Silent MoodSlider Panel от Sidi

Silent MoodSlider Panel adds a minimal popup panel to the Firefox toolbar with a small slider interface for quick mood checks.

The extension runs fully offline and does not request any browser permissions.
It does not collect, store, or transmit any user data, and it does not interact with websites or browsing activity.

All functionality is bundled locally inside the add-on package, making it lightweight, privacy-friendly, and easy to review.
