One of my favorite add-ons. Works great and is essential for writing in Firefox!

Its cool

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's a really helpful extension and it corrects a lot of stuff that I usually just leave as is and forget about, I highly recommend this even to people who think they are experts at grammar, because I thought I didn't need it but a lot of mistakes have been caught by it and proven me wrong.

Worked Great with Chrome! Testing it out on Firefox...

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

Good app

The best option out there, a real shame is not available in more languages.

French grammar version?

Although it was in "featured" section, but when it asks for permissions, it asks to access all my data on all website which is quite suspicious. Will it access my passwords and login details as well as bank information as well?

Spell check is highly inaccurate even allowing for differences in US & UK spelling.
Grammar check is a hoot.

Last and most critical application inserts promo codes that really dick up the results to the point I'm getting error messages for the extra codes.
