-
-<h3 id="HTTP">HTTP</h3>
-
-<ul>
- <li>The experimental (and deprecated) <a href="https://en.wikipedia.org/wiki/SPDY">SPDY</a> 3.1 is now disabled by default {{bug(1287132)}}.</li>
- <li>Support for {{HTTPHeader("X-Content-Type-Options")}} has been added ({{bug(471020)}}).</li>

- <li>The {{HTTPHeader("Referrer-Policy")}} header has been implemented {{bug(1264164)}}.</li>
-</ul>
-
-<h3 id="Security">Security</h3>
-
-<ul>
- <li>The {{htmlattrxref("ping", "a")}} attribute of {{htmlelement("a")}} element now abides by the <code><a href="https://developer.mozilla.org/en-US/docs/Web/Security/CSP/CSP_policy_directives#connect-src">connect-src</a></code> <a href="https://developer.mozilla.org/en-US/docs/Web/Security/CSP/CSP_policy_directives">CSP 1.1 policy directive</a> ({{bug(1100181)}}).</li>
- <li>Support for the <code><a href="https://developer.mozilla.org/en-US/docs/Web/Security/CSP/CSP_policy_directives#sandbox">sandbox</a></code> <a href="/en-US/docs/Web/Security/CSP">CSP</a> directive has been added ({{bug(671389)}}).</li>
- <li>It's now possible to set a <a href="/en-US/docs/Web/API/Web_Workers_API/Using_web_workers#Content_security_policy">content security policy for workers</a> ({{bug (959388)}}).</li>
- <li>The {{domxref("Navigator.sendBeacon()")}} method no longer throws an exception if the beacon data couldn't be sent due to a <a href="/en-US/docs/Web/Security/CSP">Content Security Policy</a> restriction; instead, it returns <code>false</code> as expected ({{bug(1234813)}}).</li>
-</ul>
-
-<h3 id="Networking">Networking</h3>
-
-<ul>
- <li>When a error has happened during an asynchronous {{domxref("XMLHttpRequest")}}, the {{domxref("XMLHttpRequest.getAllResponseHeaders()")}} method now returns an empty string ({{bug(1286744)}}).</li>
- <li>Instead of returning a <code>NetworkError</code>, asynchronous {{domxref("XMLHttpRequest")}} that fails for CORS or other network constraints now raises an {{event("error")}} that can be catched like any other error ({{bug(709991)}}).</li>
- <li>{{domxref("XMLHttpRequest.getResponseHeader()")}} and {{domxref("XMLHttpRequest.getAllResponseHeaders()")}} now also return empty headers by default. This can be controlled via the preference <code>network.http.keep_empty_response_headers_as_empty_string</code> ({{bug(918721)}}).</li>
- <li>The <code>only-if-cached</code> option has been added to <code><a href="/en-US/docs/Web/API/Request/cache">Request.cache</a></code> ({{bug(1272436)}}).</li>
-</ul>
-
-<h3 id="DOM">DOM</h3>
-
-<ul>
- <li>The <code>once</code> option for {{domxref("EventTarget.addEventListener()")}} is now supported ({{bug(1287706)}}).</li>
- <li>The interface {{domxref("NodeList")}} are now iterable and the methods {{domxref("NodeList.forEach()", "forEach()")}}, {{domxref("NodeList.values()", "values()")}}, {{domxref("NodeList.entries()")}} and {{domxref("NodeList.keys()")}} are now available ({{bug(1290636)}}).</li>
- <li>The interface {{domxref("DOMTokenList")}} are now iterable and the methods {{domxref("DOMTokenList.forEach()", "forEach()")}}, {{domxref("DOMTokenList.values()", "values()")}}, {{domxref("DOMTokenList.entries()")}} and {{domxref("DOMTokenList.keys()")}} are now available ({{bug(1290636)}}).</li>
- <li>The methods {{domxref("Document.createElement()")}} and {{domxref("Document.createElementNS()")}} now have an optional <code>options</code> parameter for creating <a href="/en-US/docs/Web/Web_Components/Custom_Elements">custom elements</a> ({{bug(1276579)}}).</li>
-</ul>
-
-<h3 id="SVG">SVG</h3>
-
-<ul>
- <li>The <code>allowReorder</code> attribute has been dropped and the behavior it was setting is now the default for SVG {{SVGElement("switch")}} elements ({{bug(1279690)}}).</li>
- <li>The <code>defer</code> keyword for the {{SVGAttr("preserveAspectRatio")}} attribute on SVG {{SVGElement("image")}} elements has been removed to follow the latest SVG2 specification ({{bug(1280425)}}).</li>
-</ul>
-
-<h3 id="Drag_and_Drop_API">Drag and Drop API</h3>
-
-<ul>
- <li>The {{domxref("DataTransfer.items")}} property has been implemented, allowing access to multiple items being dragged and dropped using the HTML Drag and Drop API. To allow this, the {{domxref("DataTransferItem")}} and {{domxref("DataTransferItemList")}} interfaces are now supported as well ({{bug(906420)}}). This is enabled by default.</li>
