At last a spell checker that works.

Surpreendente! Obrigado por adicionar a língua portuguesa.

Este Add On de Firefox es el paraíso para los que no tenemos buena ortografía, lo recomiendo 100%

Awesome add on

Multi language perfection.

Отличное приложение! Помогает

I use to use Grammarly, but there were some issues that i didn't like, like autocorrecting while typing. Which messed up my typing.
I've been very happy with Grammar and Spell Checker, I'll never switch back.

It works like a charm! During the day I constantly jump from language to language, this plug-in is essential to me, it keeps my texts quality consistent. I just hope they will make the plus version available also though the LibreOffice plugin.
