It asks me to login but never lets me login.

Does not work... It says "Grammarly is active, but key features are missing" I cleared cookies, all datas, re-installed plugin, ... always same with macOS 11.0.1 - Firefox 84.0.2, That's really annoying for this such a cool thing.

I am not being able log into the Grammarly account in the add-on, in Firefox.

Doesn't work whatsoever.

Not working. Latest Firefox on Mac.

This extension on Firefox behaves erratically. Meaning, I typically have to go into Markdown Mode for Grammarly suggestions and corrections to "stick" to my postings. The Grammarly extension used with Google Chrome works without issue. I wish this extension installed with Firefox worked the same.

Garbage. Doesn't know grammar. Stupid suggestions. And buggy as fuck.

good but expensive.

Didn't work at all...

Badly-written 36 MB addon which stops working after it is disabled and re-enabled, requiring reinstall. The company has very aggressive marketing and forces people to install this addon. In contrast, Linguix grammar checker works online without any addon. This addon integrates everywhere, thus sending anything what is typed to Grammarly. They don't care if it contains sensitive info.

Once you turn it off? You have to re-install it to turn it back on

not correcting properly

It used to work on my Auctiva page but all of a sudden stopped working a few days ago. I re-installed - still not working. Still works on my Yahoo mail, but not on Auctiva.

Grammarly is not appearing in Firefox despite my carefully following the directions. It used to work well, but I cannot access Grammarly now.

when I copied rom gmail and pasted to my facebook, it seems that parts of the text were recopied or corrupted.

Very Slow, no local chaching. Often updates and insets the corrected word into the wrong part of the text box.

Grammarly performs very poorly.

For instance, according to Grammarly the following nonsense has:
- Correctness: Looks good
- Clarity: Very clear
- Engagement: Very engaging
- Delivery: Just right
