- <li>The <code>-moz-initial</code> value has been unprefixed ({{bug("806068")}}). <code>-moz-initial</code> will be kept for a while as an alias; however, authors are strongly encouraged to switch over to <code>initial</code>.</li>
- <li>The CSS {{ cssxref("text-transform")}} property now supports the <code>full-width</code> keyword, which allows a more seamless inclusion of Latin characters in text using ideographic fixed-width characters, like Chinese or Japanese ({{bug("774560")}}).</li>
- <li>The CSS {{ cssxref("page-break-inside")}} has been implemented ({{bug("685012")}}).</li>

This will help make it easier to detect bugs that are caused by mishandling of return values, but may cause existing code to break if it's making incorrect assumptions in this regard.</p>
-</div>
-
-<ul>
- <li><code>getBrowserSelection()</code> now returns the selected text in a text input field. As a result, <code>gContextMenu.isTextSelected</code> will be <code>true</code> when the user selects text in a text input field that is not a password field. ({{bug("565717")}})</li>

-
-<h3 id="SVG">SVG</h3>
-
-<p><em>No changes.</em></p>
-
-<h3 id="JavaScript">JavaScript</h3>
-
-<ul>
- <li>The {{JSxRef("Symbol.prototype.description")}} property has been implemented ({{bug(1472170)}}).</li>
- <li>The {{JSxRef("Object.fromEntries()")}} method has been added ({{bug(1469019)}}).</li>