- <li>The old, obsolete Firefox specific drag and drop API events <code>dragdrop</code> and <code>draggesture</code> are no longer supported. Be sure to update any code still using them to use the <a href="/en-US/docs/Web/API/HTML_Drag_and_Drop_API">HTML drag and drop API</a> ({{bug(1162050)}}.</li>
-</ul>
-
-<h3 id="Pointer_Lock_API">Pointer Lock API</h3>
-
-<ul>
- <li>The <a href="/en-US/docs/Web/API/Pointer_Lock_API">Pointer Lock API</a> is now unprefixed ({{bug(991899)}}).</li>
- <li>Before Firefox 50, <code><a href="/en-US/docs/Web/API/Element/requestPointerLock">requestPointerLock()</a></code> asked for permission using a doorhanger, and pointer lock would not be enabled until the user granted permission. From Firefox 50, pointer lock is like the <a href="/en-US/docs/Web/API/Fullscreen_API">fullscreen API</a>: it's granted immediately, but a notification is displayed explaining to the user how to exit ({{bug(1273351)}}).</li>
-</ul>
-
-<h3 id="IndexedDB">IndexedDB</h3>
-
-<ul>
- <li>A {{event("close")}} event is now sent to the {{domxref("IDBDatabase")}} object when the corresponding database is unexpectedly closed ({{bug(1151017)}}).</li>
-</ul>
-
-<h3 id="Service_Workers">Service Workers</h3>
-
-<ul>
- <li>The {{domxref("WindowClient.navigate()")}} method has been implemented. This method lets you open a specified URL into a client window which is being controlled by the service worker ({{bug(1218148)}}).</li>
-</ul>
-
-<h3 id="WebGL">WebGL</h3>
-
-<ul>
- <li>The {{domxref("EXT_shader_texture_lod")}} WebGL extension has been implemented ({{bug(1111689)}}).</li>
- <li>The texImage methods have been updated for <a href="/en-US/docs/Web/API/WebGL2RenderingContext">WebGL 2</a> to implement PBOs (<code>PIXEL_UNPACK_BUFFER</code>) ({{bug(1280499)}}).</li>
-</ul>
-
-<h3 id="WebRTC">WebRTC</h3>
-
-<ul>
- <li>Adding a track to a {{domxref("MediaStream")}} now generates the {{event("addtrack")}} event as described in the specification. The event is of type {{domxref("MediaStreamTrackEvent")}} and is fired on the stream to which the track was added. You can use either {{domxref("EventTarget.addEventListener", "MediaStream.addEventListener('addtrack', ...)")}} or the {{domxref("MediaStream.onaddtrack")}} property to handle <code>"addtrack"</code> events.</li>
- <li>The {{domxref("MediaStreamTrack")}} interface now supports the {{event("ended")}} event and the {{domxref("MediaStreamTrack.onended")}} event handler.</li>
- <li>Firefox now supports the {{domxref("MediaStreamTrack.readyState")}} property, which indicates whether the track is live or permanently ended.</li>
- <li>The {{domxref("MediaStreamTrack")}} methods {{domxref("MediaStreamTrack.getConstraints", "getConstraints()")}} and {{domxref("MediaStreamTrack.getSettings", "getSettings()")}} have been implemented; these let you get the most recently applied set of customized property constraints and the actual values of all of the track's constrainable properties, respectively. The accompanying data types have been documented as well.</li>
- <li>The {{domxref("RTCDataChannel.stream")}} property has been removed. This was replaced with {{domxref("RTCDataChannel.id")}} in <a href="/en-US/docs/Mozilla/Firefox/Releases/24">Firefox 24</a>, but was supported for backward compatibility. Please be sure to update your code to use the <code>id</code> property if you haven't done so yet.</li>
-</ul>
-
-<h3 id="Web_Audio_API">Web Audio API</h3>
-
-<ul>
- <li>The {{domxref("PannerNode")}} interface now supports the 3D Cartesian space properties for the position ({{domxref("PannerNode.positionX")}}, {{domxref("PannerNode.positionY")}}, and {{domxref("PannerNode.positionZ")}}) and directionality ({{domxref("PannerNode.orientationX")}}, {{domxref("PannerNode.orientationY")}}, {{domxref("PannerNode.orientationZ")}}) of an audio source.</li>
- <li>The interface {{domxref("IIRFilterNode")}}, which implements a general {{interwiki("wikipedia", "infinite impulse response")}} (IIR) filter, has been implemented.</li>
