📃 June 2013 release notes

New in Firefox

The following features are now available in Firefox:

  • background-clip: The background-clip CSS property sets the extent of the background: the padding box, the content box, or the default border box.
  • background-origin: The background-origin CSS property sets the background starting position relative to the border and padding of an element.
  • Clipboard events: The "copy", "cut", and "paste" events fire on elements when the user starts an action with the clipboard.
  • CSS object model: The CSS object model API reads, creates, and modifies CSS stylesheets and inline styles. Also known as CSSOM.
  • <data>: The <data> element links a given piece of content with a machine-readable translation.
  • Notifications: The Notification() constructor shows a message to the user, typically using the notification system of the host operating system.
  • Notifications from service workers and installed apps: Notifications via service worker registration's showNotification() method, sent from installed web applications (for example, saved to the Home Screen on Safari for iOS), show a message to the user, typically using the notification system of the host operating system.
  • @supports: The @supports at-rule applies styles based on a browser's support for CSS features, such as a CSS property and value. Also known as feature queries.
  • <template>: The <template> HTML element holds HTML fragments which you can clone and insert into the document using JavaScript.
  • <time>: The <time> HTML element represents a time, such as a calendar date, clock time, or duration. It may include the datetime attribute to translate dates into machine-readable format.
  • WEBGL_compressed_texture_s3tc WebGL extension: The WEBGL_compressed_texture_s3tc extension for WebGL 1.0 and 2.0 contexts adds S3TC compressed texture formats to compressedTexImage2D() and compressedTexSubImage2D().
  • WEBGL_depth_texture WebGL extension: The WEBGL_depth_texture extension for WebGL 1.0 contexts defines 2D depth and depth-stencil textures.
  • WEBGL_lose_context WebGL extension: The WEBGL_lose_context extension for WebGL 1.0 and 2.0 contexts simulates losing and restoring a WebGLRenderingContext or WebGL2RenderingContext.
  • WebRTC: The WebRTC API establishes real-time communication channels directly between browsers. It is commonly used in video conferencing applications.
