Doesn't work in Firefox 58.0.2 (64-bit) Manjaro Linux

Bugs! Break the editor of https://forum.theodinproject.com

Straight up DOES NOTHING on Firefox Nightly 60.0a1 (2018-02-24) (Hasn't worked before this version either)
When I click the icon it always says "Grammarly is active, but
key features are missing" and prompts to sign in. When I click on sign in it just opens the Grammarly page showing that I AM signed in.
That is the only place where it works.

Update:
Still the case on Firefox Nightly 68.0a1 (2019-04-12) (32-bit).
The grammarly icon on text fields is there, but it never seems to figure anything out. Trying to sign in via that icon doesn't work either. After putting in my login details and pressing "login" the button gets a spinning loading icon that spins for a while then stops. Nothing happens.

I'll be using "LanguageTool" instead. At least that works.

This has always worked really well in Chrome, but there seems to be a breaking bug in Firefox that just makes all text entry hang.

Пустое и бесполезное

Publicidad engañosa, con pocas posibilidades. Sobrevalorada. Para ser un programa de traduccion, esta todo en ingles y nada más.

SOME KIND OF HUSTLE? WHEN YOU DOWNLOAD AN EXTENSION ON FF YOU DON'T USUALLY QUESTION IT'S AUTHENTICITY BUT SOMETHING ABOUT THIS IS VERY FISHY. IT DOESN'T WORK RIGHT OUT OF THE BOX YOU HAVE TO "SIGN UP" FIRST.

Bloaty - causes firefox to take up a VAST MAJORITY of memory. Plus, even with a gaming desktop, the corrections show up later and conflict with existing red lines, making it sort of redundant. Always seems to be popping up in my face and forgetting my preferences. Annoyingly showing on EVERY youtube video I watch. O_o

On Firefox 57 in Ubuntu Budgie, while using this extension it makes all text invisible

This software is a piece of crap. It selects a word it thinks is misspelled and will NOT allow you to manually re-position your cursor. Meanwhile you keep typing thinking the cursor is where you last put it, and then find that Grammarly has completely jumbled and rearranged what you typed cuz it re-inserted the cursor where it chose. Like I said, it's junk. The only reason I gave it 1 star was because I couldn't give it zero stars, or better yet, minus stars. Also, I can't uninstall it by navigating from my Control Panel, cuz it doesn't even show up there under Programs and Features. Which I'm guessing is a problem that Mozilla has created; why would you do something silly like that? Don't you folks comprehend that that is typical virus behavior? Do you WANT people to associate your product with being malware??? And then there's the whole speed thing, who needs slower computing?

And I would really appreciate someone telling me how to uninstall this garbage from my computer.

Grammarly has slowed my PC. I wish to delete. How do I go about that?

Если я ничего не напутал, а это вряд ли, то дополнение проверяет только американский, британский, канадский и австралийский английский, а другие языки посылает лесом!

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.

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.

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

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.

Crap, Rubbish, money taken for no perfomance, try replying to a post, no show. I would like my money returned.G. Henderson.
