+<p>[1] 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>[2] From Gecko 26 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.</p>
+
+<p>[3] Before Gecko 49, results for URL using the <code>blob</code> scheme incorrectly returned <code>null</code>.</p>
