User Agent

- -

The Gecko part of the user agent string changed. The build date (which hadn't been updated since 2010) was removed, and the Gecko version number was put in its place instead. So Gecko/20100101 -> Gecko/17.0. This may affect you if you are doing user agent sniffing.

{{ draft() }}

Firefox 23 Aurora (pre-Beta) was released on . While it has been developed to maintain compatibility as much as possible, the new version includes some changes affecting backward compatibility aimed at improving interoperability with the other browsers or following the latest Web standards. Here's the list of such changes — Hope this helps whenever you test your sites or applications.

-

This article only explains the changes that may affect backward compatibility for Websites. For the other new features and changes, please read the following documents:

- -

This list may be updated until the release of the final version on , so please check back later.

-
-

CSS

-
-

能产生文字闪烁效果的text-decoration:blink属性值被删除

- -

Firefox previously supported the Netscape-derived blink effect with the blink keyword for the CSS text-decoration property as well as the HTML blink element and the DOM String.blink method. Starting with Firefox 23, the blink effect no longer works. While text-decoration:blink continues to be supported by the CSS parser and the DOM APIs, the HTML parser has dropped the blink element support, thus the element will be treated as an unknown element. Internet Explorer, Chrome and Safari haven't supported the effect. Opera may also drop the support once it switches to the Blink rendering engine.

-
-
-
-

DOM

-
-

添加到侧边栏的功能被删除

- -

window.sidebar.addPanel and window.sidebar.addPersistentPanel are no longer supported. These methods were a part of a Netscape-derived API which allowed Web publishers to integrate their contents as sidebar panels of the browser. They were not standardized, rarely used, and not very well supported. No other browsers have implemented these.

-

There is also a plan to remove window.sidebar itself in the future.

-
-
-

requestAnimationFrame脱前缀

- -

requestAnimationFrame, the unprefixed version of mozRequestAnimationFrame, has been added. This unprefixed method passes a DOMHighResTimeStamp to callbacks. It has microsecond precision and can be compared to performance.now().

-

On the other hand, the prefixed method, which will be removed in the future, continues to pass an epoch-based DOMTimeStamp to callbacks. The passed-in value has millisecond precision and can be compared to mozAnimationStartTime.

-
-
-

跨域文档的contentDocument属性现在返回null

- -

The contentDocument property on frames now returns null if the caller doesn't subsume the document. This change affects the contentDocument property on the frame, iframe and object elements as well as the getSVGDocument method on the embed, iframe and object elements.

-
-
-

window.defaultStatus被删除

- -

The window.defaultStatus property is no longer available. Setting this property has had no effect in Firefox because the default preference has disallowed changes to the status text by Web pages. Recently, the Firefox UI dropped support for enabling that pref. Also, this property is not specified in the HTML5 spec. window.status is still available.

-
-
-

不再允许创建AnimationEvent和TransitionEvent

- -

The support for obsolete document.createEvent("AnimationEvent"), document.createEvent("TransitionEvent"), AnimationEvent.initAnimationEvent, and TransitionEvent.initTransitionEvent has been removed.

-
-
-
-

视频和音频

-
-

Audio Data API被废弃

- -

The non-standard, experimental Audio Data API is now considered deprecated. The standard Web Audio API can be used instead.

-
-
-

HTMLMediaElement.initialTime被删除

- -

The HTMLMediaElement.initialTime property is no longer available, due to the removal from the spec.

-
-
-
-

安全和隐私

-
-

在SSL页面(HTTPS)上的非SSL活动内容会被默认阻止

- -

Firefox 18 introduced preferences to block loading content from non-SSL (http) sites on SSL (https) pages. One of those preferences, security.mixed_content.block_active_content is now enabled by default in order to enhance user security. That means insecure scripts, stylesheets, plug-in contents, inline frames, Web fonts and WebSockets are blocked on secure pages, and a notification is displayed instead. It will not block "display content" like images, videos or audio. See Tanvi Vyas' blog post for details.

