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……
· Per-compartment garbage collection is now enabled, reducing work done during complex animations
great stuff, 对了不知道为啥，一看到compartment我就想到了我们的蜗居… 不是应该是apartment的吗？
· Additional polish for the Firefox Add-ons Manager
嗯，这个学chrome已经学的灰常像了.
· Improved web typography using OpenType with support for ligatures, kerning and font variants
嗯，等我有空先去试试 web fonts 再说吧.
· Web developers can animate content using CSS Transitions
终于支持了，great stuff.
· Responsiveness and scrolling improvements from the new retained layers layout system
没怎么看懂，不过大致能够理解，什么不理解？那就空间想象一下…… 对了，读书时一直听数学老师说男同学一般比较擅长空间想象……
· HTML5 Forms API makes web based forms easier to implement and validate
记得以前看到 sunng提到过 那会只有opera 11完整支持 html5 form，now comes ff4, great stuff!
· Support for the new proposed Audio Data API
nice, 有空一定要try一下.
· Support for HSTS security protocol allowing sites to insist that they only be loaded over SSL
以后就多了一种强制https的办法了，且可能更可靠高效.
· A new feature called Panorama gives users a visual overview of all open tabs, allowing them to be sorted and grouped
应该就是传说中的tab group吧，我昨天不知道怎么整出来过一次，现在找了半天也找不到打开的方法… 放弃…… 休息，不行了，要昏倒了…… To be continued…
