all right, go on. 接上篇和上上篇 . 这俨然已经全然变成了一个体力活…… anyway, let’s finish it.

· An experimental API is included to provide more efficient Javascript animations

看到experimental，然后点进去看到 “We do not guarantee to support it forever, and I wouldn’t evangelize sites to depend on it.” 我就一下子没了兴趣，当然你如果有兴趣完全可以深入研究一番。

· Firefox now supports the HTML5 video “buffered” property

HTML5 video的“buffered”属性，注意打了引号，我起初以为是video标签开始支持buferred这个attribute，但是我特地查看了下 这个demo ，却根本没有发现buffered这个attribute，于是我就开始confuse了，算了还是引用它自己的intro吧，“This is cool because we can now accurately determine which time-segments of a video we can play and seek into without needing to pause playback to download more data.”

· Changes to how XPCOM components are registered in order to help startup time and process separation

No more frozen interfaces!

ok, 继续，接上篇 .

· You can turn any tab into an “App Tab” by right-clicking on it and selecting “Make into App Tab” from the context menu

蛮fancy的应用，fancy就fancy在人家safari，chrome，opera，IE不支持，fancy就fancy在也实用不到哪去，暂且就认为只是为了省空间吧，还只是视觉空间，说不定还多搞你点存储空间复杂度，空间换空间？好的.

· The default homepage design has been refreshed

自从用了 speed dial 之后，我已经不知道 homepage 张啥样好多年……

· Overhaul of the bookmarks and history code, enabling faster bookmarking and startup performance

nice code refactor, 一个字，为了速度，汗，好像是两个字……

标题看起来非常official，实际上就是很official… 因为咱是从mozilla的 official site 拷过来的…… 本来昨天就想拷的，结果事情实在太多，只好拖到现在，虽然有点out了不过也无妨，因为彼时彼刻，恰如此时此刻～

Firefox 4 is based on the Gecko 2.0 Web platform. This release features JavaScript execution speeds up to six times faster than the previous version, new capabilities for Web Developers and Add-on Developers such as hardware accelerated graphics and HTML5 technologies, and a completely revised user interface.

Firefox每次minor版本的更新都伴随着其内核 Gecko版本的更新 ⁱ，这次major版本更新，Gecko也索性来个大版本号，步调要一致，不然要扯着蛋，嗯…
我不知道你，反正我打开FF4的第一反应是快ⁱⁱ，这个跟6倍速 javascript 性能提升不无关系，当然肯定还有UI的优化，不像以前点个按钮给我个圈圈让我等，上了个厕所倒了杯水回来还是那个圈圈在那欢快的转…… 另外硬件加速，html5什么的我们下面应该会有具体细则，这里只是暂行条例，只是个大方向，详细的征收细则还需要之后由地方政府提供.

1. 话说回来，浏览器不更新这个还更新什么 [↩]
2. 注意，不是指初次启动速度，这个貌似还是painfully slow…… [↩]
