About this extension
Description

Moonsun Toggle provides a simple and elegant way to switch between your favorite Firefox themes with a single click. Instead of navigating through deep menu settings or the
"Add-ons and themes" page, you can now toggle between your personalized look, the official Dark theme, and the official Light theme directly from your toolbar.

Whether you need to reduce eye strain as the sun goes down or want to switch back to your vibrant custom theme for work, Moonsun Toggle makes it effortless.

Key Features:
* 🔄 Seamless Cycling: Cycle through your custom theme, Dark mode, and Light mode in one click.
* 🧠 Smart Memory: The extension automatically remembers your active custom theme and includes it in the rotation.
* 🌓 Adaptive Tooltip: Hover over the icon to see your current theme and what the next click will switch to.
* 🚀 Lightweight & Fast: Built with modern Manifest V3 standards for minimal impact on browser performance.
* 🔒 Privacy-Focused: No data collection, no tracking, and no unnecessary permissions.

How it works:
The extension identifies your currently active theme. If you are using a custom theme (or the system default), it sets it as your "Base" theme. Clicking the button then
rotates you through:
1. Dark Theme (Built-in)
2. Light Theme (Built-in)
3. Your Custom Theme (Saved automatically)
