grammarly does not work with firefox.

some times will edit your words into some blst that you even don't think of ...

I can't take Grammarly any more. I spend more time fixing Grammarly notifications that are errors than my own spelling and grammar mistakes. I've switched over to LanguageTooler and absolutely love it. I've been a Grammarly customer when Grammarly first came out. It was great back than. But, it's A.I. is more of a headache than a helper.

Was the great app until choosing their people filtering policy.
