Changes for Web developers
element.outerHTMLproperty is now supported on HTML elements.
XMLHttpRequestsupports HTML parsing.
- Removed support for using the
withCredentialsattributes when performing synchronous requests. Attempting to do so throws an

window.navigator.mozVibrate()method lets you vibrate the device where supported; this is implemented as

- Both the protocol and the API has been updated to the latest draft of the specification and the API has been unprefixed (see bug 666349 and bug 695635 ).
- Previously, messages sent and received using WebSockets in Firefox were limited to 16 MB in size; they may now be up to 2 GB (although memory capacity limitations may prevent them from being that large, Firefox supports it).
- The change in Firefox 8 that removed support for double quote characters as delimiters for RFC 2231 and RFC 5987 has been reverted, as this broke some sites, including Outlook Web Access.
- The user agent string in HTTP headers now includes an identifier that lets the server know if the Firefox accessing it is a phone or a tablet.
