Smaller Memory Footprint
Short and sweet, Firefox uses less of your computer’s memory while it’s running.

Memory Management
With a new management function in place, Firefox keeps memory usage under control. The XPCOM cycle collector continuously cleans up unused memory. Plus, hundreds of memory leaks have been remedied.

Faster Page Load
A redesigned page rendering and layout engine means you see Web pages faster—and in the way they were meant to be seen.

Color Profile Support
The colors in your online photo albums will be sharper and more brilliant than ever, thanks to improvements to our graphics engine.

Super Speed
Firefox 3.5 includes the TraceMonkey JavaScript engine, which gives the browser dramatically better performance than ever before. Firefox has always been fast, but this is the fastest Firefox ever (more than twice as fast as Firefox 3, and ten times as fast as Firefox 2), meaning Web applications like email, photo sites, online word processors and more will feel snappier and more responsive.

The new version focuses on speed and keeping your data secure and private. New features include:

• Private Browsing Mode, which allows you to browse the Internet without Firefox retaining any of data about which sites and pages you have visited.
• Forget About This Site, which allows you to delete all traces of a specific website from your history.
• Clear Recent History, which allows you to clear all traces of data in your history from the previous hour, two hours, four hours, or everything from that day.
• Recently closed windows, which allows you to re-open a window you may have accidentally closed.

Download It Here

The Mozilla Foundation’s Firefox 3.5 preview version is now available for download and we have had a few hours playing with it.

Firstly it is a bit faster than earlier versions, although all the browsers on the market these days, such as Opera, Chrome and Safari are faster than the earlier generation.

But the new browser has a few things which are more interesting including the use of open-source video standards, geo-location capabilities, and a few nice graphics tricks.

With 3.5 it is possible to run a video player based on the open-source video formats Ogg Vorbis and Theora. What is cool is that by using HTML5 links and other interactive elements can easily be placed inside videos. What is interesting is that it can do things that Flash can’t, and if it is supported by websites it could send Adobe packing.
