Great add on and pity so few reviews are written.
In short, you install it, use it to check your Croatian spelling it gets updated or works with every new Firefox release and what else is there to say about a language add on? It is perfect for the job! Kudos to the author who gives this out freely and to the benefit of all.

Uredno radi i ima pristojnu bazu riječi. Rado ću počastiti autora ručkom za trud ukoliko se uspijemo naći.

Hvala na trudu :)

Hvala.
