Ligero, Sencillo, Simple y Eficiente. Perfecto, justo lo que estaba buscando.

Stopped working suddenly

Absolutely useless for me. It checks only currently logged-in (in a browser) account.

this is exactly what I need

Simple, Minimal, Lightweight, Perfect. It also shows how many unread emails you have.

This add-on is the best. The rest are either bloated or broken.

Only if this app could show notifications and open in new tab, it would be perfect.
