Works smothly, roughest part was adding to dictionary Rated 5 out of 5 stars

Great extension. Never had a grammar checker in Firefox before and it works very well. The only problem was clicking on 450 words to add into the dictionary -- this one uses cookies, and not persdict.dat in the Firefox profile. I moved "ignore always" to the top of the context menu with the "Menu Editor" extension click on marked word with mouse in right hand, click on "Home" then "Enter" with left hand. I sure am glad everyone uses real dictionaries now when I did this 25 years ago I had to type or paste over 7000 words to our main dictionary and compile it.
