How do I use the Firefox spell checker?
Firefox automatically checks the spelling of words that you enter in text boxes containing more than one line. As soon as you finish typing a word, it is checked against the words in the installed dictionary. If the word is not found in the dictionary, it will be underlined in red, as in the following example:
- Automatic spell-checking is only turned on for text boxes containing more than one line, where you can enter as much text as you want.
- Not all locales come with a dictionary installed due to licensing reasons.
