[1] Before Gecko 51.0 (Firefox 51.0 / Thunderbird 51.0 / SeaMonkey 2.48) Gecko implemented a -moz prefixed pseudo-class called :-moz-placeholder, which was later replaced by a ::-moz-placeholder pseudo-element. The standard pseudo-class got implemented in bug 1069012.
[2] Support for this pseudo-class is requested at the Microsoft Edge Developer Feedback page.
