 - The {{ domxref("selection") }} object's [`modify()`](/en-US/docs/Web/API/Selection/modify) method has been changed so that the "word" selection granularity no longer includes trailing spaces; this makes it more consistent across platforms and matches the behavior of WebKit's implementation.
 - The {{ domxref("setTimeout()") }} method now clamps to send no more than one timeout per second in inactive tabs. In addition, it now clamps nested timeouts to the smallest value allowed by the HTML5 specification: 4 ms (instead of the 10 ms it used to clamp to).
 - Similarly, the {{ domxref("setInterval()") }} method now clamps to no more than one interval per second in inactive tabs.

 - The {{ domxref("Blob") }} and, by extension, the {{ domxref("File") }} objects' `slice()` method has been removed and replaced with a new, proposed syntax that makes it more consistent with [`Array.slice()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/slice) and [`String.slice()`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/slice) methods in JavaScript. This method is named `mozSlice()` for now.
 - The value of {{ domxref("window.navigator.language") }} is now determined by looking at the value of the `Accept-Language` [HTTP header](/en-US/docs/Web/HTTP/Headers).
 - The {{ domxref("Element.prefix") }} property is now read only, as required by the DOM specification.

-The XMLHttpRequest API enables web apps to make HTTP requests to web servers and receive the responses programmatically using JavaScript. This in turn enables a website to update just part of a page with data from the server, rather than having to navigate to a whole new page. This practice is also sometimes known as {{glossary("Ajax")}}.

-The [Fetch API](/en-US/docs/Web/API/Fetch_API) is the more flexible and powerful replacement for XMLHttpRequest. The Fetch API uses {{jsxref("Promise", "promises", "", "nocode")}} instead of events to handle asynchronous responses, integrates well with [service workers](/en-US/docs/Web/API/Service_Worker_API), and supports advanced aspects of HTTP such as [CORS](/en-US/docs/Web/HTTP/CORS). For these reasons and more, the Fetch API is usually used in modern web apps instead of XMLHttpRequest.

 ## Concepts and usage
 
 The central interface in the XMLHttpRequest API is {{domxref("XMLHttpRequest")}}. To make an HTTP request:
 
 1. Create a new `XMLHttpRequest` instance by calling its {{domxref("XMLHttpRequest.XMLHttpRequest", "constructor", "", "nocode")}}.
-2. Initialize it by calling {{domxref("XMLHttpRequest.open()")}}. At this point you provide the URL for the request, the [HTTP method](/en-US/docs/Web/HTTP/Methods) to use, and optionally, a username and password.

 3. Attach event handlers to get the result of the request. For example, the {{domxref("XMLHttpRequest.load_event", "load")}} event fires when the request has successfully completed, and the {{domxref("XMLHttpRequest.error_event", "error")}} event fires in various error conditions.
 4. Send the request by calling {{domxref("XMLHttpRequest.send()")}}.
