Firefox 3, in Beta 3 just hit the mainstream. Developers fixed over 300 memory leaks and reduced the software’s already lean memory footprint. Hmmm… hard to imagine optimizing something already kickass!

The shortlist of new features and changes in this milestone include:

* Enhanced security
* Enhanced ease of use
* Optimal personalization
* Enhanced platform features
* Performance maximization

Sadly, beta software is not meant for the general public but hey- if you’re the experimental  then it is available for download.

The more complete list of new features and changes in this milestone include:

* Improved security features such as: better presentation of website identity and security including support for Extended Validation (EV) SSL certificates, malware protection, stricter SSL error pages, anti-virus integration in the download manager.
* Improved ease of use through: easier add-on discovery and installation, improved download manager search and progress indication in the status bar, resumable downloading, full page zoom, and better integration with Windows Vista, Mac OS X and Linux.
* Richer personalization through: one-click bookmarking, smart bookmark folders, location bar that uses an algorithm based on site visit recency and frequency (called “frecency”) to provide better matches against your history and bookmarks for URLs and page titles
* Improved platform features such as: new graphics and font rendering architecture, JavaScript 1.8, major changes to the HTML rendering engine to provide better CSS, float-, and table layout support, native web page form controls, colour profile management, and offline application support.
* Performance improvements such as: better data reliability for user profiles, architectural improvements to speed up page rendering, over 350 memory leak fixes, a new XPCOM cycle collector to reduce entire classes of leaks, and reductions in the memory footprint.
