The compositionend event is fired when the composition of a passage of text has been completed or cancelled (fires with special characters that require a sequence of keys and other inputs such as speech recognition or word suggestion on mobile).
 The event was fired in versions of Gecko before 9.0, but didn't have the DOM Level 3 attributes and methods. Gecko doesn't support the locale attribute for trusted events yet. However, this value can be set via initCompositionEvent() when creating untrusted events.

Why does MDN look different?
MDN is changing to focus just on documenting web technologies. All the same great content is still here; we’re just changing some visual elements and navigation, to help you more quickly find the web technology docs you’re looking for.
But don’t worry, MDN and Mozilla are still together! In fact, we're updating MDN’s look to reflect Mozilla's new logo and colors.
