Works intermittently on Firefox Quantum 62.0.3 (64-bit), therefore I question the point of paying for a premium service.

Love it when it works. It seems that it is so schizo on FaceBook and it is suppose to work on this page and it does not. I contacted their customer service and got nowhere quick with them. Either the customer service people are not kept aware as to what is going on or just simply stonewalling. I give up with Grammarly.

Fine when not logging itself off, which happens frequently- just found and placed the tool bar button which- hopefully- logs me on in a whif'...

It slows down the pc with Premium subs.

I agree with the reviwer who said: In Google Contacts, when Grammerly is active, I can not see my NOTES field because Grammerly conceals it with its badge. It's very irratating to have to click on the grammerly badge to see the note field, which disappears again when I return to the contact view.

It used to work great. But Avast is now blocking it and I can't seem to change it.

This has been working fine for a while, but I had to refresh Firefox for other reasons.
Then it is necessary to re-install the add-ons.
After installing Grammarly, Firefox could not get to any web page I requested.
After disabling Grammarly, Firefox would work without a problem.
Firefox does have a spell checker so I will stick with that to minimize having too many add-ons.

Running Firefox Quantum 61.0.1 (64-bit).

When I log into my PC as a different user they both play well together. Go figure?

Awesome

It is good, but buggy as hell. The administration refuses to work on these bugs. This extension is very buggy on Twitter if it works at all (up to what browser). If it is buggy on one service, I don't trust it to work on others.

Have to frequently reinstall. Sometimes a Blank screen sometimes refuse to make correction even it recommends . Just not very reliable same or similar issues with extensions for Chrome and Safari as well.

Very buggy with latest versions of Firefox. Read the console log as it is beating its brains out to contact an external server that is not responding.

Slows my computer down terribly. I had to turn it off until they fix it.

Also, since it is free, I have concerns that everything I type goes to their server where my data is extracted and sold.

i love how it USED TO WORK. But now it's a piece of crap. I make corrections and they don't not stick. The errors come right back.

The red line supposedly underneath words is somewhere else entirely on the page.

Absolute total buggy garbage and unusable.

Doesn't work with Firefox. What gives?

Poor integration with MyBB fourms.

This add-on doesn't work properly on the latest Firefox.

the add on is very useful but has a very poor integration in FF.

All suggestions are offset from the text making it almost useless in Firefox. The Chrome extension does not have this problem. I love it for Chrome... super helpful. This review is not an indictment of Grammarly, but of their extension for Firefox.

Useful functionality, but introduced lag when typing on some pages (i.e. gmail).
