Silent Checkmark Panel de Jolena

Silent Checkmark Panel adds a minimal toolbar popup that lets users toggle between a checkmark and a cross with one click.

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.