-

Mozilla is tracking mixed content issues found on major sites as well as its own properties.

Search plugins

Starting in Firefox 45, search plugins located in the user's profile's searchpluginsdirectory are no longer automatically loaded on startup. Instead, a list of user-installed plugins is maintained and only those plugins are loaded. In effect, this means that the only ways to install new search plugins are for the user to do so in the Firefox UX (via OpenSearch discovery, for instance) or for an add-on to install it. Also, when a new search plugin is installed, more information is recorded about where it came from, for future use by profile debugging and cleaning tools.

This behavior, controlled by the preference browser.safebrowsing.blockedURIs.enabled, helps to improve the performance of sites and Firefox in general without having significant impact on site usability. It also helps improve stability of the browsing experience by elminating a major cause of crashes. The blocked Flash modules include several used just for fingerprinting purposes, as well as a number of "supercookie" modules, and in the future may be expanded to include more types of blocked modules. See {{bug(1275591)}} for details.

This marks the next step in the journey toward a plugin-free future. HTML is very close to the point where plugins will no longer be needed to get the job done.

针对网页开发者们的若干改变

- -

开发者工具

- -
    -
  • 在CSS格检查器中显示以负号开始的行号({{bug(1369942)}}).
    • -
- -

HTML

- -
    -
  • 在打标签的窗体控件中采用labels 属性，比如 {{domxref("HTMLInputElement.labels")}} ({{bug(556743)}}).
    • -
  • 实现了 <link rel="preload">; 更详细的内容，可以参见 Preloading content with rel="preload"  ({{bug(1222633)}}). 需要注意的是，当前的Firefox只支持对可缓存的资源进行预加载。
    • -
- -

CSS

- -
    -
  • 实现了Mozilla自有的属性 {{cssxref("<color>")}} 值为 -moz-win-accentcolor 以及 -moz-win-accentcolortext (可以参见 {{bug(1344910)}}), 以及专用的媒体查询语句 -moz-windows-accent-color-in-titlebar (参见{{bug(1379938)}}).
    • -
- -

SVG

- -

无修改.

- -

JavaScript

- -
    -
  • The Intl API has been enabled on Firefox for Android ({{bug(1344625)}}).
    • -
- -

APIs

- -

New APIs

- -

No changes.

- -

DOM

- -
    -
  • On Mac, {{domxref("Document.hidden")}} is now true when the window is behind another non-translucent application {{bug(1236512)}}.
    • -
  • The {{domxref("Gamepad.displayId")}} property has been implemented ({{bug(1375816)}}).
    • -
  • The {{domxref("PerformanceTiming.secureConnectionStart")}} property has been implemented ({{bug(772589)}}).
    • -
  • Firefox used to accept iso-2022-jp-2 sequences silently when an iso-2022-jp {{domxref("TextDecoder.TextDecoder","TextDecoder()")}} was instantiated, however this has now been removed to simplify the API, as no other browsers support it and no pages seem to use it. ({{bug(715833)}}).
    • -
  • The 4ms clamping behaviour of {{domxref("WindowOrWorkerGlobalScope.setTimeout","setTimeout()")}} and {{domxref("WindowOrWorkerGlobalScope.setInterval","setInterval()")}} has been updated to be more in line with other browsers, as described in Timeouts throttled to >=4ms ({{bug(1378586)}}).
    • -
  • The Page Visibility API's {{domxref("Document.onvisibilitychange")}} handler has been added ({{bug("1333912")}}).
    • -
  • The {{domxref("Window.showModalDialog()")}} method has been removed ({{bug(981796)}}).
    • -
- -

DOM events

- -
    -
  • {{domxref("GlobalEventHandlers.onwheel")}} is now available on {{domxref("HTMLElement")}} — it wasn't before ({{bug(1370550)}}).
    • -
- -

