I like the spell check feature of Firefox (and other browsers) but I have learned the hard way that composing lengthy prose in a web browser is a very foolhardy thing to do. Instead, I choose to compose in an offline text editor that - since it is a free evaluation version - does not do spell check . I am placing this blank "text area" here as a convenient spot to paste text for a quick spell check.
