Firefox 9.0发布

On 2011年12月20日, in soft, by netoearth

Firefox 9发布。不同于以往大同小异的快速发布版本,新版本有一项重要变化:JavaScript引擎启用了类型推断(Type Inference),这一变动让JS执行速度提高了20-30%。类型推断令JavaScript在速度和优化上接近编译语言C 或C++。Firefox的JaegerMonkey现在与Chrome的V8站在了同一起跑线,在某些情况下甚至还占据了领先位置。如果你因为JS性能而改用Chrome,也许可以再回去体验一下Firefox了。Firefox 9的其它小变动还包括,改进HTML5、MathML和CSS标准支持,支持字体伸展,改进文本溢出(text overflow)支持,修正稳定性问题。

  • Added Type Inference, significantly improving JavaScript performance
  • Improved theme integration for Mac OS X Lion
  • Added two finger swipe navigation for Mac OS X Lion
  • Added support for querying Do Not Track status via JavaScript
  • Added support for font-stretch
  • Improved support for text-overflow
  • Improved standards support for HTML5, MathML, and CSS
  • Fixed several stability issues
