It is really helpful, double tap to access definitions and synonyms is awesome. expect some more basics freemium features.

Grammarly for Firefox seems tired and slow compared to Chrome. In Chrome, Grammarly is red hot fast and accurate. I have trouble finding how to set it up and control it in Firefox. It could be just me, but I don't think so.

Works for basic spelling and punctuation; not so good at advanced grammatical constructs--given that "grammar" is most of its name, that's a problem.

Great for basic corrections. Very, very buggy for Wordpress websites. Some corrections do not take and adds junk code to your web pages. See this site for junk code example: https://searchfacts.com/grammarly-adds-junk-code/

Was very happy with it until Twitter changed its format and Grammarly for Firefox stopped working altogether. (Also have G for Windows installed). While social networking isn't the only reason I use it, it is a major part of it and seeing that there hasn't been an update for a year and a half I'm wondering if there's a solution or workaround coming.

Good spellchecker but needs an option to run only on-demand. Running it on every input on every page is just distracting and annoying. Removing...

There is some bug related to https://www.sciencedirect.com website. Everytime I visit it I am forced to disable Grammarly add-on, because of a message saying that the add-on is slowing down the website and because of a dramatical increase of the CPU load. Please fix this.

I loved it on the desktop but it doesn't work on Firefox for Android

Sometimes it interferes with some websites. Eg Microsoft Technet forums and it's a pain in the ass!

The *only way* is to open Menu > Add-ons > select this add-on > Disable it (temporarily)

It would be nice if there's a right-click shortcut to disable it temporarily.

I'm very happy to have Grammarly for some things. It gives me an extra layer when writing or editing articles in Word or online. But when I'm working online, it causes problems in my browser (Firefox). I haven't tried using it with other browsers such as Chrome, but I will. I keep getting a message that Grammarly is causing pages to hang or otherwise have problems. So I stop the program, and I'm guessing it starts again and has the same problem. Otherwise, I appreciate Grammarly. It's not perfect, and you shouldn't expect it to be, because it's not human. You need to be able to see when it's on the wrong track. It's made me more aware of habits I have and of things I had missed in English class way back in high school.

The add-on is very useful. Their services are good. However, this extension is not the best in terms of affecting the user's performance. Google search times nearly double after enabling this extension. Should they optimize this issue, the extension would be amazing.

When it works it works well. My problem is that it is not installed in my programs and I must sign on each time to activate/start the service. Were it in my list of AP's and on my task bar my rating would be a 5-star, N'other words, although it seems to be writer error, I have blamed the AP for the problem. Yes, the last sentence was humor.
