Changes for Web developersDeveloper Tools

Highlights:

All devtools bugs fixed between Firefox 36 and Firefox 37.

CSS

display:contents is now activated by default (bug 1102374 and bug 1105369).
CSS multi-column layout is now working on element with display:table-caption (bug 1109571).
Relative positioning (position:relative) of table cells has been implemented (bug 35168).
Our experimental, preffed off by default, implementation of CSS Ruby, now supports vertical positioning using ruby-position (bug 1055665).

HTML

The value <a rel="noreferrer"> now also works when the link is opened in new tab (<a class="external external-icon" href="https://bugzilla.mozilla.org/show_bug.cgi?id=1031264" title="FIXED: does not work if open in new tab">bug 1031264).
The '.' followed by the extension is now allowed in <input accept>: when used, a file selector filters with this given extension to be proposed to the user (<a class="external external-icon" href="https://bugzilla.mozilla.org/show_bug.cgi?id=826176" title="FIXED: File extension support for">bug 826176).

JavaScript

The Map, Set, WeakMap and WeakSet constructors now ignore null iterable (bug 1092538).
The Map, Set, WeakMap and WeakSet constructors now supports monkey-patched prototype.set or prototype.add (bug 804279).
The Non-standard String.prototype.quote() method has been removed (bug 1103181).
The RegExp.prototype.flags property has been implemented (bug 1108467).
Several Array methods have been implemented for typed arrays as well:

The every() and some() methods (bug 1116390).
The find() and findIndex() methods (bug 1078975).
The fill() method (bug 1113722).

The configurable attribute of the Function.length property is now true per the ES6 specification (bug 911142).
The development of ParallelJS (PJS) has been discontinued due to the limited future prospects, little attention and code complexity. The experimental implementation that had been enabled only on the Nightly channel, including the Array.prototype.mapPar, filterPar and reducePar methods, has been completely removed.
