I'm confused! Is this a free use, or are we now going to have to pay for it? I have used this product off and on. At times I downloaded it and it never worked. Now it calls for Grammarly Prime to be offeredat a monthly use.

Now I find out, that I have downloaded this three times and it has never work, even when I updated it to Grammarly for Windows.

Now I'm here to download it again for Fire Fox, Will it work this time?
