It's confusing. I have installed the extension, now it says I should create an account and log in. So I've done that. Now it says I have to download another app. I don't want to install anything from someone I don't trust. So I can't activate it unless I download software, or am I just missing something? It I have to download something, why doesn't it say this, why does it only say I have to create and account and log in. Very confused.

Once you use it (by copy pasting my text into their website as it's not really an extension (if so it doesn't work on the text field where I'm testing it)), you be teased with improvements you have to pay to see. And the price is 30 $ a month. This wasn't communicated at all when I signed up.

I find all of this very deceptive. Why not be upfront about all the steps you need to take, and the price you need to pay, in order to use this comfortably. As a free extensions, this is pretty bad.

Doesn't work anymore

Uses 500MB of memory and slows down firefox. Not worth it.

This add-on makes Firefox slow at every web page.

Does not underline or flag mistakes on all pages or forms. The default Firefox spell check does. Bummer.

Been years and still the same bug I posted about 2 years ago. It still doesn't work right. Was working for a day. Now that Firefox updated it is not working well at all. It is jumping all over the place and screwing up words. I can't even put spaces where I want as it makes the cursor move to where the red is and even deleted a paragraph on me. What is going on? I have now disabled it. This is a bad bug. Also when it corrects it will actually duplicate the exact paragraph a 2nd time in the middle of one and then throws me right off. This is supposed to help wtih Dyslexia?? No way. Way worse! Looking for something else.

Simply does do not do anything. I cannot see any difference with turned on and off

It has slowed my email progress. My email is now running slower, firefox is slower. I don't know how to remove it from firefox?

I don't know why but this Firefox extension doesn't work on Firefox latest version 61. On Chrome it just works fine.
"Grammarly is active but key features are missing", even if I have a premium account.

Not working anymore... not sure why.

Grammarly is great. Wish I could get the app to download. Grammarly page for Firefox only offers download for Firefox which I already have!!

Doesn't support anything

Can't get to the page to put in a work so that I can see if it is correct. Frustrating to keep clicking page after page and getting only another page.

Doesn't work at all.

..won't open..and can't figure out why

Working fine with Chrome and but now I switched to Firefox..its not working..I am payed customer. I don't know it is firefox problem or Grammarly problem...Fix it!

After working fine for over a year, it just abruptly stopped with the latest Firefox update. This is very disappointing. I have a 64-bit computer and Mozilla won't allow me to download the 32-bit version, which I have on my other computer. Since it works on that, I would have to assume the issue is with the 64-bit version. If they don't stop pulling this crap with add-ons, I will have no choice but to make Chrome my default browser.

No longer works for FaceBook or Twitter. Finding an alternative.

Ce module n'est pas fait pour la langue française

You need an account to do anything, even to toggle it on and off without needing to go into your add-ons tab. It'll display a number in a red bubble just to get your attention when there is nothing wrong with your paper or message.

Does not work on Firefox. When I use Chrome the add on worked fine, but now that I use Firefox the addon does not work. Very disappointed as I am a paying customer of Grammarly.

can't find the spot tq get into my profile

The extension GREATLY slow-down whole firefox (tested with profiler, and official Gecko Debugger) on FF61, 62, 63 (nightly). Can't recommend, because it's slowdown page loading super very much. And without the extension overall browser performance greatly increased. Fix perfroamance issues first before releasing this addon.

this add on is so disorganized and so difficult to install, after installation it forced me to register, which I did not want, received no feed back and no indication I could use it, then kept on pushing me to install the MS APP version, additional to the non existent feed back forced me to remove the add on.