-</ul>

-<h4 id="Removals_3">Removals</h4>
-
-<ul>

-</ul>
-
-<h3 id="APIs">APIs</h3>
-
-<h4 id="New_APIs">New APIs</h4>
-
-<ul>
- <li>The Shadow DOM ({{bug(1471947)}}) and Custom Elements ({{bug(1471948)}}) APIs have been enabled by default; See <a href="/en-US/docs/Web/Web_Components">Web components</a> for more details.</li>
- <li>The {{domxref("Media_Capabilities_API", "Media Capabilities API", "", "1")}} been implemented ({{bug(1409664)}}).</li>
- <li>The {{domxref("Clipboard", "Async Clipboard API", "", "1")}} has been implemented and enabled by default for all channels ({{bug(1461465)}}). As is the case with Chrome, Firefox currently implements only the {{domxref("Clipboard.writeText", "writeText()")}} and {{domxref("Clipboard.readText", "readText()")}} methods; however, unlike Chrome, <code>readText()</code> is only available in <a href="/en-US/docs/Mozilla/Add-ons/WebExtensions">browser extensions</a>.</li>
- <li>The {{DOMxRef("SecurityPolicyViolationEvent")}} interface is now supported. It allows sending events when the {{HTTPHeader("Content-Security-Policy")}} is violated ({{bug(1472661)}}).</li>
-</ul>
-
-<h4 id="DOM">DOM</h4>
-
-<ul>
- <li>The following portions of the {{domxref("Web_Animations_API", "Web Animations API", "", "1")}} have been enabled by default (see {{bug(1476158)}}):
-  <ul>
-   <li>The {{DOMxRef("Animation")}} properties {{DOMxRef("Animation.ready", "ready")}} and {{DOMxRef("Animation.finished", "finished")}}, specifying the <code>Animation</code> object's <code>ready</code> and <code>finished</code> {{JSxRef("Promise")}}s.</li>
-   <li>The {{DOMxRef("Animation")}} object's {{DOMxRef("Animation.effect", "effect")}} property.</li>
-   <li>The interfaces {{DOMxRef("KeyframeEffect")}} and {{DOMxRef("AnimationEffect")}}.</li>
-  </ul>
- </li>
- <li>The {{DOMxRef("Element.toggleAttribute()")}} method has been implemented ({{bug(1469592)}}).</li>
- <li>The historical, previously non-standard, {{DOMxRef("Event.returnValue")}} property is now supported for compatibility purposes ({{bug(1452569)}}).</li>
- <li>We implemented the {{DOMxRef("Window.event")}} property to improve web compatibility, now that it's become standard ({{bug(218415)}}).</li>
- <li>To bring Firefox into alignment with Edge and Chrome, the {{DOMxRef("NavigatorID.platform", "navigator.platform")}} property now returns <code>"Win32"</code> even when running on 64-bit Windows ({{bug(1472618)}}).</li>
- <li>Prior to Firefox 63, links that open new windows that had <code>rel="noopener"</code>, as well as calls to {{DOMxRef("Window.open()")}} with the <code><a href="/en-US/docs/Web/API/Window/open#noopener">noopener</a></code> window feature enabled would default to having all window features disabled, so that you had to explicitly re-enable any standard features you wanted. Now these windows have the same set of features enabled as any other window, and you need to explicitly turn off any you don't want ({{bug(1419960)}}).</li>
-</ul>
-
-<h4 id="DOM_events">DOM events</h4>
-
-<ul>
- <li>Handling of the <kbd>Alt</kbd> key <em>on the right side</em> of the keyboard has been improved on Windows. If the user's current keyboard layout maps the <kbd>Alt</kbd> key to the <kbd>AltGr</kbd> modifier key, the value of {{DOMxRef("KeyboardEvent.key")}} is now reported as <code>"AltGraph"</code>. This behavior matches the behavior recently introduced in Chrome ({{bug(900750)}}).</li>
-</ul>
-
-<h4 id="Media_Web_Audio_and_WebRTC">Media, Web Audio, and WebRTC</h4>
-
-<ul>
- <li>Microphone access now works simultaneously in multiple tabs, even within the same content process ({{bug(1404977)}}).</li>
- <li>{{DOMxRef("RTCDataChannel")}} has been updated to support the sctp-sdp-21 data format for the data, in addition to the older sctp-sdp-05 format previously supported.</li>
- <li>The {{DOMxRef("ConstantSourceNode")}} node type for Web Audio API now has a default channel count of 2 rather than 1, in order to match the specification ({{bug(1413283)}}).</li>
- <li>The {{domxref("Web_Audio_API", "Web Audio API", "", "1")}} interface {{DOMxRef("AudioScheduledSourceNode")}} (and by extension, all the other node types based on it) now throw the correct exception when a negative value is specified for the node start time. That error is <code>RangeError</code> ({{bug(1413284)}}).</li>
- <li>The minimum and maximum permitted values for an {{DOMxRef("AudioParam")}} object's {{DOMxRef("AudioParam.value", "value")}} have been changed to the minimum negative single-precision floating-point value (-340,282,346,638,528,859,811,704,183,484,516,925,440) and the maximum positive single-precision floating-point value (+340,282,346,638,528,859,811,704,183,484,516,925,440) respectively ({{bug(1476695)}}).</li>
- <li>The {{DOMxRef("SourceBuffer.changeType")}} method, which allows you to change codecs during an active stream, has been enabled by default. This is part of the {{domxref("Media_Source_Extensions_API", "Media Source Extensions API", "", "1")}} ({{bug(1481166)}}).</li>
- <li>The {{DOMxRef("AudioParam.setValueCurveAtTime()")}} method has been updated to correctly accept an array of floating-point values to indicate the parameter's values to change to over time. Previously, it required a {{DOMxRef("Float32Array")}} ({{bug(1421091)}}).</li>
- <li>{{DOMxRef("AudioParam.setValueCurveAtTime()")}} has also been updated to correctly return a proper <code>TypeError</code> when a non-finite value is found in the <code>values</code> array ({{bug(1472095)}}).</li>
