It asks me to login but never lets me login.

Does not work... It says "Grammarly is active, but key features are missing" I cleared cookies, all datas, re-installed plugin, ... always same with macOS 11.0.1 - Firefox 84.0.2, That's really annoying for this such a cool thing.

I have been using this addon for quite a long time now and I find it really helpful. But the issue I am facing is, it won't log me in. Although, I am logged in to the website but in the text boxes, it never logs in. I hope you get my point and fix the issue.

Grammarly is well worth the low cost for the complete version. It is usually accurate in performing the daunting task of finding and correcting grammatical errors. Its better than most. I use it all the time.

I've heard many others say this too, I cannot sign in.

I am not being able log into the Grammarly account in the add-on, in Firefox.

Doesn't work whatsoever.
