Mozilla Firefox comes with a spell checker for ensuring that you have written all the words correctly in boxes and forms(In feedback or commenting or in post) on any website.Whenever you will write some incorrect word in the form then it will be underlined in red.
By default,the Firefox Language is set to United States English which may annoy other users who use other English like United Kingdom English,Australia English or Canada English as their primary language.To solve this problem you can install other Language-pack(includes dictionaries of different languages) and later change the Language settings of your browser to work the spell checker as expected.
