    New Web Developer Features

    HTML

    Elements with tabindex="-1" should be focusable
    Elements with a negative tabIndex attribute can now have focus, even though they are not in the tab order.
    Object should submit
    In accordance with the HTML4 specification, <object> elements can now be submitted as part of a form.

    CSS

    CSS2 quotes nesting
    Starting with this release, the quotes CSS2 property is fully supported, with the correct quote (depending on the nesting level) used for open-quote and close-quote.
    CSS3 :only-child
    This CSS3 selector allows selecting an element that has no other elements as siblings in the DOM.
    CSS3 columns
    An experimental implementation of the proposed CSS3 multicolumn layout draft. This allows easily doing newspaper-like multicolumn presentation.
    CSS3 overflow-x and overflow-y properties
    These properties can be used to control the overflow behavior in the horizontal and vertical directions somewhat independently. For example, overflow in the horizontal direction could be hidden while overflow in the vertical direction can be scrolled to.
    CSS3 cursors
    More mouse cursor names are now supported.
    URI values on CSS cursor properties
    On Windows, OS/2 and Linux (Gtk+ 2.x) one can now use an arbitrary image as the mouse cursor while a given DOM node is being hovered. Any image format supported by Gecko can be used for the image. (SVG, animated GIF, and ANI cursors are not supported.) See Using URL values for the cursor property for a description of the feature.
    -moz-outline-radius
    CSS outlines can now have rounded corners.
    CSS outline property
    CSS outlines can now be used. These differ from borders in that they don't affect the page layout.
    Counters in CSS-generated content
    CSS2 counters are now completely supported (the implementation doesn't match the current CSS2.1 draft, but matches the upcoming one). This allows automatic numbering of sections, headings, and so forth via stylesheets.

    JavaScript and DOM

    Array extras
    New methods have been added to the Array object to facilitate common tasks. See JavaScript 1.5 Array Object.
    document.open("text/plain")
    Text written in new documents created with document.open("text/plain") is now treated as text rather than HTML, so line breaks will remain intact and tags will not be parsed.
    XML Events
    "XML Events" is a W3C specification to provide XML languages with the ability to integrate declarative event listeners and event handlers.
    Cancelling keydown
    Cancelling the keydown event now properly cancels any corresponding keyup/keypress events, per the DOM specification.
    Accessibility APIs for DHTML
    Mozilla now allows DHTML authors to add role and state semantics to custom elements, and exposes that information via MSAA and ATK.
    DHTML Performance Fixes
    A number of changes were made to significantly improve DHTML speed and smoothness.

    Graphics

    SVG Support
    SVG is W3C specification providing resolution-independent scalable vector graphics, along with a DOM. A technology preview of native SVG support is included in this release. Currently a subset of SVG 1.1 Full, missing functionality includes filters, declarative animation, and SVG defined fonts.
    <canvas> Support
    <canvas> is a scriptable drawing surface for dynamically creating bitmap graphics. For a further introduction, see Drawing Graphics with Canvas.

    Miscellaneous

    Support HTTP/1.1 408 response code
    A persistent connection is now correctly closed when a 408 response code (Request timeout) is received. The request is retried in a new connection.
    URIs always sent as UTF8
    URIs are now always sent to the server as UTF8, regardless of the linking page's encoding. This fixes images and links on sites with non-ASCII filenames.
    XForms support
    The W3C's XML Forms language allows writing complex forms in XML, and includes features that regular HTML forms do not have, such as client side validation against XML Schema and XML submission/retrieval. Support for XForms comes as an extension, see Mozilla XForms Project Page.

