I'm giving this a one-star review because it promises to work with a simple click of the grammarly icon--but it doesn't. I want to use it to check my WordPress posts before I post them, and it 'says' it's free, but it doesn't work. I keep getting stuck in an endless loop of 'it's installed but something is missing,' so I log in, and it doesn't tell me what to do to figure out the missing link. I'v given the extension permissions, I've restarted Firefox, but grammarly still doesn't do anything. I'm disappointed. I really wanted to like this. But if it takes me more than five minutes to make it work, it's not worth my time. If I have to purchase premium in order to use this feature, it needs to say so up front.

Great add-on. The only thing that would make it perfect was that it worked on more areas (e.g, Google Docs) and had more features moved from premium to regular (e.g, plagiarism).

Excellent product.... Though has some issues in some Facebook areas, like not showing when replying to a comment

I am really really annoyed by the intrusive ads depicting "happy students" and other left-wing nonsense shouting at me from Every media that I use. Besides, Grammarly is a YAS (Yet Another Spellchecker) only with hype. There are plenty of other hype-free spellcheckers available for Firefox and I will choose one that doesn't annoy me rather than one that I can not relate to At All and one that doesn't bring any novel functionality to the table!!!! If I were on an uninhabited island and Grammarly was the last ever available spell checker, I'd rather go without any spellchecker than touch Grammarly with a barge-pole (even if it's a very long barge pole)!!!! I find Grammarly totally useless and unnecessary... I think I've made myself clear enough?

Makes you make less typos. Handy app when free but can bug you to update.....

Many features only in Pro version.

Grammarly will help you communicate more effectively. As you type, Grammarly flags mistakes and helps you make sure your messages, documents, and social media posts are clear, mistake-free, and impactful.
