In this way I learn English laguage better step by step. I'm enjoyed of Grammarly.

My only issue with this extension is on a Windows PC in Firefox it locks up my whole system. I cannot even get into taskmgr. what I assume is happening it's trying to update the extension. For now I disabled this extension and will just go with Windows text grammar checker.

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

I wish I could be more a help to firefox instead of just a consumer.

I love it even if I can't spell or punctuate or correct my grammar on my own anymore!!! Can't live without Grammarly.

Doesn't work at all.

YES

It works Great. A+++
