setConsumeRollupEvent( consume )- Return type: no return value
Controls whether or not the event that caused the popup to be automatically dismissed (or "rolled up") should be consumed or be dispatched as a normal event. If a non-default behavior is desired, this method should be called immediately prior to calling openPopup or openPopupAtScreen.
Possible values for consume are:
ROLLUP_DEFAULT- The default for the current platform.
ROLLUP_CONSUME- Consume the rollup event.
ROLLUP_NO_CONSUME- Don't consume the rollup event.
Note: This method did not work on Mac OS X prior to Gecko 1.9.2 (Firefox 3.6).
