<p>The <strong><code>URL</code></strong><strong> </strong>interface represent an object providing static methods used for creating object URLs.</p>
<p>When using a user agent where no constructor has been implemented yet, it is possible to access such an object using the non-standard {{domxref("Window.URL")}} properties (prefixed with Webkit- and Blink-based browser as <code>Window.webkitURL</code>).</p>

<p>{{Compat("api.URL")}}</p>
<p>[1] From Gecko 2 (Firefox 4) to Gecko 18 included, Gecko supported this interface with the non-standard <code>nsIDOMMozURLProperty</code> internal type. As the only to access such an object was through {{domxref("window.URL")}}, in practice, this didn't make any difference.</p>
<h2 id="Chrome_Code_-_Scope_Availability">Chrome Code - Scope Availability</h2>
<p>To use from chrome code, JSM and Bootstrap scope, you have to import it like this:</p>
<pre class="brush: js notranslate">Cu.importGlobalProperties(['URL']);
</pre>
<p><code>URL</code> is available in Worker scopes.</p>
