Dialog width is not working in FireFox

Dialog width is not working in FireFox

HI,

I have this dialog :

  2. dialog = $("#dialog-form").dialog({
  3. autoOpen: false,
  4. height: 500,
  5. width: 720,
  6. modal: true,
  7. buttons: {
  8. "Create Rename Rule Type ": addUser,
  9. Cancel: function() {
  10. dialog.dialog( "close" );
  11. }
  12. },
  13. close: function() {
  14. form[ 0 ].reset();
  15. allFields.removeClass("ui-state-error");
  16. }
  17. });


It's working fine in Chrome, but not in Firefox.
thanks.
