Had to open an account just to write that that add-on basically is dead recently. Can't even show basic mistakes and shows mistakes when there aren't any. That add-on is barely working these days.

Also note that Mozilla has removed their "recommended badge" recently for that extension.

It can use up to 15 GB of RAM and crash the entire web browser for no reason. An absolutely NIGHTMARE. It has been like that for a month maybe, what have you guys done with this extention? It's absolutely unbareable that you run out of 32 GB ram when having 10 YouTube tabs opened and messaging your friends on Messenger. I can't give more than 1 start at the moment, this is the worst performance I've ever seen in my entire life.

This is a very useful add-on to Firefox. It's much more than a spelling checker, having a very good grasp of grammar and a reasonable ability to determine which word you meant to type. It's not perfect, but it's an excellent tool, as long as you don't follow it blindly.

Très utile.

Seems to do its job and stay out of the way... key for any grammar and spelling checker. Funnily enough it doesn't work in this box 🤣

Used to be pretty good. But for the last 2 weeks, it has been eating ram until the browser crashes
