
