I wholeheartedly agree with this solution with the additional possibility that you cookie the user's choice. Solutions like firefox plugins are fine for you and me, but not for the remedial computer users who mistype their passwords in the first place. On my sites, the vast majority of customer service calls/emails are people who can't log in, simply because they can't figure out how to type in their passwords correctly (we don't even have a attempts limit - they can try as many times as they like).
