I have used this add-on several times, only to find that #1) It is the worst spell and grammar checker ever, and often highlights words and grammar that are correct. And #2) It significantly slows down my typing and browser. As soon as I removed it, my typing and browser speed was fine. I would give it NO stars if I could. /// In response to the Developer. It affected all websites I use on Firefox. I've never had issues before, and when I removed your app, the slowdown stopped. As for bad corrections, I no longer use the app, so I do not have screenshots and wouldn't know how to post them here anyway, because there is no way to post photos. Update: 4.25.21 I am going to give it a try again and see what happens. I removed some other add-ons and maybe they were the problem. Will update soon!

This tool prevented me from posting on Twitter over what it listed as grammar errors. When I attempted to override it, I was taken to a website wanting me to buy the premium version. I removed the tool. spell checking and grammatical checkers should only "SUGGEST". Maybe I wanted to be grammatically incorrect.

Does not work with multiple languages in one form.

It recently started making the txt jump around when sending DMs in twitter rendering it unusable. Before that I preferred it to the more popular one

poor and irritating!

Even the premium version does not show simple article mistakes, and also the support team does not answer the questions.

First word I checked said it was too short. Pointless!

Incredible that the "privacy-focused" Mozilla is pushing users to install this app in Firefox. The app sends *everything you write* to this company, and they can do whatever they want with it. Writing a business email with sensitive information in it? Whoops! Just amazing that people fall for this.

Отвратительно! Просто прорва русских слов ему неизвестна. Программа сама себе противоречит и зацикливается в советах, но всегда не правильно.
Если слово чуть сложнее речи дошкольника, то его приходится проверять через гугл и игнорировать ошибку.

Completely context blind. It treats different lines as entirely different paragraphs and doesn't seem to be able to recognize something as simple as the end a sentence. Practically useless.
