Très pratique pour corriger les petites fautes au quotidien. J’apprécie particulièrement le fonctionnement local et discret. Un excellent outil pour Firefox !

Le module détecte correctement les erreurs que j'ai testées. Mais c'est dommage que je ne vois pas les erreurs dans la zone de saisie. Est-ce que j'ai manqué quelque chose ?

Outil extrêmement pratique. Est-il utile ? Non, il est indispensable à qui veut écrire sans faire, trop, de fautes.
