For new users make sure you "auto saved" all your documents every minute as it freezes and crash your web pages very often. When crashed a yellow bar appeared that reads "a script "Grammarly for Firefox" is slowing down your browser, temporary disable or stop it." If you are lucky only one tab crash, if not all and never respond again. Got to turn off power to restart your computer (very annoying).

I don't understand why some people give a 1-star score
if you know better alternative please share it with us

It is a nice service but from a month ago its started to crash some pages.
