Quiet VowelCount Panel od Ronadl

Quiet VowelCount Panel adds a minimal toolbar popup that lets users paste or type text and instantly see the number of vowels (AEIOU) and total length.

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.
