Silent MiniMeter Panel автор Prada

Silent MiniMeter Panel adds a minimal toolbar popup with a small progress meter and a slider to adjust the percentage value.

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.
