Grammarly is injecting some sort of weird metadata into posts on some forums. In particular, the last one was on TechNet. Here is the link to the post in question. https://social.technet.microsoft.com/Forums/windows/en-US/cdfe7d70-2ff7-4025-87db-e26d452d27a2/how-can-i-completely-disableremove-readyboost-in-windows-81?forum=w8itprogeneral
It is very annoying, I am going to have to disable Grammarly for the time being which pisses me off because it's awesome.

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

nice!

With the last update on Firefox, I can't seem to find this extension. It's not working.

Sure helps out thanks.

Crap, Rubbish, money taken for no perfomance, try replying to a post, no show. I would like my money returned.G. Henderson.

Grammarly is great and works perfectly for me. Notifys you of the simplest mistakes and things you may want to double check. While it may noe always be 100% accurate, it's great how it points things out so you take the time to check whether you're right or not.

One star is only to grab attention. this is a 5 star plugin but recently since firefox quantum, the plugin is unable to correctly underline the words (misaligned underlining)

Honestly, Awesome thanks fireFox . Lot of Love

its OK, they spam you way too much

I love grammarly but unfortunately the extersion is really bad on Firefox quantum.

Doesn't work with various sites i frequent.

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

Absolutely great! Best thing to come along since Bullfighter from Deloitte & Touche back in the 90's! It will definitely help improve your writing skills.
