<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 moved either on the <code>HTMLHyperlinkElementUtils</code> mixin, or directly on the interface.</p>