- <li>Throttling in background tabs of timers created by {{domxref("WindowTimers.setInterval", "Window.setInterval()")}} and {{domxref("WindowTimers.setTimeout", "Window.setTimeout()")}} no longer occurs if a <a href="/en-US/docs/Web/API/Web_Audio_API">Web Audio API</a> {{domxref("AudioContext")}} is actively playing sound. This should help prevent issues with timing-sensitive audio playback (such as music players generating individual notes using timers) in the background ({{bug(1181073)}}).</li>
-</ul>
-
-<h3 id="AudioVideo">Audio/Video</h3>
-
-<ul>
- <li>The <code>AlignSetting</code> enum (representing possible values for {{domxref("VTTCue.align")}}) incorrectly previously included the value <code>"middle"</code> instead of <code>"center"</code>. This has been corrected ({{bug(1276130)}}).</li>
- <li>The non-standard and experimental method {{domxref("HTMLMediaElement.seekToNextFrame()")}} now seeks to the next frame in the media asynchronously, rather than synchronously, and returns a {{jsxref("Promise")}} which resolves once the seek is complete.</li>
- <li>The implementation of {{domxref("HTMLTrackElement")}} has been corrected to allow {{HTMLElement("track")}} elements to load resources even if not in a document ({{bug(871747)}}).</li>
-</ul>
-
-<h3 id="Battery_API">Battery API</h3>
-
-<ul>
- <li>The {{domxref("navigator.battery")}} property, which has been deprecated since Firefox 43, is now obsolete and has been removed. Use the {{domxref("navigator.getBattery()")}} method instead to get a battery {{jsxref("Promise")}}, which will resolve when the {{domxref("BatteryManager")}} is available for use; the {{domxref("BatteryManager")}} is passed into the fulfillment handler for the promise ({{bug(12593355)}}).</li>
-</ul>
-
-<h3 id="Files_and_directories">Files and directories</h3>
-
-<ul>
- <li>A subset of the <a href="/en-US/docs/Web/API/File_and_Directory_Entries_API">File and Directory Entries API</a> has been implemented, to improve compatibility with sites that were previously only compatible with Google Chrome ({{bug(1265767)}}).
-
- <ul>
- <li>The asynchronous API interfaces have been implemented, with the caveat that only reading of files is supported; for example, the {{domxref("FileSystemFileEntry.createWriter()")}} method is a no-op.</li>
- <li>These interfaces have been implemented:
- <ul>
- <li>{{domxref("FileSystem")}}</li>
- <li>{{domxref("FileSystemEntry")}} (properties only; the methods have not been implemented)</li>
- <li>{{domxref("FileSystemFileEntry")}} (except for {{domxref("FileSystemFileEntry.createWriter", "createWriter()")}})</li>
- <li>{{domxref("FileSystemDirectoryEntry")}} (except for {{domxref("FileSystemDirectoryEntry.removeRecursively", "removeRecursively()")}})</li>
- <li>{{domxref("FileSystemDirectoryReader")}}</li>
- </ul>
- </li>
- <li>{{domxref("HTMLInputElement.webkitdirectory")}} as well as the {{HTMLattrxref("webkitdirectory", "input")}} attribute of the {{HTMLElement("input")}} element have been implemented; this lets you configure a file input to accept directories instead of files ({{bug(1258489)}}).</li>
- <li>{{domxref("HTMLInputElement.webkitEntries")}} has been implemented; this returns an array of {{domxref("FileSystemEntry")}}-based objects representing the selected items.</li>
- <li>{{domxref("File.webkitRelativePath")}} has been implemented; this contains the path of the file relative to the root of the containing {{domxref("FileSystemDirectoryEntry")}} that was among the items in the list returned by {{domxref("HTMLInputElement.webkitGetEntries()")}}.</li>
- <li>See <a href="/en-US/docs/Web/API/File_and_Directory_Entries_API/Firefox_support">File and Directory Entries API support in Firefox</a> for details about what we do and do not support in this API.</li>
- <li>These APIs are now enabled by default; some were previously available but only behind a preference ({{bug(1288683)}}).</li>
- </ul>
- </li>
- <li>We've implemented {{domxref("DataTransferItem.webkitGetAsEntry()")}} as part of the <a href="/en-US/docs/Web/API/File_and_Directory_Entries_API">File and Directory Entries API</a>; this lets you obtain a {{domxref("FileSystemEntry")}} representing a dropped file ({{bug(1289255)}}). This is enabled by default.</li>
- <li>The <code>HTMLInputElement.directory</code> property, part of the <a href="https://wicg.github.io/directory-upload/proposal.html">Directory Upload API</a> proposal, has been renamed to <code>allowdirs</code> ({{bug(1288681)}}). This property is hidden behind a preference.</li>

