<p>[1] Starting in Chrome 52, this property was moved to {{domxref('URL')}}</p>
<p>[2] Though not grouped in a single abstract interface, this method is directly available on the interfaces that implement it, if this interface is supported.</p>
<p>[3] From Gecko 22 to Gecko 44, this property was on the <code>URLUtils</code> mixin. It has been moves either on the <code>HTMLHyperlinkElementUtils</code> mixin, or directly on the interface. Also, from Gecko 29 to Gecko 40, the returned value was incorrectly percent-decoded.</p>