    New Extension Developer Features

    Hidden referrer column for history
    Extensions can now access the referer information for pages stored in the browser history. This feature can be used to provide alternate history views and other useful functionality. Bugzilla bug
    API for prioritizing HTTP connections
    The Mozilla networking library now supports the prioritization of connections to a specific server. See nsISupportsPriority. Bugzilla bug
    API for managing user and UA stylesheets
    Extensions can now register stylesheet URIs as additional user and UA stylesheets. This means extensions no longer have to try to edit userContent.css to add styling (say for XBL binding attachment) to web pages. See Using the Stylesheet Service.
    API for configuring proxies
    It is now possible for extensions to easily override the proxy configuration without affecting user-visible preferences. See nsIProtocolProxyService, nsIProtocolProxyFilter, and nsIProtocolProxyCallback. Bugzilla bug
    Dynamic Overlays
    Loading of XUL overlays after the document has been displayed is now supported. See nsIDOMXULDocument. Bugzilla bug
    E4X
    The Mozilla JavaScript engine now supports ECMAScript for XML (E4X), a draft ECMA standard that adds native XML datatypes to the language and provides operators for common XML operations. See the ECMA specification. Bugzilla bug
    Translucent Windows (Windows/Linux)
    On Windows and Linux, XUL windows with a transparent background are now supported. This allows whatever is below the window to shine through the window background.
    Adding tokens to the User-Agent string
    It is now possible for applications, extensions, and vendors to all add tokens to the User-Agent string (using default preferences) without overwriting each other. See documentation. Bugzilla bug
    Toolkit chrome registry
    Chrome registration has been significantly improved to use simple plaintext chrome registration manifests, and no longer keeps the chrome.rdf/overlayinfo cache. See Chrome Registration.
    Extension Manager
    • It is now possible to have Extensions outside the profile and application Extensions directories.
    • Installing extensions can now be done by dropping an XPI into the profile or application Extensions directory.
    • Uninstalling an Extension now involves simply deleting its folder from the profile or application Extensions directory.
    New Preferences bindings
    These new bindings make it easier to create preferences windows for extensions. The new preferences windows support instant-apply behavior, which is enabled by default on Mac and Linux.
    API for implementing new command-line switches
    An API has been introduced so that extensions can easily handle complex command-line flags. This API will be stable and frozen for 1.1. See the interfaces nsICommandLine and nsICommandLineHandler.
    XTF Support
    The eXtensible Tag Framework allows adding support for new namespaces using XPCOM components to Mozilla (written in JavaScript or C++). For example, the Mozilla XForms Project uses XTF to add support for the XForms namespace. See XTF Home Page

    New Browser Features

    Improved Preferences

    Instant Apply behaviour on Linux and Mac
    Changes made in the Preferences window now apply immediately, in line with typical behaviour in other Mac OS X and GNOME applications. This changes conforms with the Apple and GNOME Human Interface Guidelines.
    Searchable download actions manager
    It is possible to search the Download Actions manager by file extension or description.
    Searchable cookie manager
    Cookies can be searched by hostname/domain and cookie name, and are organized by hostname in a tree format instead of a flat list.

    Deployment

    Firefox MSI package
    The new MSI installation package facilitates distibuted installation and provides greater flexibility to network administrators wanting to deploy Firefox in a corporate environment.
    Support for profile "temp" directory on local filesystem
    It is now possible to store the network cache (copies of visited webpages) and the XUL fastload cache (precompiled user interface code) on a local disk, while keeping the rest of the profile data on a network drive. This will increase performance and reduce network traffic for users in a network environment.

    Other

    "Sanitize" privacy feature
    The "Sanitize" feature provides an easy way to quickly remove browsing history, cookies, cache, saved form information, and other personal data. The items to be removed can be customized, and the feature can be activated using either a keyboard shortcut or through a menu item.
    Image thumbnails as tab icons
    When viewing images, tab icons now display thumbnails of the displayed image.
    Fast back (and forward)
    This very experimental feature allows much faster session history navigation. The feature is off by default but can be enabled for testing purposes by setting the browser.sessionhistory.max_viewers preference to a nonzero number.
    Anonymous FTP login failure behaviour
    FTP users are now prompted to input a name and password if anonymous access fails.
    CSS at-rule for matching on site/document URL
    The new @-moz-document rule gives users the ability to match page objects per-site, using CSS. This makes it possible to include site-specific rules in user style sheets (userContent.css). David Baron's post to www-style explains how the rule can be used.
