some reviews...lol.....I love how people show their basic lack of knowledge and problem solving. Then Quickly blaming devs or products. Which is another reason why so many reviews are tainted these days. This is a dictionary pack, but if you don't know what you're installing, next time a quick search of "Firefox change/add dictionary" would give you answers/understanding instead penalizing the dev and looking silly. Works fine and nothing wrong with this dictionary.
