About this extension
This add-on brings an animated koi pond to your Firefox toolbar! Current features include:
While the add-on is enabled it sets your theme; turn it off to go back to your previous one.
- Four different animated looks (Dawn, Day, Dusk, Night).
- A day/night cycle that automatically applies the matching look, following your local sunrise and sunset.
- Your choice of how it changes: follow the sun (enter your location for exact times), set your own times, or keep just one of the four looks.
- An Eco mode that animates at a lower frame rate to use less CPU and battery.
- Animations pause if your system is set to reduce motion, and the pond is wide enough for 4K displays.
While the add-on is enabled it sets your theme; turn it off to go back to your previous one.
