我们已经向您介绍了Firefox下一个主要版本3.0的第一个beta版，今天Mozilla发布了beta 2供愿意的测试人员和不耐烦的“福克斯用户”下载。第二个测试版会堵塞内存泄漏（yippee！）并添加了新的URL自动完成显示、智能书签文件夹和改进的下载管理器等功能。跳转后获得更多关于beta 2 Goods的详细信息。

发行说明中值得注意的beta 2改进包括：

• Location bar & auto-complete: type in all or part of the title, tag or address of a page to see a list of matches from your history and bookmarks; a new display makes it easier to scan through the matching results and find that page you're looking for.
• Smart Bookmarks Folder: quickly access your recently bookmarked and tagged pages, as well as your more frequently visited pages with the new **art bookmarks folder on your bookmark toolbar.
• New Download Manager: the revised download manager makes it much easier to locate downloaded files, and displays where a file came from.
• Memory usage: Over 300 individual memory leaks have been plugged, and a new XPCOM cycle collector completely eliminates many more. Developers are continuing to work on optimizing memory use (by releasing cached objects more quickly) and reducing fragmentation. Beta 2 includes over 30 more memory leak fixes, and 11 improvements to our memory footprint.

当然，这是一个测试版，所以除非你对一些不稳定和不兼容的扩展保持冷静，而纠结得到解决，否则你不想全职使用它。Firefox3 Beta 2是所有平台的免费下载。