WebRTC

- -
    -
  • Firefox now supports the {{domxref("RTCPeerConnection")}} properties which let you examine the current and pending configurations of the local and remote ends of the connection, to help manage changes in configuration: {{domxref("RTCPeerConnection.currentLocalDescription", "currentLocalDescription")}}, {{domxref("RTCPeerConnection.pendingLocalDescription", "pendingLocalDescription")}}, {{domxref("RTCPeerConnection.currentRemoteDescription", "currentRemoteDescription")}}, and {{domxref("RTCPeerConnection.pendingRemoteDescription", "pendingRemoteDescription")}}.
    • -
- -

Canvas and WebGL

- -
    -
  • The {{domxref("CanvasRenderingContext2D.drawImage()")}} method has been updated so that smoothing occurs when downscaling even if imageSmoothingEnabled is false. This is not mandatory as per spec, but follows Chrome's behaviour. See {{bug(1360415)}}.
    • -
  • An {{domxref("SVGImageElement")}} can now be used as a {{domxref("CanvasImageSource")}}, e.g. as the image source in a {{domxref("CanvasRenderingContext2D.drawImage","drawImage()")}} call ({{bug(1382027)}}).
    • -
- -

Security

- -

No changes.

- -

Plugins

- -

No changes.

- -

Other

- -
    -
  • Gecko now encodes URLs internally as punycode, to avoid URL encoding problems (see {{bug("945240")}}, also see discussion in {{bug("942074")}}).
    • -
  • Firefox on Windows and Mac OS X can now be made to run in headless mode using the -headless flag (see {{bug(1355150)}} and {{bug(1355147)}}).
    • -
- -

Removals from the web platform

- -

HTML

- -
    -
  • The {{htmlelement("isindex")}} element has been removed from the HTML parser, and from form submission ({{bug(1266495)}}).
    • -
  • The {{htmlelement("applet")}} element has been removed ({{bug(1279218)}}).

    This article provides information about the changes in Firefox 68 that will affect developers. Firefox 68 was released on July 9, 2019.
    
-
-
    Changes for web developers
    
-
-
    Developer tools
    
-
-
    Browser/web console
    
-
-
      
- 
    • The Web console now shows more information about CSS warnings, including a node list of the DOM elements that used the rule ({{bug(1093953)}}).
      • 
- 
    • You can now filter content in the Web console using regular expressions ({{bug(1441079)}}).
      • 
- 
    • The Browser console now allows you to show or hide messages from the content process by setting or clearing the checkbox labeled Show Content Messages ({{bug(1260877)}}).
      • 
-
    
-
-
    JavaScript debugger
    
-
-
      
- 
    • You can now Search in all files in the current project from the debugger by pressing Shift + Ctrl + F (Windows or Linux) or Shift + Cmd + F (macOS) ({{bug(1320325)}}).
      • 
-
    
-
-
    Network monitor
    
-
-
      
- 
    • The Network monitor request list now allows you to block a specific URL ({{bug(1151368)}}).
      • 
- 
    • You can now resend a network request without editing the method, URL, parameters, and headers, using the Resend command on the context menu ({{bug(1422014)}}).
      • 
- 
    • The context menu of the Network monitor Headers tab now allows you to copy all or some of the header information to the clipboard in JSON format ({{bug(1442249)}}).
      • 
-
    
-
-
    Page inspector
    
-
-
      
- 
    • A button has been added to the rules panel of the Page inspector that allows you to toggle the display of any print media queries ({{bug(1534984)}}).
      • 
- 
    • The fonts panel now includes a slider to modify letter-spacing ({{bug(1536237)}}).
      • 
- 
    • A warning icon appears next to unsupported CSS properties or rules that have invalid values, to help you understand why certain styles are not being applied ({{bug(1306054)}}).
      • 
-
    
