CSS

  • Added support for mongolian, disclosure-open and disclosure-closed counter styles in list-style-type (bug 982355 and bug 1063856).
  • Fixed CSS animations with empty keyframes rule so they also dispatch events (bug 1004377).
  • Added support for rebeccapurple, a new <color> name defined in CSS Colors level 4 (bug 1024642).
  • Our experimental implementation of CSS Fonts Level 3 progresses. Its activation is governed by the the layout.css.font-features.enabled preference, enabled by default in Nightly. Newly implemented features are:

HTML

  • Added the experimental support for <picture> element (bug 870022), behind the dom.image.picture.enabled preference (off by default).
  • The <label>, especially without a for attribute, doesn't apply anymore to a <input type=hidden> field (bug 597650). The previous behavior wasn't spec compliant.
  • The link annotation noreferrer has been implemented on <a> elements. <a rel="noreferrer"> will not include the URL of the referrer in the HTTP request sent to fetch it (bug 530396). Note that this work only for in-page links, not for linked clicked via the UI, like via contextual menus.
  • On Android, support for two new values for the name attribute of <meta> has been added: msapplication-TileImage and msapplication-TileColor (bug 1014712).
    Example:
    <meta name="msapplication-TileImage" content="images/benthepcguy-144.png"/>
    <meta name="msapplication-TileColor" content="#d83434"/>
