Definitely helped in avoiding basic mistakes during internet chat and mail sessions. Also helps in drafting professional articles in wordpress.

It has helped me overcome simple grammar mistakes I often used to commit. I suggest you add few features from the paid versions.
Thank you, Team Grammarly!

nice automatic beaviour

Excellent. The best I Ever use.
but is it for free?

Helpful. Hope it isn't responsible for "adding on" to my postings, ie: completing them with irrelevant pop up material.

Most useful to have! Thanks! :)

A+

Works great

In love with Grammarly since I've tried this amazing product <3

However, one thing about this addon is really annoying - lack of ability to disable addon on a certain webpages. I have to disable it completely if it causes issues with some WYSIWIG online editors and then enable it again. Please add an option to disable it selectively.

p.s. As a Ukrainian, I am proud of this talented dev team!

It works as advertised and I find it valuable when writing email and updates to clients, but it's input window is laggy and it consumes a huge amount of CPU (i7, 8G RAM) to the extent that it's near pinning the CPU when I'm typing an email sometimes. I've used the plugin on Chrome and never noticed it being resource hungry, so there's something odd here.

I've found it useful to turn it off in the input window via it's widget, type the message, and then turn it on and let it parse the entire message rather than live as I type. That seems to work well.

Paid for the premium service and the apps included are all buggy and useless. Will not keep you logged in to your account even with Premium, does not work as it says it will across all web writing. Stick with the free version as the apps are overpriced and don't work properly! Also no app for mobile which is crazy for the prices they are asking for.

Not that great. I was writing a paper for a theatre class, and it told me that I needed to change all instances of "theatre" for "theater." It doesn't really help any more than any built in grammar device anyways, at least the free version doesn't.

Again and I again the customer service told me to uninstall and re-install it.
It doesn't work.
If even it is already enabled Mozilla propose me to install it like it was not present yet.
I am premium client. Disappointing.

Perfect

The drop-down is empty... i am a little bit disappointed. Hope the Tech group can fix this...

It is a great idea but it does not work for me unfortunately, it keeps telling me to log in even though I have logged in a thousand times and I cant get it to review anything I write.

It does not work. Please fix it.

Drop down box is blank. Doesn't run in my FF browser. Have to open the site to check my writing. Have to use Chrome to edit web pages on the fly.

I love this product, it catches things I would never have caught. On the other hand it sometimes misses items but nothing is perfect.

I love this tool, and use it daily. It has forced me to become a better writer. The only complaint is the cost is very high.

LUCKY ENOUGH TO GET IT. NOT ADAPTABLE TO CHAOTIC CIRCUMSTANCES, WONT INSTALL TO FIREFOX ONLY FREEZES ONCE DOWNLOAD IS COMPLETED, NO PROPER RESOURCE FOR OFFLINE USE OR DOWNLOAD. HOW DO YOU EXPECT PEOPLE TO PAY FOR WHAT THEY CANT USE?!!!

Always need to login after every time opening of Firefox. Sometime shows error free, sometimes shows error for some same sentence. After selecting their suggested correction, it pastes the whole sentences again. So disturbing. I can't found any problem in the Chrome edition though.

It's a great add on but doesn't work on every textbox, even isn't working while I type this although the size and sort are OK. Works on whatsappweb making the textbox bigger (adding blank lines). I'll keep it for Gmail spelling check!
