Quiet TextMeter Panel от Chesser

Quiet TextMeter Panel adds a small toolbar popup that allows users to paste or type text and instantly see character and word counts.

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

All functionality is self-contained inside the add-on package, making it minimal, privacy-friendly, and easy to review.
