this add-on is really impressive, I am trying to learn English with its writing, it has its algorithms for various levels of people, and its suggestions for correcting words or sentences are too good

"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...

Just doesn't work. I've had to go back to Chrome.

It's there, but says it's active but no functionality and asks me to log in. I log in and nothing changes Still doesn't work.

Really Helpful when writing on Firefox :)

This does not work in the new Firefox. I won't keep my login and just shows a grayed out wifi icon and keeps saying refresh your browser. Please fix this issue.

always loved firefox

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.

convenient and non intrusive :)

It does not work in half the the site I use.

You still need to have a basic understanding of grammar to be sure the recommendations don't change the meaning of your sentence, but this extension far outperforms the built-in spelling and grammar checkers.

I really like this tool but it uses 100% of my CPU when it's on. I can toggle it on and off to see the CPU graph go from 25% to 100% over and over. It causes FF to freeze up with the little hourglass that never goes away. I have to use file manager to kill FireFox and restart since nothing works when it's frozen.

Addon can't remember login status between sessions - to repeat same login procedure to fix one-two mistakes - pretty annoying stupidity.