However, this didn't resolve all scenarios in which timing-sensitive audio playback (such as music players generating individual notes using timers) could fail to work properly.

- <li>The <a href="/en-US/docs/Tools/Network_Monitor">Network Monitor</a> Response tab now shows a <a href="/en-US/docs/Tools/Network_Monitor#HTML_preview">preview of the rendered HTML</a> — if the response is HTML ({{bug(1353319)}}).</li>
- <li>Cookie information shown in the Storage Inspector (see <a href="/en-US/docs/Tools/Storage_Inspector#Cookies">Cookies</a>) now includes a <em>sameSite</em> column showing what the same-site status of each cookie is ({{bug(1298370)}}).</li>
- <li>The <a href="/en-US/docs/Tools/Rulers">Rulers</a> tool now includes a readout showing the current dimensions of the viewport ({{bug(1402633)}}).</li>
- <li>In <a href="/en-US/docs/Tools/Responsive_Design_Mode">Responsive Design Mode</a>, you can now set the screen dimensions using the cursor keys ({{bug(1421663)}}).

-<h3 id="CSS">CSS</h3>
-
-<ul>
- <li>The {{cssxref("overscroll-behavior")}} property and its associated longhand properties — {{cssxref("overscroll-behavior-x")}} and {{cssxref("overscroll-behavior-y")}} — have been implemented ({{bug(951793)}}), and it has been enabled by default on all releases ({{bug(1428879)}}).</li>
- <li>The behavior of "unusual elements" (elements that aren’t rendered purely by CSS box concepts such as replaced elements) when given a {{cssxref("display")}} value of <code>contents</code> has been updated as per spec ({{bug(1427292)}}). See <a href="https://drafts.csswg.org/css-display/#unbox">Appendix B: Effects of display: contents on Unusual Elements</a> for exactly what the specced behaviors are.</li>
- <li>{{cssxref("position")}} <code>sticky</code> is now supported on appropriate <a href="/en-US/docs/Learn/HTML/Tables">HTML table</a> parts (e.g. {{htmlelement("th")}} elements) ({{bug(975644)}}).</li>
- <li>{{cssxref("calc()")}} is now supported in {{cssxref("&lt;color&gt;")}} values — <code>rgb()</code>, <code>rgba()</code>, <code>hsl()</code>, and <code>hsla()</code> ({{bug(984021)}}).</li>
- <li>{{cssxref("calc()")}} in <a href="/en-US/docs/Web/CSS/Media_Queries">media query</a> values is now supported {{bug(1396057)}}.</li>

