It never gave me corrections. Even when I blatantly misspelled a word. It just took up space. It said to log in to enable more things then I logged in and it did not realize that.

I have logged into Grammarly.com, but the extension does not recognize my log in. Therefore, this extension does not work!

recent update made it slow and not reliable

Cannot login to Grammarly. Login uses all available memory. Have to reboot. Damn and I have a premium accoun too!

Can't sign in.

Grammarly's Add-on is incredibly unreliable with logins and in no way compatible with Firefox containers or multi-container plugins.

I have logged into Grammarly through grammarly.com, but the extension does not recognize my log in.

Cannot login

Impossible to sign in. Clicked "log in" button, nothing happened. Please fix this, Grammarly Premium is not cheap.

Super buggy login. And even after I login to Firefox extension, the extension doesn't work properly with my Grammarly premium account. Tried to reinstall. Created a ticket with no response from Grammarly. Maybe this review will get them to contact me finally to resolve. Frustrating

Already logged in but still prompts me for it, doesn't work at all.

Does not login. How long does it take for them to unfu-ck things?

I'm unable to login to the plugin. Works OK on Chrome.

Grammarly on firefox doesn't work. I'm thinking of going back to chrome where these things at least work properly

This app used to be quite good. Now, it is simply garbage. It prompts me to login in order to use it. I do. And then it prompts me to log in again. And again, and again, and again. It never actually does its job.

Doesn't worn on Firefox.

Extension doesn't recognize the user is logged in. Its Terms of Service are also ridiculous.

"By uploading or entering any User Content, you give Grammarly (and those it works with) a nonexclusive, worldwide, royalty-free and fully-paid, transferable and sublicensable, perpetual, and irrevocable license to copy, store and use your User Content (and, if you are an Authorized User, your Enterprise Subscriber’s User Content) in connection with the provision of the Software and the Services and to improve the algorithms underlying the Software and the Services."

It no longer works in Firefox. After logging in, the extension still didn't work

The add-on will not sign in. When I click "Log In," I am taken to the "My Grammarly" page of the app/website.

Doesn't work (doesn't notice you're logged in).

Grammarly apparently had my previous review deleted for stating that they are 'basically a key-logger that owns everything you write.'

So, I'll paste their actual terms of service in and let you make your own informed decision.

'By uploading or entering any User Content, you give Grammarly (and those it works with) a nonexclusive, worldwide, royalty-free and fully-paid, transferable and sublicensable, perpetual, and irrevocable license to copy, store and use your User Content (and, if you are an Authorized User, your Enterprise Subscriber’s User Content) in connection with the provision of the Software and the Services and to improve the algorithms underlying the Software and the Services.'
