I use Firefox all the time, because I consider it to be a superior browser to Internet Explorer. The built-in spell checker works fairly well, and allows you to right-click misspelled words for correct spelling suggestions. You can also add words to the dictionary by right-clicking, to take care of all of the crazy werewolf terminology. The Firefox spell checker is similar to the Microsoft Word spell check, in that it puts a squiggly red line under any misspelled words in any open text fields.