-
-<h4 id="DOM">DOM</h4>
-
-<ul>
- <li>The {{domxref("EventTarget.EventTarget()","EventTarget()")}} constructor has been implemented ({{bug(1379688)}}).</li>
- <li>The {{domxref("Response.Response()","Response()")}} constructor can now accept a <code>null</code> value for its <code>body</code> parameter, as per spec ({{bug(1303025)}}).</li>
-</ul>
-
-<h4 id="DOM_events">DOM events</h4>
-
-<p>The {{domxref("Event.composedPath()")}} method has been implemented ({{bug(1412775)}}).</p>
-
-<h4 id="Service_workers">Service workers</h4>
-
-<ul>
- <li>The service worker <a href="/en-US/docs/Web/API/Clients">Clients API</a> can now find and communicate with windows in a separate browser process ({{bug(1293277)}}) .</li>
- <li>Nested about:blank and about:srcdoc iframes will now inherit their parent's controlling service worker. Fixed in ({{bug(1293277)}}) and ({{bug(1426979)}}).</li>
- <li>When a service worker provides a {{domxref("Response")}} to {{domxref("FetchEvent.respondWith()")}}, the {{domxref("Response.url")}} value will not be propagated to the intercepted network request as the final resolved URL.  In the past the {{domxref("Request.url","FetchEvent.request.url")}} was used for this instead.  This means, for example, if a service worker intercepts a stylesheet or worker script, then the provided <code>Response.url</code> will be used to resolve any relative {{cssxref("@import")}} or {{domxref("WorkerGlobalScope.importScripts()","importScripts()")}} subresource loads ({{bug(1222008)}}).</li>
- <li><code>FetchEvent.respondWith()</code> will now trigger a network error if the {{domxref("Request.mode","FetchEvent.request.mode")}} is <code>"same-origin"</code> and the provided {{domxref("Response.type")}} is <code>"cors"</code>. ({{bug(1222008)}})</li>

-
-<ul>
- <li>The {{domxref("MediaStreamTrack")}} property {{domxref("MediaStreamTrack.muted")}}, along with the events {{event("mute")}} and {{event("unmute")}} and the corresponding event handlers, {{domxref("MediaStreamTrack.onmute", "onmute")}} and {{domxref("MediaStreamTrack.onmute", "onunmute")}}, have been implemented. A track's <code>muted</code> state indicates that the track is not currently able to provide media data.
-
- <div class="note"><strong>Note:</strong> The <code>muted</code> state of a track isn't useful for what's typically thought of as muting and unmuting a track. Instead, use the {{domxref("MediaStreamTrack.enabled", "enabled")}} property; setting <code>enabled</code> to <code>false</code> causes the track to output only empty frames.</div>
- </li>
- <li>The {{domxref("RTCRtpReceiver")}} methods {{domxref("RTCRtpReceiver.getContributingSources", "getContributingSources()")}} and {{domxref("RTCRtpReceiver.getSynchronizationSources", "getSynchronizationSources()")}} have been implemented to provide information about the sources of each RTP stream. However, a specification change occurred before release and we have disabled these by default behind the preference <code>media.peerconnection.rtpsourcesapi.enable</code> ({{bug(1363667)}}, {{bug(1430213)}}, and {{bug(1433236)}}.</li>
- <li>The {{domxref("RTCRtpTransceiver")}} interface has now been implemented, since the Firefox implementation of WebRTC now supports transceivers, with <code>RTCPeerConnection</code> and other interfaces updated to use them per the latest specification.</li>
- <li>The {{domxref("RTCPeerConnection.addTransceiver()")}} method has been added. In addition, the behavior of {{domxref("RTCPeerConnection.addTrack", "addTrack()")}} has been updated to create a transceiver as required.</li>
- <li>Support for <a href="/en-US/docs/Web/API/WebVTT_API">WebVTT</a> regions was implemented in Firefox 58 but disabled by default. They're now available by default ({{bug(1415805)}}).</li>
- <li>Firefox now supports WebVTT <code>REGION</code> definition blocks whose settings list has one setting per line instead of all of the settings being on the same line of the WebVTT file ({{bug(1415821)}}.</li>

