It's buggy in GitHub.

Helps you sound smart when people read what you have typed.

Grammarly is great but the extension is missing a critical feature - it cannot be disabled by default for all websites and only enabled manually for some on which it is needed, let it be gmail, reddit or facebook. Switching it off for every website except some is troublesome and disabling extension until it is needed is even more so. It would be also great to have a way to enable spell checking for websites on which it does not work by default - maybe context menu item "Enable Grammarly" - for example hukd.com comments don't work with grammarly plugin. Please fix it and 5 star rating will be the well deserved rating.

"Grammarly will make sure your messages, documents, and social media posts are clear, mistake-free, and impactful."

Impactful is a neologism that was coined by people whose command of English vocabulary wasn't sufficiently fluent enough to come up with a more appropriate accepted usage word or words. Is this the quality of grammatical assistance I can expect from this add-on?

More dumbing down that's been tarted up as progress...

I love this plugin, but for a couple of days now it is terribly slowing Firefox Quantum (57.0.1) down. Please fix this. I can't use it as it is now functioning.

Je n'ai utilisé ce module qu'une seul fois donc!

its OK, they spam you way too much

It's okay, helpful to know what you want to do!

It's great, but sometimes (too often) tells me I have a grammar error when it actually isn't.

Not as good as LT, which catches more errors and do not need registration.

Well, it's not bad either, I'll give it a 3-star.

Grammarly for Firefox works as well as it does on most other platforms except for Desk.com. When I use it at desk.com as an agent it will create this blank white space above where I type that covers the email address sections so I am unable to change anything. I know it's grammarly because if I disable to extension the white space covering the To: section goes away.

It is fine when it kicks in automatically but it sometimes doesn't work even though it is turned on.

French grammar version?

This is nce n gd

I am typing this in order to see if it actually works. It kind of does, however, not very good. I have to find out mistakes myself in order for it to be fixed. The free account simply gives you options to fix but not fix it directly for you. You still have to have a brain

Has got some uses but the rules are not always correct. Not mentioning the paywall the add-on has some annoying bugs that stopped me using it: the overlay Grammarly textbox breaks out of most modern-css text inputs and also hides the typing caret until you disable the add-on
