This is the most amazing spell checker and useful add-on on the internet. Good onya Firefox! Thanks.

I think It's better than Grammarly.

This add-on works very well for me. The comma suggestions are just what I was looking for :).

Works great, and has great features, recommended.

Ich bin hochzufrieden mit dem tool. Es hilft mir auf vielen Seiten die ich bearbeite.
Vielen Dank

Es un corrector excelente y me ha evitado publicar con errores gramaticales, imperdonables. Lo recomiendo.

Trés bien

Edit: I checked on other browsers and found that firefox was the one logging out all the properties of the event parameter passed into the eventListener, it was not your addon, sorry

Excellent application for grammar verification.

Not just functionality but an absolute joy to use.
