Want to help document Firefox OS 1.0.1? Check out the list of B2G-related bugs that need to be written about and pitch in!

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

<iframe>has been implemented and it's prefixed predecessor

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)

- 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.
