The usual way of cancelling the default action for an event is to return
false from the event handler; try changing your "return true;" in the
above to "return false;" and see if that helps.

If that doesn't work, as you say it's for Firefox, try visiting the
Firefox/Mozilla developers site:
<http://developer.mozilla.org/en/docs/DOM:event#Introduction>
explains the "preventDefault" method, which might do what you want.

HTH,

Nick.
