CSS

• CSS variables have been implemented (Firefox bug 773296). Mozilla Hacks article can be found here. They are enabled by default only for non-release builds (on release builds flip the pref layout.css.variables.enabled to true if you want to play with them).
• Добавлена поддержка visibility: collapse в Flexboxes (Firefox bug 783470).
• Свойство box-sizing больше не нуждается в префиксе (Firefox bug 243412).
• The will-change property, a hint to that something will animate has been added. The preference layout.css.will-change.enabled must be switched to true to enable it. (Firefox bug 940842)
• Scientific exponential notation, like 3e1 or 10e+0, is now supported for <number> values (Firefox bug 964529).
• Тип изображения <gradient> теперь поддерживается в border-image (Firefox bug 709587).
• The touch-action property has been implemented. It is not activated by default; the layout.css.touch_action.enabled pref controls it. (Firefox bug 795567)

HTML

• <input type=color> и <input type=number> доступны по умолчанию.
• Support for the non standard <pre cols> has been removed, as well as the layout effect of <pre wrap> . Both effects can, and should, be achieved using CSS. (Firefox bug 949879)

JavaScript

• Реализованы новые методы строк в ECMAScript 6: String.prototype.codePointAt() и String.prototype.fromCodePoint() (Firefox bug 918879).

• The ECMAScript Internationalization API (ECMA-402) has been implemented and is now enabled by default in Firefox Desktop (Firefox bug 853301):

  • New objects in the new Intl object namespace:

    • Intl.Collator
    • Intl.DateTimeFormat
    • Intl.NumberFormat

  • The following methods of String, Number and Date have been updated to include the locales and options arguments per ECMA-402:

    • String.prototype.localeCompare()
    • Number.prototype.toLocaleString()
    • Date.prototype.toLocaleString()
    • Date.prototype.toLocaleDateString()
    • Date.prototype.toLocaleTimeString()

• To match the updated ECMAScript6 draft specification, the Map and Set objects now treat -0 and +0 as the same when checking for key and value equality.

• Promise has been enabled by default (Firefox bug 918806).

• Completed generators now returns an IteratorResult object instead of throwing (Firefox bug 958951).

• A malformed JSON string parsed by JSON.parse() now yields a more detailed error message containing the line and column number that caused the parsing error. This is useful when debugging large JSON data.

Интерфейс/APIs/DOM

• A new type of workers, SharedWorker, is now available by default (Firefox bug 924089).
• The URLUtils interface now supports the searchParams property returning a URLSearchParams object, allowing to modify the search params of an URL (Firefox bug 887836). The URLSearchParams constructor allows easier parsing of query strings.
• The Worker.onLine property is now supported, allowing to know the online/offline status in workers (Firefox bug 925437).
• As part of the implementation of Web Components, the HTMLShadowElement interface has been implemented behind the dom.webcomponents.enabled. Flip it to true if you want to use it. (Firefox bug 887538).
• The read-only property HTMLIFrameElement.sandbox is no longer a string but an HTMLSettableToken (Firefox bug 845057).
• On HTMLCanvasElement.getContext(), the value moz-webgl is no longer supported. Use the standard webgl value (Firefox bug 913597).
• The constructor for ImageData has been added. This interface can be used in a Worker. (Firefox bug 959958)
• The property location.origin is now available in workers (Firefox bug 964148).
• The ValidityState.badInput property has been implemented (Firefox bug 827161).
• The deprecated Window.pkcs11 property has been removed; it was returning null since Firefox 3.0.14. (Firefox bug 964964)
• The Node.cloneNode() and Document.importNode() methods take the Boolean deep argument. Until now, if omitted, these methods acted as if the value of deep was true. But this behavior has been changed as per the latest spec, and if omitted, the methods will act as if the value was false. (Firefox bug 937461)
• Window._content is no longer available to Web content (Firefox bug 946564).
• URLUtils.port behavior has been slightly changed: set to '' will set it to the default port associated with the protocol, and 0 to 0. (Firefox bug 930450)
• Document.referrer is now based on the incumbent script (Firefox bug 887928).
• Gamepad API включён по умолчанию (Firefox bug 878828).
