Это экспериментальная технология
Так как спецификация этой технологии ещё не стабилизировалась, смотрите таблицу совместимости по поводу использования в различных браузерах. Также заметьте, что синтаксис и поведение экспериментальной технологии может измениться в будущих версиях браузеров, вслед за изменениями спецификации.
The URL interface represent an object providing static methods used for creating object URLs.
When using a user agent where no constructor has been implemented yet, it is possible to access such an object using the Window.URL properties (prefixed with Webkit-based browser as Window.webkitURL).
Properties
Implements properties defined in URLUtils.
URLUtils.href- Is a
DOMStringcontaining the whole URL. URLUtils.protocol- Is a
DOMStringcontaining the protocol scheme of the URL, including the final':'. URLUtils.host- Is a
DOMStringcontaining the host, that is the hostname, a':', and the port of the URL. URLUtils.hostname- Is a
DOMStringcontaining the domain of the URL. URLUtils.port- Is a
DOMStringcontaining the port number of the URL. URLUtils.pathname- Is a
DOMStringcontaining an initial'/'followed by the path of the URL. URLUtils.search- Is a
DOMStringcontaining a'?'followed by the parameters of the URL. URLUtils.hash- Is a
DOMStringcontaining a'#'followed by the fragment identifier of the URL. URLUtils.username- Is a
DOMStringcontaining the username specified before the domain name. URLUtils.password- Is a
DOMStringcontaining the password specified before the domain name. URLUtils.originТолько для чтения- Returns a
DOMStringcontaining the origin of the URL, that is its scheme, its domain and its port.
URLUtils.searchParams- Returns a
URLSearchParamsobject allowing to access the GET query arguments contained in the URL.
Constructor
URL()- Creates and return a
URLobject composed from the given parameters.
Methods
The URL interface implements methods defined in URLUtils.
URLUtils.toString()- Returns a
DOMStringcontaining the whole URL. It is a synonym forURLUtils.href, though it can't be used to modify the value.
Static methods
URL.createObjectURL()- Returns a
DOMStringcontaining a unique blob URL, that is a URL withblob:as its scheme, followed by an opaque string uniquely identifying the object in the browser. URL.revokeObjectURL()- Revokes an object URL previously created using
URL.createObjectURL().

[1] From Gecko 2 (Firefox 4) to Gecko 18 included, Gecko supported this interface with the non-standard nsIDOMMozURLProperty internal type. As the only to access such an object was through window.URL, in practice, this didn't make any difference.
[2] This feature is implemented under the non-standard name webkitURL.
Chrome Code - Scope Availability
To use from chrome code, JSM and Bootstrap scope, you have to import it like this:
Cu.importGlobalProperties(['URL']);
URL is available in Worker scopes.
