One of the few extensions I couldn't live without Puntuado con 5 de 5 estrellas

Featuring:
- Easily accessible UI (not only via the addons window "Preferences" button but also via the Tools menu
- Makes life easier for all other addons
- Dedicated help forum with responsive extension maintainer.

I made it a point to install it in all three of Firefox, Thunderbird and SeaMonkey.
