    Firefox OS 1.2 is at a pre-release stage right now. Its Gecko component is based on Firefox 26 (encompassing all Gecko additions between Firefox 19 and Firefox 26; see Firefox 26 release notes for developers for the latest.) This page details the developer features newly implemented in Firefox OS 1.2.

    Developer Tools


    General Gecko:

    • The srcdoc attribute of <iframe>, allowing the inline specification of the content of an <iframe>, is now supported (bug 802895).
    • When used with a "image/jpeg" type, the method HTMLCanvasElement.toBlob now accepts a third attribute defining the quality of the image (bug 891884).
    • The <track> element has been implemented behind the media.webvtt.enabled property (bug 833385).
    • The <blink> element support is now completely dropped. The <blink> tag now implements the HTMLUnknownElement interface (bug 857820).
    • The range state of the <input> element (<input type="range">) has been switched on by default (bug 841950).
    • The HTML5 <data> element has been implemented (bug 839371).
    • The HTML5 <time> element has been implemented (bug 629801).
    • The range state of the <input> element (<input type="range">) has been implemented, behind the preference dom.experimental_forms_range, only enabled by default on Nightly and Aurora channel (bug 841948).
    • The support for the <template> element, part of the Web component specification has been implemented (bug 818976).
    • The scoped attribute has been added to the <style> element. It allows to include styles that are isolated from the rest of the document. Such styles can be selected using the :scope CSS pseudo-element introduced in Firefox 20. (bug 508725).
    • The new HTML <main> element has been implemented (bug 820508).
    • Support for the download attribute on the <a> and <area> element has been added (bug 676619).

    • The methods Number.parseInt() and Number.parseFloat() have been implemented (bug 886949)
    • The methods Map.prototype.forEach() and Set.prototype.forEach() are now implemented (bug 866847)

    • Support for binary and octal integer literals has been added: 0b10101010, 0B1010, 0o777, 0O237 are now valid (bug 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 (bug 885798).
    • Arrow functions are no longer automatically in strict mode unless explicitly requested with "use strict" (bug 852762)).

    • 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.
    • ES6 Arrow Function syntax has been implemented (bug 846406).
    • The new function has been added (bug 839979).

    • Web apps using draggable text with Kinetic 3.x are working, even when using the Cairo canvas backend (bug 835064).
    • The for each…in statement has been deprecated and should not be used. Consider using the new for…of statement (bug 804834).

    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 bug 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 bug 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 bug 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 bug 803414, bug 889720)
    • KeyboardEvent.repeat now supported (bug 600117)
    • 3rd party keyboards now supported (bug 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:

    • 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 (bug 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.


    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 (bug 783049). Note: the patch for this new header landed in Firefox 21, it is disabled on builds (bug 842657).


    General Gecko:


    General Gecko:

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


    General Gecko:

    Support for XForms has been removed in Firefox 19.
