Pure trash it doesnt recognize greek lang at all....

The addon is good, but it causes UI freezing, especially on MacOS, and to fix that I need to switch to other application and then back to FF.

So awhile back just staying signed out and taking the few freebies they let you had was enough to let it live sitting there probably harvesting data or extrapolating or whatever word used to obfuscate how my usage gains them something. Then little annoyances grew and festered, like the suggestion popup starting to block more and more of the UI and causing real delays, less of this, more nag, more less, and less and less reasons to keep it around. Welp, one spellcheck and then you be a nagging me boy?! let me show you what ingrates gits when them britches gets too big and your booty ain't paying the rent no moe. Adios Grammar Nationalist Socialists let the purge of all things green begin! Whaaaagh!

Grammarly provides an excellent support for non-native English speakers. Thank you !

Why is this app not working all the time, I pay good money for this and it isn't always available. Do better!!!

Works like half the time. Other times, it adds mistakes, like putting a comma where it shouldn't be.

Use to be a pretty good product. Now, I don't know if it's FireFox or Grammarly, the extension won't even load.

Unbearably buggy in my experience. It constantly desyncs the text its trying to read, or the UI doesn't work at all if clicked on.

awesome and very helpful

Garbage. Makes you constantly log in, but won't actually work on Google Docs or most other things. Even clicking on the extension shows a blank space. Grammarly has abandoned Firefox and should just admit it.