- <li>The <code>SAMEORIGIN</code> directive of the {{httpheader("X-Frame-Options")}} header has been changed so that it checks not only the top-level IFrame is in the same origin, but all its ancestors as well ({{bug(725490)}}).</li>
- <li>Image resources loaded from different origins to the current document are no longer able to trigger HTTP authentication dialogs ({{bug(1423146)}}).

- <li>HTTP authentication now uses <code>utf-8</code> encoding for usernames and passwords (rather than <code>ISO-8859-1</code>) for parity with other browsers, and to avoid potential problems as described in {{bug(1419658)}}.</li>
- <li>Everyday the <a href="https://searchfox.org/mozilla-central/source/security/manager/ssl/nsSTSPreloadList.inc">HSTS preload list</a> is updated from Google. Normally this doesn't warrant a note, but in this release new TLDs were included, notably <code>.app</code> and <code>.dev</code>. While they are new TLDs developers might have used them for local development and be surprised by this change. Note that <a href="https://tools.ietf.org/html/rfc2606">reserved TLDs</a> should be used for local development instead.</li>

-
-<p><a href="https://hacks.mozilla.org/2017/08/inside-a-super-fast-css-engine-quantum-css-aka-stylo/">Firefox's new parallel CSS engine</a> — also known as <strong>Quantum CSS</strong> or <strong>Stylo</strong> — which was <a href="/en-US/Firefox/Releases/57#Firefox_57_Firefox_Quantum">first enabled by default in Firefox 57 for desktop</a>, has now been enabled in Firefox for Android.</p>

-<h3 id="Developer_tools">Developer tools</h3>
-
-<ul>
- <li>In the CSS Pane rules view (see <a href="/en-US/docs/Tools/Page_Inspector/How_to/Examine_and_edit_CSS">Examine and edit CSS</a>), the keyboard shortcuts for precise value increments (increase/decrease by 0.1) have changed from <kbd>Alt</kbd> + <kbd>Up</kbd>/<kbd>Down</kbd> to <kbd>Ctrl</kbd> + <kbd>Up</kbd>/<kbd>Down</kbd> on Linux and Windows, to avoid clashes with default OS-level shortcuts (see {{bug("1413314")}}).</li>
- <li>Also in the CSS Pane rules view, <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_variables">CSS variable names</a> will now auto-complete ({{bug(1422635)}}). If you enter <code>var(</code> into a property value and then type a dash (<code>-</code>), any variables you have declared in your CSS will then appear in an autocomplete list.</li>
- <li>In <a href="/en-US/docs/Tools/Responsive_Design_Mode">Responsive Design Mode</a>, a <em>Reload when...</em> dropdown has been added to allow users to enable/disable automatic page reloads when touch simulation is toggled, or simulated user agent is changed. See <a href="/en-US/docs/Tools/Responsive_Design_Mode#Controlling_page_reload_behavior">Controlling page reload behavior</a> for more details ({{bug(1428816)}}).</li>
- <li>The <code>view_source.tab</code> preference has been removed so you can no longer toggle <a href="/en-US/docs/Tools/View_source">View Source</a> mode between appearing in a new tab or new window. Page sources will always appear in new tabs from now on ({{bug(1418403)}}).</li>
-</ul>
-
-<h3 id="HTML">HTML</h3>
-
-<p>Pressing the Enter key in <code>designMode</code> and <code>contenteditable</code> now inserts <code>&lt;div&gt;</code> elements when the caret is in an inline element or text node which is a child of a block level editing host — instead of inserting <code>&lt;br&gt;</code> elements like it used to. If you want to use the old behavior on your app, you can do it with <code>document.execCommand()</code>. See <a href="/en-US/docs/Web/Guide/HTML/Editable_content#Differences_in_markup_generation">Differences in markup generation</a> for more details (also see {{bug(1430551)}}).</p>
-
-<h3 id="CSS">CSS</h3>

