Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

The mozbrowserselectionstatechanged event is fired when the text selected inside the browser <iframe> content changes. Note that this is deprecated, and current implementations should use mozbrowsercaretstatechanged instead.