-
-
    Storage inspector
    
-
-
-
-
    Other
    
-
-
      
- 
    • The Accessibility Inspector now includes a new Check for issues feature, which will include a number of audit tools to highlight accessibility problems on your web pages. The first available check is contrast, for highlighting color contrast problems.
      • 
- 
    • The preference that controls the visibility of internal extensions (system add-ons and hidden extensions) on the about:debugging page has been changed from devtools.aboutdebugging.showSystemAddons to devtools.aboutdebugging.showHiddenAddons ({{bug(1544372)}}).
      • 
- 
    • Responsive design mode has been redesigned — the Device Settings dialog (device selection menu > Edit List...) is now more intuitive and simpler to use ({{bug(1487857)}}).
      • 
-
    
-
-
    Removals
    
-
-
      
- 
    • The "Enable add-on debugging" checkbox has been removed from the about:debugging page ({{bug(1544813)}}).
      • 
-
    
-
-
    HTML
    
-
-
      
- 
    • The {{HTMLElement("track")}} element — represented by {{domxref("HTMLTrackElement")}} — now receives a {{domxref("HTMLTrackElement.cuechange_event", "cuechange")}} event in addition to the {{domxref("TextTrack")}} itself, if the text track is a contained by a media element ({{bug(1548731)}}).
      • 
- 
    • {{htmlelement("link")}} elements support the disabled attribute again, albeit with different behavior. When disabled is set on a <link> element along with rel="stylesheet", the referenced stylesheet is not loaded during page load, and will be loaded on demand when the disabled attribute is changed to false or removed ({{bug(1281135)}}).
      • 
-
    
-
-
     Removals
    
-
-
-
-
    CSS
    
-
-
      
- 
    • CSS Scroll Snapping has been updated to the latest version of the specification ({{bug(1312163)}}) and ({{bug(1544136)}}), this includes:
-
-  
        
-   
      • The scroll-padding properties ({{bug(1373832)}})
        • 
-   
      • The scroll-margin properties ({{bug(1373833)}})
        • 
-   
      • {{CSSxRef("scroll-snap-align")}} ({{bug(1373835)}})
        • 
-  
      
- 
      • 
- 
    • The {{CSSxRef("-webkit-line-clamp")}} property has been implemented for compatibility with other browsers ({{bug(866102)}}).
      • 
- 
    • Support has been added for the {{CSSxRef("::marker")}} pseudo-element ({{bug(205202)}}) and animation for ::marker pseudos ({{bug(1538618)}})
      • 
- 
    • We changed {{CSSxRef("currentColor")}} to be a computed value (except for the {{cssxref("color")}} property)  ({{bug(760345)}}).
      • 
- 
    • Support has been fixed for the ch length unit so it now matches the spec (fallback for no '0' glyph, vertical metrics) ({{bug(282126)}})
      • 
- 
    • The  {{CSSxRef("counter-set")}} property has been implemented. ({{bug(1518201)}}).
      • 
- 
    • We now implement list numbering using a built-in "list-item" counter; this fixes list numbering bugs ({{bug(288704)}}).
      • 
- 
    • Selector matching and parsing support has been implemented for ::part() ({{bug(1545430)}}) and ({{bug(1545425)}}).
      • 
- 
    • CSS Transforms are now supported in indirectly rendered things e.g.)  {{SVGElement("mask")}},  {{SVGElement("marker")}},  {{SVGElement("pattern")}},  {{SVGElement("clipPath")}} ({{bug(1323962)}}).
      • 
- 
    • 
-  
      While we're keeping the prefixed versions of the various gradient properties ({{cssxref("linear-gradient")}}, {{cssxref("radial-gradient")}}, and {{cssxref("repeating-radial-gradient")}} available for compatibility reasons, we have revised how they're parsed so that they're handled much more like the non-prefixed versions. This means that certain existing styles won't work correctly.
      
-
-  
      In particular, the complicated syntax taking both an angle and a position will no longer work, and the to keyword in the <side-or-corner> parameter is not required for the prefixed gradient properties. You are encouraged to use the standard, non-prefixed gradient properties instead, as they're now widely supported ({{bug(1547939)}}).

