As of Firefox 51, I intend to unprefix the ::placeholder
pseudo-element on all platforms.

The -moz prefixed version has been active for a long time now, all
browsers support a prefixed version, and WebKit has just unprefixed it
for their test preview of Safari.

I've also recently unprefixed the related pseudo-class,
:placeholder-shown, in bug 1069015.

Bug to enable it: https://bugzilla.mozilla.org/show_bug.cgi?id=1069012

To be clear, the intent here is to support both ::placeholder and
::-moz-placeholder for now, if I understand correctly.
