Gecko notes

compositionupdate events are fired before editor contents are actually changed; that is, the value of an editable element has not yet been changed when compositionupdate event handlers are called. Starting in Gecko 12.0 (Firefox 12.0 / Thunderbird 12.0) , input events are fired while editing is underway, after the contents of the element are changed. This lets you get the updated contents while editing is underway.
