Firefox OS 1.0.1 was first offered to partners for release on July 2, 2013, and was the first official release of Firefox OS. Its Gecko component is based on Firefox 18 (see Firefox 18 for developers), released on January 18, 2013. For older updates, have a read of the older Firefox desktop release notes, starting with Firefox 17 for developers. This page details the developer features newly implemented in Firefox OS 1.0.1.
HTML
Firefox OS-specific:
<input type="file">
disabled due to memory usage implications (bug 832923).
General Gecko:
- The
reversed
attribute of the<ol>
element is now supported (bug 601912). - The
crossorigin
attribute of the<link>
element is now supported (bug 786564). - The
allowfullscreen
attribute of the<iframe>
has been implemented and it's prefixed predecessormozallowfullscreen
is now deprecated.
CSS
General Gecko:
- The
min-width
andmin-height
now uses theauto
keyword as initial value (This has an effect only on flex items as it resolves to0
, the previous initial value, for other items). (bug 763689) - The cascade has been updated: now author
!important
rules override CSS animations. (bug 783714) - The
background
shorthand property now recognizes CSS3background-size
property specified inside. (bug 570326) - Initial support for the CSS Flexbox Module has been landed. It is disabled by default but can be enabled by setting
layout.css.flexbox.enabled
to true. (bug 666041)
JavaScript
Firefox OS-specific:
- When detecting
<video>
support for different formats,HTMLMediaElement.prototype.canPlayType
incorrectly reportstrue
for h.264 video, whereas in actual fact h.264 is not supported.
General Gecko:
- Harmony's (ECMAScript 6) Direct Proxies have been landed (bug 703537). Warning: the implementation contains a couple of known bugs, missing features and misalignements with the current state of the spec. Do not rely on it for production code.
- The ECMAScript 6
contains()
method is now implemented on strings. This is unfortunately not compatible with Mootools 1.2, which expects different behavior fromcontains()
on strings but does not ensure it. Newer versions of Mootools fix this issue; sites should upgrade their Mootools version to something newer than 1.2.
DOM/API
Firefox OS specific:
- Device Storage API: When getting a cursor callback from
navigator.getDeviceStorage("sdcard").enumerate
,this.done
is undefined (see bug 902565). This is fixed in Firefox 1.2. The referenced bug discusses possible compatibility checks/workarounds for this issue. - Telephony API landed
- Contacts API landed
- Settings API landed
- Geolocation API landed
- Web Activities landed
- TCP Socket landed
- Sensor API landed
- Permissions and Security Model landed
General Gecko:
navigator.mozPay
has been landed (bug 767818).window.devicePixelRatio
has been landed (bug 564815).- The MacOS X backend for
window.navigator.battery
has been implemented (bug 696045). MozBlobBuilder
is removed. Developers need to useBlob
constuctor for creating aBlob
object (bug 744907).- The
visibilitychange
event and the Page Visibility API has been unprefixed (bug 812086). TextDecoder
andTextEncoder
have been added. Note that the implementation and spec of these evolved and have been changed in Firefox 19 (bug 764234).HTMLMediaElement
.src
has been separate in two properties: the standardsrc
property, dealing withDOMString
, and the prefixedmozSrcObject
property, dealing with media streams (bug 792665).- Support for transferable objects.
- The
Screen.lockOrientation()
method now supports anArray
ofDOMString
as argument (bug 784549).
Network
General Gecko:
- Quality factors ("q-values") are now clamped to 2 digits in HTTP
Accept-Language
header (bug 672448). - The
ALLOW-FROM
syntax of theX-FRAME-OPTIONS
HTTP Response header is now supported (bug 690168).