- <li>In addition, <code>setValueCurveAtTime()</code> has been updated to ensure that, when the parameter finishes following the specified value curve after the duration elapses, the value of the parameter is set to the last value in the list of values to curve through ({{bug(1308436)}}).</li>
- <li>The <code>RTCRTPStreamStats</code> dictionary has been renamed to {{DOMxRef("RTCRtpStreamStats")}} for consistency with other WebRTC dictionaries and the specification ({{bug(1480498)}}).</li>
- <li>Support for the <code>RTCRtpStreamStats</code> dictionary's {{DOMxRef("RTCRtpStreamStats.kind", "kind")}} property has been added ({{bug(1481851)}}).</li>
- <li>The {{DOMxRef("RTCRtpStreamStats")}} dictionary's {{DOMxRef("RTCRtpStreamStats.isRemote", "isRemote")}} property is deprecated and will be removed in Firefox 65. A warning is now output to console when this property is accessed. See <a href="https://blog.mozilla.org/webrtc/getstats-isremote-65/">this blog post on the Advancing WebRTC blog</a> for details ({{bug(1393306)}}).</li>
-</ul>
-
-<h4 id="Canvas_and_WebGL">Canvas and WebGL</h4>
-
-<ul>
- <li>A new <code>powerPreference</code> context attribute has been added to {{DOMxRef("HTMLCanvasElement.getContext()")}}. On macOS this allows WebGL non-performance-critical applications and applets to request the low-power GPU instead of the high-power GPU in multi-GPU systems ({{bug(1349799)}}).</li>
-</ul>
-
-<h4 id="Removals_4">Removals</h4>
-
-<ul>
- <li>The obsolete and non-standard Firefox-only methods {{DOMxRef("Window.back()")}} and {{DOMxRef("Window.forward()")}} have been removed. Please use the {{DOMxRef("History.back", "window.history.back()")}} and {{DOMxRef("History.forward", "window.history.forward()")}} methods instead ({{bug(1479486)}}).</li>
- <li>The {{DOMxRef("URL.createObjectURL", "createObjectURL()")}} and {{DOMxRef("URL.revokeObjectURL", "revokeObjectURL()")}} methods are no longer available on {{DOMxRef("ServiceWorker")}} instances due to the potential they introduced for memory leaks to occur ({{bug(1264182)}}).</li>
- <li>Since it was deprecated in the specification anyway, the limited support for Doppler effects on {{DOMxRef("PannerNode")}} has been removed from the Web Audio API. The {{DOMxRef("AudioListener")}} properties {{DOMxRef("AudioListener.dopplerFactor", "dopplerFactor")}} and {{DOMxRef("AudioListener.speedOfSound", "speedOfSound")}} have been removed, along with the <code>PannerNode</code> method {{DOMxRef("PannerNode.setVelocity", "setVelocity()")}} ({{bug(1148354)}}).</li>
-</ul>
-
-<h3 id="CSSOM">CSSOM</h3>
-
-<p><em>No changes.</em></p>
-
-<h3 id="HTTP">HTTP</h3>
-
-<ul>
- <li>The {{HTTPHeader("Clear-Site-Data")}} header is implemented and no longer behind a preference ({{bug(1470111)}}).</li>
-</ul>
-
-<h3 id="Security">Security</h3>
-
-<ul>
- <li>Site favicons are now subject to <a href="/en-US/docs/Web/HTTP/CSP">Content Security Policy</a>, if one is configured for the site ({{bug(1297156)}}).</li>
- <li>CSP <code>script-src</code> directive's <code>'report-sample'</code> expression now recognized when generating violation reports. This directive indicates that a short sample of where the violation occurred should be included in the report. Previously, Firefox always included this sample ({{bug(1473218)}}).</li>
- <li>Firefox now uses NSS 3.39 ({{bug(1470914)}}).</li>
-</ul>
-
-<h3 id="Plugins">Plugins</h3>
-
-<p><em>No changes.</em></p>
-
-<h3 id="WebDriver_conformance_(Marionette)">WebDriver conformance (Marionette)</h3>
-
-<h4 id="New_features">New features</h4>
-
-<ul>
- <li>Marionette now returns a <code>setWindowRect</code> <a href="/en-US/docs/Web/WebDriver/Capabilities">capability</a> in the <code>WebDriver:NewSession</code> response that is true if the browser window can be repositioned and resized, which e.g. is the case for Firefox but not any mobile applications ({{bug(1470659)}}).</li>
- <li>Added support for the <code>unhandledPromptBehavior</code> capability, which allows to define a specific <a href="https://w3c.github.io/webdriver/#dfn-user-prompt-handler">prompt behavior</a> of the WebDriver specification ({{bug(1264259)}}).</li>
- <li>Handling of user prompts has been added to the <code>WebDriver:ExecuteScript</code> and <code>WebDriver:ExecuteAsyncScript</code> commands ({{bug(1439995)}}).</li>
-</ul>
-
-<h4 id="API_changes">API changes</h4>
-
-<ul>
- <li>Deprecated command end-points without the <code>WebDriver:</code> prefix have been removed ({{bug(1451725)}}).</li>
- <li>The <code>WebDriver:NewSession</code> command returns recommended strings (<code>linux</code>, <code>mac</code>, <code>windows</code>) for <code>platformName</code> as defined in the WebDriver specification ({{bug(1470646)}}).</li>
-</ul>
-
-<h4 id="Bug_fixes">Bug fixes</h4>
-
-<ul>
- <li>Focus related events were missing on element interaction when Firefox was not running as the top-most application ({{bug(1398111)}}).</li>
- <li>Performing a <code>pointerDown</code> and <code>pointerUp</code> action in a subsequent action sequence could trigger a double click because <code>WebDriver:ReleaseActions</code> didn't reset the double click tracker ({{bug(1422583)}}).</li>
- <li>Executing <code>pause</code> actions repeatedly could cause an infinite hang ({{bug(1447449)}}).</li>
