Easily one of the best grammar checkers for everything from long-form narratives to a letter to your dear old mom.

Best app to check grammar.

From the description of the add-on, it is not clear why it requires the permissions "Get data from the clipboard", "Input data to the clipboard" and "Access browser activity during navigation"?

Easy to install and allows you to use your time more efficiently doing the things you need to get done, rather than proof reading and re-reading over text.

I really loved how this add-on helps. But suddenly it started to block online payments on some sites and auth on microsoft.com. That's really strange. Can't specify any error since it's just blocks page from loading. And console doesn't tells anything reasonable. Last error messages are: "GEThttps://login.live.com/favicon.ico"(404) and "Error: Promised response from onMessage listener went out of scope". Regarding last one even when I load microsoft.com with this add-on disabled, this error still exists but site works normally. So, I guess this error means nothing.

This Grammar Checker really helped me. But suddenly out of nowhere I couldn't send emails out of Firefox. If I turn all my add-ons off I can send, so turning them on one at a time and emailing in between each time, (refreshing email page each time), it didn't take long to come to this program. I hope they can fix it soon! Outside of this problem the add-on is GREAT!!!

I would give it ZERO stars if I could. It constantly highlights perfectly spelled words, and then wants me to upgrade to a pro version for better results. IDIOCY!

Easy to use and surprisingly powerful. Actual legit extension that isn't trying to scrape my data while being super practical. I use it to setup multiple template responses and to help out with my poor writing.
