I’ve been using Firefox since…forever. This is the best browser on earth. The first time I heard Firefox 3.1 beta 2 had been released, I immediately downloaded it and installed it on my computer. There’s lots of significant improvement compared to the old version.

• it’s been released in 54 different languages
• using a new private browsing mode which allows you to browse without leaving traces of where you’ve been
• a new function to remove history in an instant
• new support for worker threads
• supports for new tracemonkey javascript engine
• Improvements to the Gecko layout engine, including speculative parsing for faster content rendering
• removes the new tab switching and preview behavior
• Supports for new web technologies such as the <video> and <audio> elements, the W3C Geolocation API, JavaScript query selectors, CSS 2.1 and 3 properties, SVG transforms and offline applications. (source:Mozilla)

Although there’s lots of improvement, especially on speed, Firefox 3.1b2 lacks of supportive add-ons. When I upgraded my Firefox from 2.0 to 3.1b2, I lost most of my add-ons because of their incompatibility. Anyway, Firefox is still the best for me. You can download 3.1b2 version here.

have fun using the new Firefox.
