    EcmaScript 6 (Harmony) implementation continues!

    • New mathematical methods have been implemented on Math: Math.fround() (バグ 900125).
    • The method Array.of() is now implemented on Array (バグ 866849).
    • The methods Number.parseInt() and Number.parseFloat() have been implemented (バグ 886949)
    • The methods Map.prototype.forEach() and Set.prototype.forEach() are now implemented (バグ 866847)
    • New mathematical methods have been implemented on Math: Math.log10(), Math.log2(), Math.log1p(), Math.expm1(), Math.cosh(), Math.sinh(), Math.tanh(), Math.acosh(), Math.asinh(), Math.atanh(), Math.trunc(), Math.sign() and Math.cbrt() (バグ 717379).
    • Support for binary and octal integer literals has been added: 0b10101010, 0B1010, 0o777, 0O237 are now valid (バグ 894026).
    • The machine epsilon constant, that is the smallest representible number that added to 1 will not be 1, is now available as Number.EPSILON (バグ 885798).
    • Arrow functions are no longer automatically in strict mode unless explicitly requested with "use strict" (バグ 852762)).
    • The String.prototype.repeat JS method has been implemented (バグ 815431).
    • The Object.defineProperty method can now be used to redefine the length property of an Array object.
    • The option to disable JavaScript, including the options to allow moving windows/replace context menu, have been removed. You may still disable JavaScript by double clicking the "javascript.enabled" option in about:config.
    • Asm.js optimizations are enabled, making it possible to compile C/C++ applications to a subset of Javascript for better performance.

    • Web apps using draggable text with Kinetic 3.x are working, even when using the Cairo canvas backend (バグ 835064).
    • The for each…in statement has been deprecated and should not be used. Consider using the new for…of statement (バグ 804834).
    • Support for the Map.prototype.keys, Map.prototype.values, and Map.prototype.entries has been added (バグ 817368).
    • Map and Set objects have changed from having a size() method to a size property (バグ 807001).

    DOM/API

    Firefox OS-specific:

    • Device Storage API: When getting a cursor callback from navigator.getDeviceStorage("sdcard").enumerate, this.done was undefined in Firefox <1.2 (see バグ 902565). This is now fixed. The referenced bug discusses possible compatibility checks/workarounds for this issue.
    • The RTCPeerConnection Interface from WebRTC is implemented, but currently disabled by default in B2G, as it is not yet functional on Firefox OS devices (see バグ 942343.)
    • Web notifications are supported in Firefox 1.2, therefore the Notification object should be used in preference to the old deprecated mozNotification object (see バグ 899574 .)
    • mozInputMethod has been added to allow for people to write 3rd party keyboards. See the test application in gaia/test_apps for a reference implementation.
    • The Media Recording API has been implemented (see バグ 803414, バグ 889720)
    • KeyboardEvent.repeat now supported (バグ 600117)
    • 3rd party keyboards now supported (バグ 816869)
    New WebGL 1 extensions supported in Firefox OS 1.2:
    Note: availability of these extensions depends on device capabilities; not all extensions will be available on all devices.

    General Gecko:

    SVG

    General Gecko:

    MathML

    General Gecko:

    • The dir attribute for controlling directionality of formulas on e.g. <math> or <mrow> elements is now equivalent to using the direction CSS property.
    • The equal sign ("=") is now stretchable.
    • The "updiagonalarrow" value for the notation attribute on <menclose> elements has been added.
    • Negative widths for the <mspace> element has been implemented (バグ 717546).
    • The <semantics> element now determines the visible child as described in the MathML3 specification.
    • To help MathML authors debugging "invalid-markup" errors in their documents, MathML parsing errors (such as having too many / too few child elements) and warnings about deprecated attributes or wrong attribute values are now reported to the Error Console.
    • The scriptminsize attribute now accepts unitless values and percent values. They are interpreted as multiples of the default value ("8pt").
    • Unitless values are now also allowed for the mathsize and fontsize attributes; they multiply the default value.

    ネットワーク

    General Gecko:

    • We continue to update our CSP implementation to match the CSP 1.0 spec, which reached Candidate Recommendation:
      • Support for the spec-compliant Content-Security-Policy HTTP header (in addition to the experimental X-Content-Security-Policy) has been added (バグ 783049). Note: the patch for this new header landed in Firefox 21, it is disabled on builds (バグ 842657).

    Worker

    General Gecko:

    セキュリティ

    General Gecko:

    • Mixed content blocking. Firefox will no longer load non-secure (http) resources on secure (https) pages (バグ 834836).
    • The standard syntax of CSP 1.0 policies are now implemented and enforced by default.

    XForms

    General Gecko:

    Support for XForms has been removed in Firefox 19.
