Silent TabTally Panel от Jenny

Silent TabTally Panel adds a minimal toolbar popup with a small counter interface.

Users can increment, decrement, or reset the tally 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.
