New Firefox beta finally arrives

Under development for ten months, Firefox 3.5 Beta 4 is finally available for download.

Based on the Gecko 1.9.1 rendering platform, Firefox 3.5b4 is available in 70 languages and features improved tools for managing private data, including a private – aka porn – mode.

Mozilla claims the new browser offers better performance and stability with the new TraceMonkey JavaScript engine, together with the ability to provide location aware browsing using web standards for geolocation.

Improvements to the Gecko layout engine include speculative parsing for faster rendering. Support for HTML5 video and audio, downloadable fonts and other new CSS properties, JavaScript query selectors, HTML5 offline data storage for applications, and SVG transforms are also included.

The 7.6MB beta is available in Windows, Mac and Linux versions and you can get it from here. The usual dire warnings about compatibility problems with some websites and add-ons apply.
