Firefox 3.5 was released today. Firefox 3.5  is based on the Gecko 1.9.1 rendering platform, which has been under development for the past year. Firefox 3.5 offers many changes over the previous version, supporting new web technologies, improving performance and ease of use.

Some of the noteable features are:

• Support for the HTML5 <video> and <audio> elements including native support for Ogg Theora encoded video and Vorbis encoded audio. (Try it here!)
• Improved tools for controlling your private data, including a Private Browsing Mode.
• The ability to share your location with websites using Location Aware Browsing. (Try it here!)
• Support for native JSON, and web worker threads.
• Support for new web technologies such as: downloadable fonts, CSS media queries, new transformations and properties, JavaScript query selectors, HTML5 local storage and offline application storage, <canvas> text, ICC profiles, and SVG transforms.

I have been running the beta version of Firefox 3.5 for some time now and have been very impressed to date, especialy performance wise. So if you’re a Firefox fanboi go ahead and download the Firefox 3.5 now. Download available here or locally here.
