Firefox 3 Beta is Available for Download

Mozilla Developers Center has announced last month that Firefox 3 Beta is now available for download.

New features and changes in this milestone that require feedback include:

• Improved security features such as: protection from cross-site JSON data leaks, tighter restrictions on site-specific content using effective TLD service, better presentation of website identity and security, malware protection, stricter SSL error pages, anti-virus integration in the download manager, version checking for insecure plugins.
• Improved ease of use through: better password management, easier add-on installation, new download manager with resumable downloading, full page zoom, animated tab strip, and better integration with Windows Vista, Mac OS X and Linux.
• Richer personalization through: one-click bookmarking, smart bookmark folders, location bar that matches against your history and bookmarks for URLs and page titles, ability to register web applications as protocol handlers, and better customization of download actions for file types.
• 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 330 memory leak fixes, a new XPCOM cycle collector to reduce entire classes of leaks, and reductions in the memory footprint.

(You can find out more about all of these features in the “What’s New” section of the release notes.)