    • {{CSSxRef("scroll-snap-coordinate")}}, {{CSSxRef("scroll-snap-destination")}}, {{CSSxRef("scroll-snap-type-x")}} and {{CSSxRef("scroll-snap-type-y")}} have been removed.
      • 
- 
    • The {{CSSxRef("scroll-snap-type")}} property has become a longhand, so the old shorthand syntax like scroll-snap-type:mandatory will stop working. See the Firefox Site Compatability note.

    • The legacy {{domxref("CSSStyleSheet.rules", "rules")}} property and {{domxref("CSSStyleSheet.addRule", "addRule()")}} and {{domxref("CSSStyleSheet.removeRule", "removeRule()")}} methods have been added to the {{domxref("CSSStyleSheet")}} interface. These were introduced by Internet Explorer 9 and have never managed to quite be stamped out, so they have been added to improve compatibility with the small percentage of sites that still use them ({{bug(1545823)}}).

    DOM
    
-
-
      
- 
    • The Visual Viewport API has now been enabled by default on Android ({{bug(1512813)}}). Adding this API to desktop versions of Firefox is being tracked in {{bug(1551302)}}.
      • 
- 
    • The {{domxref("Window")}} feature noreferrer is now supported; if specified, the new window's content is loaded without sharing the hostname, IP address, URL, or other identifying information about the host device ({{bug(1527287)}}).
      • 
- 
    • The {{domxref("HTMLImageElement.decode", "decode()")}} method on HTMLImageElement is now implemented. This can be used to trigger loading and decoding of an image prior to adding it to the DOM ({{bug(1501794)}}).
      • 
- 
    • {{domxref("XMLHttpRequest")}} has been updated to no longer accept the non-standard moz-chunked-arraybuffer value for {{domxref("XMLHttpRequest.responseType", "responseType")}}. Code still using it should be updated to use the Fetch API as a stream ({{bug(1120171)}}).
      • 
- 
    • XMLHttpRequest now outputs a warning to console if you perform a synchronous request while handling an {{domxref("Window.unload_event", "unload")}}, {{domxref("Window.beforeunload_event", "beforeunload")}}, or {{domxref("Window.pagehide_event", "pagehide")}} event ({{bug(980902)}}).
      • 
- 
    • The {{domxref("Document.cookie", "cookie")}} property has moved from the {{domxref("HTMLDocument")}} interface to the {{domxref("Document")}} interface, allowing documents other than {{Glossary("HTML")}} to use cookies ({{bug(144795)}}).
      • 
- 
    • The {{domxref("HTMLElement.focus()")}} and {{domxref("SVGElement.focus()")}} methods now accept an optional object that may contain a boolean preventScroll option specifying whether or not to block the browser from scrolling the newly-focused element into view ({{bug(1374045)}}).

    DOM events
    
-
-
      
- 
    • Firefox for Android no longer incorrectly sends a {{domxref("Window.resize_event", "resize")}} event until after the first frame is painted; this improves web compatibility with sites that don't expect this event to occur ({{bug(1528052)}}).
      • 
- 
    • The dispatching of events for non-primary mouse buttons has been made to more closely follow the specification; the {{domxref("Element.click_event", "click")}} event is no longer sent when non-primary buttons are clicked, instead using {{domxref("Element.auxclick_event", "auxclick")}}. In addition, {{domxref("Element.dblclick_event", "dblclick")}} no longer fires for non-primary buttons ({{bug(1379466)}}).
      • 
- 
    • The proprietary {{domxref("MouseEvent.mozPressure")}} property has been deprecated, and will now trigger a warning in the console ({{bug(1165211)}}).

