Silent TabTimer Panel 作者： Darius

Silent TabTimer Panel adds a minimal toolbar popup with a small timer interface for quick timeboxing.

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.
