I used to love this browser extension! It was my favorite way to block sites that distracted me from work. Yet for some reason, it stopped working. I have uninstalled and reinstalled, tried all sorts of things and it still doesn't work anymore. I'd love to keep using it, but I don't know what else to do.

Lo que me gusta; Es totalmente gratuito, no es necesario registrarse, no es necesario pagar por funcionalidades "Premium" y es sencillo de entender y configurar con 2 clics.