    Media, Web Audio, and WebRTC
    
-
-
      
- 
    • Due to changes in the Google Play store's policies, starting with Firefox 68 for Android, the OpenH264 codec used to handle AVC/H.264 video in WebRTC connections can no longer be downloaded and installed. Therefore, fresh installs of Firefox on Android devices no longer support AVC in WebRTC calls. If you upgrade from earlier versions of Firefox and already have the codec downloaded, it will continue to work. This does not affect other platforms. For more details, see this article on SUMO or {{bug(1548679)}}.
      • 
- 
    • WebRTC has been updated to recognize that a null candidate passed into the {{domxref("RTCPeerConnection.icecandidate", "icecandidate")}} event handler, indicating the receipt of a candidate, instead indicates that there are no further candidates coming; when this happens the ICE gathering ({{domxref("RTCPeerConnection.iceGatheringState", "iceGatheringState")}}) state reaches complete ({{bug(1318167)}}).
      • 
- 
    • The {{domxref("RTCRtpReceiver")}} methods {{domxref("RTCRtpReceiver.getContributingSources", "getContributingSources()")}} and {{domxref("RTCRtpReceiver.getSynchronizationSources", "getSynchronizationSources()")}} now support video tracks; previously they only worked on audio ({{bug(1534466)}}).
      • 
- 
    • The Web Audio API {{domxref("MediaStreamTrackAudioSourceNode")}} interface is now supported, as is the method {{domxref("AudioContext.createMediaStreamTrackSource()")}} ({{bug(1324548)}}).
      • 
- 
    • {{domxref("RTCDataChannel.negotiated")}} is now implemented ({{bug(1529695)}}).
      • 
- 
    • The {{domxref("MediaStreamAudioSourceNode.MediaStreamAudioSourceNode", "MediaStreamAudioSourceNode()")}} constructor has been updated to match the current specification's definition that the "first audio track" in the stream is the track whose ID comes first in lexicographical order ({{bug(1324548)}}).
      • 
- 
    • 
-  
      {{domxref("MediaDevices.getUserMedia", "getUserMedia()")}} may no longer be used from a non-secure context; attempting to do so now throws a NotAllowedError exception. Secure contexts are those loaded using HTTPS, those located using the file:/// scheme, and those loaded from localhost. For now, if you must, you can re-enable the ability to perform insecure calls to getUserMedia() by setting the preference media.getusermedia.insecure.enabled to true ({{bug(1335740)}}).
      
-
-  
      
-  
      Note: In the future, Firefox will also remove the {{domxref("navigator.mediaDevices")}} property on insecure contexts, preventing all access to the {{domxref("MediaDevices")}} APIs. This is already the case in Nightly builds.

      •

    HTTP
    
-
-
      
- 
    • The HTTP {{HTTPHeader("Clear-Site-Data")}} header no longer supports the executionContexts directive. This was removed due to problems with interactions between interconnections among different kinds of data at different points in the navigation process and the way the specification is designed. It has been proposed that this directive be removed from the specification for this reason, among others ({{bug(1548034)}}).

    • The The proxy.register() and proxy.unregister() functions have been deprecated and will be removed from Firefox 71 ({{bug(1545811)}}).
      • 
- 
    • A boolean flag, incognito, has been added to the proxy.RequestDetails. object. When true, it indicates that this was a private browsing request ({{bug(1545163)}}).
      • 
- 
    • The webRequest.RequestFilter parameters can include an incognito parameter. If provided, requests that do not match the incognito state (true or false) will be filtered out ({{bug(1548177)}}).
      • 
- 
    • A string value, cookieStoreId, representing the cookie store ID of the current context, has been added to the proxy.RequestDetails. object ({{bug(1545420)}}).
      • 
- 
    • When an add-on attempts to add a bookmark folder to the root folder, the resulting error message is now much more intuitive ({{bug(1512171)}}).
      • 
- 
    • The promise returned by browser.tabs.duplicate() now resolves immediately, before the tabs are completely loaded ({{bug(1394376)}}).
      • 
- 
    • Support has been added for chrome.storage.managed, allowing web extension settings to be implemented via enterprise policy ({{bug(1230802)}}).
