recent update made it slow and not reliable

Cannot login to Grammarly. Login uses all available memory. Have to reboot. Damn and I have a premium accoun too!

Brilliant! Who needs a teacher when there is Grammerly.

Can't sign in.

Grammarly's Add-on is incredibly unreliable with logins and in no way compatible with Firefox containers or multi-container plugins.

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

I have logged into Grammarly through grammarly.com, but the extension does not recognize my log in.

I don't like the way it works

Slows down Firefox massively.
