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.

<ol>element is now supported (bug 601912).

<link>element is now supported (bug 786564).
allowfullscreenattribute of the
<iframe>has been implemented and it's prefixed predecessor
mozallowfullscreenis now deprecated.
min-heightnow uses the
autokeyword as initial value (This has an effect only on flex items as it resolves to
0, the previous initial value, for other items). (bug 763689)
- The cascade has been updated: now author
!importantrules override CSS animations. (bug 783714)

truefor h.264 video, whereas in actual fact h.264 is not supported.
- 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 from
contains()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.
Firefox OS specific:

this.doneis undefined (see bug 902565). This is fixed in Firefox 1.2. The referenced bug discusses possible compatibility checks/workarounds for this issue.