-<ul>
- <li>The {{cssxref("align-content")}}, {{cssxref("align-items")}}, {{cssxref("align-self")}}, {{cssxref("justify-content")}}, and {{cssxref("place-content")}} property values have been updated as per the latest <a href="https://drafts.csswg.org/css-align-3/">CSS Box Alignment Module Level 3</a> spec ({{bug(1430817)}}).</li>
- <li>The {{cssxref("paint-order")}} property has been implemented ({{bug(1426146)}}).</li>

- </li>
- <li>The {{jsxref("Array.prototype.values()")}} method has been added again ({{bug(1420101)}}). It was disabled due to <a href="https://www.fxsitecompat.com/en-CA/docs/2016/array-prototype-values-breaks-some-legacy-apps/">compatibilty issues</a> in earlier versions.

-<h4 id="New_APIs">New APIs</h4>
-
-<ul>
- <li>The <a href="/en-US/docs/Web/API/Web_Authentication_API">Web Authentication API</a> has been enabled ({{bug(1432542)}}).</li>
- <li>The <a href="/en-US/docs/Web/API/WebVR_API">WebVR API</a> has been enabled by default on macOS ({{bug(1438044)}}).</li>

-<h4 id="DOM">DOM</h4>
-
-<ul>
- <li>In the <a href="/en-US/docs/Web/API/Web_Authentication_API">Web Authentication API</a>, the <code>MakePublicKeyCredentialOptions</code> dictionary object has been renamed {{domxref("PublicKeyCredentialCreationOptions")}}; this change has been made in Firefox ({{bug(1436473)}}).</li>
- <li>The <code>dom.workers.enabled</code> pref has been removed, meaning workers can no longer be disabled ({{bug(1434934)}}).</li>
- <li>The {{domxref("Document.body","body")}} property is now implemented on the {{domxref("Document")}} interface, rather than the {{domxref("HTMLDocument")}} interface ({{bug(1276438)}}).</li>
- <li>{{domxref("PerformanceResourceTiming")}} is now available in workers ({{bug(1425458)}}).</li>
- <li>The {{domxref("PerformanceObserver.takeRecords()")}} method has been implemented ({{bug(1436692)}}).</li>
- <li>The {{domxref("KeyboardEvent.keyCode")}} attribute of punctuation key becomes non-zero even if the active keyboard layout doesn't produce ASCII characters. See <a href="/en-US/docs/Web/API/KeyboardEvent/keyCode#keyCode_of_punctuation_keys_on_some_keyboard_layout">these notes for more detail</a>. Please do <strong>not</strong> use <code>KeyboardEvent.keyCode</code> in new applications — use {{domxref("KeyboardEvent.key")}} or {{domxref("KeyboardEvent.code")}} instead.</li>
- <li>The {{domxref("Animation.updatePlaybackRate()")}} method has been implemented ({{bug("1436659")}}).</li>
- <li>New rules have been included for determining <a href="/en-US/docs/Web/API/KeyboardEvent/keyCode#keyCode_of_punctuation_keys_on_some_keyboard_layout">keyCode values of punctuation keys</a> ({{bug(1036008)}}).</li>

