「ChromeとAndroidを統合することはない」とGoogleのシュミット会長
「ChromeとAndroidを統合することはない」──。米Googleのエリック・シュミット会長が3月21日（現地時間）、インドのニューデリーで同社が開催したIT活用に関するカンファレンス「Big Tent Activate Summit New Delhi 2013」でそう語った。 英Guardianのアラン・ラスブリッジャー記者とのセッションの最後のQ＆Aで、「Googleには2つのモバイルOS、ChromeとAndroidがありますが、これを統合する予定はありますか？」という質問に対し「ノーというのが答えだ」とはっきり否定し、2つはまったく異なる目的のために存在するものだからだと説明した。 Googleは先日、Androidの責任者であるアンディ・ルービン上級副社長が退任し、Google Chrome他を担当する上級副社長、スンダル・ピチャイ氏がAndroidも統括すると発表した。
asm.js: closing the gap between JavaScript and native

The conclusion mentions LLJS as another asm.js source language. asm.js defines a subset of JavaScript that can be compiled to fast executables. It has been created at Mozilla by David Herman, Luke Wagner and Alon Zakai. According to the specification, “[asm.js] effective

Badass JavaScriptA showcase of awesome JavaScript that pushes the boundaries of what's possible on the web, by @devongovett. David Herman, Luke Wagner, and Alon Zakai (also the developer of Emscripten) of Mozilla have been working on the asm.js spec, which aims to be a subset of the JavaScript language that can be highly optimized after you have opted in. It is designed mostly for compilers like
asm.js in Firefox Nightly | Luke Wagner's Blog
I’m happy to announce that OdinMonkey, an asm.js optimization module for Firefox’s JavaScript engine, is now in Nightly builds and will ship with Firefox 22 in June. What is asm.js? Why are we doing it, and how are we getting to within 2x of native performance? This post won’t be able to go into too much detail since we’re hard at work preparing for Mozilla’s upcoming GDC session, which you should

Firefox Developer Tools work week wrap-up – Mozilla Hacks - the Web developer blog
Last week in Sunnyvale we had the first Developer Tools work week to include the recently-integrated Jetpack team ( for a slightly different take on the week, see Paul’s post. ). And what a week! I was a bit shocked by how many things I thought were just interesting ideas suddenly became real things that actually worked. By Friday morning we had some amazing demos from the team, which I will try t

771331 - Password manager would really like to know when <input type=password> is added to the DOM
The Firefox password manager is currently pretty basic -- it watches for documents being loaded (via @mozilla.org/docloaderservice;1), waits for DOMContentLoaded to fire, and then attempts to fill in passwords on the page. This has a couple of significant problems: * Bad for performance. The vast majority of pages being loaded don't need the password manager to be doing anything. But it has no way
