The setup page checks for $_POST["redirect"] to see if you've clicked the "sign in with Twitter" button. However, Firefox (because the Twitter button is an image) supplies redirect_x and redirect_y $_POST variables but not $_POST, meaning that the request isn't detected as having had the Twitter button pressed. This works in Chrome.