-
-<ul>
- <li>When recording or sharing media obtained using {{domxref("MediaDevices.getUserMedia", "getUserMedia()")}}, muting the camera by setting the corresponding track's {{domxref("MediaStreamTrack.enabled")}} property to <code>false</code> now turns off the camera's "in use" indicator light, to help the user more easily see that the camera is not in use ({{bug(1299515)}}). See {{SectionOnPage("/en-US/docs/Web/API/MediaDevices/getUserMedia", "User privacy")}} for more details.</li>
- <li>Removing a track from an {{domxref("RTCPeerConnection")}} using {{domxref("RTCPeerConnection.removeTrack", "removeTrack()")}} no longer removes the track's {{domxref("RTCRtpSender")}} from the peer connection's list of senders as reported by {{domxref("RTCPeerConnection.getSenders", "getSenders()")}} ({{bug(1290949)}}).</li>
- <li>The {{domxref("RTCRtpContributingSource")}} and {{domxref("RTCRtpSynchronizationSource")}} objects' timestamps were previously being reported based on values returned by {{jsxref("Date.getTime()")}}. In Firefox 60, these have been fixed to correctly use the <a href="/en-US/docs/Web/API/Performance_API">Performance Timing API</a> instead ({{bug(1433576)}}).</li>
- <li>As per spec, the {{domxref("ConvolverNode.ConvolverNode","ConvolverNode()")}} constructor now throws a <code>NotSupportedError</code> if the referenced {{domxref("AudioBuffer")}} does not have 1, 2, or 4 channels ({{bug(1443228)}}).</li>
- <li>The obsolete {{domxref("RTCPeerConnection")}} event handler {{domxref("RTCPeerConnection.onremovestream")}} has been removed; by now you should be using {{event("removetrack")}} events instead ({{bug(1442385)}}).</li>
- <li>The primary name for {{domxref("RTCDataChannel")}} is now in fact <code>RTCDataChannel</code>, instead of being an alias for <code>DataChannel</code>. The name <code>DataChannel</code> is no longer supported ({{bug(1173851)}}).</li>

- <li>The {{domxref("Window.event")}} and {{domxref("Event.returnValue")}} properties — originally proprietary IE features, then also supported across other browsers for compatibility purposes — have been re-introduced in Firefox 66, after first being added in versions 63 and 64 respectively but then removed again due to compatibility issues. </li>
- <li>From 66 onwards, when the {{domxref("KeyboardEvent.keyCode")}} property of the {{event("keypress")}} event object is 0, the value will be the same as {{domxref("KeyboardEvent.charCode")}}. Conversely, when <code>charCode</code> is 0, it will be the same as <code>keyCode</code>. This mirroring behavior matches other browsers and is expected to solve most associated compatibility issues, however user agent sniffing might cause further issues in some JavaScript libraries. Note that in spec terms, we've switched from the <em>split model</em> to the <em>conflated model</em> (see <a href="https://w3c.github.io/uievents/#determine-keypress-keyCode">How to determine keyCode for keypress events</a> in the UI Event spec).</li>

- <li>The {{domxref("MediaDevices")}} method {{domxref("MediaDevices.getDisplayMedia", "getDisplayMedia()")}}, available as <code>navigator.mediaDevices.getDisplayMedia()</code>, has been added and synchronized with the specification. This method lets you capture a screen or part of a screen as a {{domxref("MediaStream")}} for manipulation or sharing ({{bug(1321221)}}).</li>
- <li>As a step toward eventually deprecating the Firefox-specific {{domxref("MediaDevices.getUserMedia", "getUserMedia()")}}-based method for capturing screen and window contents, the non-standard <code>mediaSource</code> constraint now treats the values <code>screen</code> and <code>window</code> identically. Both now present a list of both screens and windows for the user to choose from ({{bug(1474376)}}).</li>
- <li>{{domxref("RTCRtpStreamStats.qpSum", "qpSum")}} has been added to local outbound {{domxref("RTCRTPStreamStats")}} objects. This measures the total of the Quantization Parameter values for every frame sent or received on the video track. The higher this number, the more compressed the stream probably is ({{bug(1347070)}}).</li>
- <li>In a step along the road toward implementing support for Feature Policy in a future Firefox update, {{domxref("MediaDevices.getUserMedia", "getUserMedia()")}} can no longer be used in situations in which there is no proper origin for the content, such as when called from a sandboxed {{HTMLElement("iframe")}} or from a <code>data</code> URL entered into the address bar by the user.
