Firefox 3.5, codenamed Shiretoko, is a major development milestone in Mozilla Firefox web browser development, where developers decided to skip Firefox 3.1 Moniker (Firefox 3.1 Beta 3 been changed to Firefox 3.5 Beta 4 directly). After 4 betas and 3 release candidates (RC), Firefox 3.5 has been finalized.

Firefox 3.5 includes the following new features:

  • Firefox now available in more than 70 languages.
  • Improved tools for controlling your private data, including a Private Browsing Mode.
  • Better performance and stability with the new TraceMonkey JavaScript engine.
  • The ability to provide Location Aware Browsing using web standards for geolocation.
  • Support for native JSON, and web worker threads.
  • Improvements to the Gecko layout engine, including speculative parsing for faster content rendering.
  • Support for new web technologies such as: HTML5 <video> and <audio> elements, downloadable fonts and other new CSS properties, JavaScript query selectors, HTML5 offline data storage for applications, and SVG transforms.
