in short: when I use FF3 and submit a form by hitting the enter-key after typing a few characters in an input field, the validator thinks the form is valid even when it's not, and subsequently submits the form.
to see what i mean, go to any jquery.validator demo: http://docs.jquery.com/Plugins/Validation/valid hit TAB until your focused on the single text-input demo form field, type a few characters then immediately hit enter (no tab again; no mouse, etc.). You'll see that the form is submitted even when debug is true! I filed a ticket here: http://dev.jquery.com/ticket/3560#preview doesn't seem to happen on Safari, so it may be a FF3 bug. rather egregious i'd say.
