所有平台：Mozilla刚刚发布了Firefox 3的最新版本Beta 3。Firefox 3的内存问题比其前身要少，但最重要的扩展可能尚未与之兼容，它面向愿意生活在边缘的测试人员和早期采用者(更新：以下是如何在不干扰当前安装的情况下测试Firefox 3，以及如何强制您的扩展在Firefox 3 Beta版中工作。）我们之前发布的Firefox 3 Beta 1屏幕截图教程不包括Beta 3的更改，但这篇对Beta 3的深入评论展示了Firefox 3的最新外观、按钮、对话框和功能。更新：这里是对Beta 2改进的总结：

• One-click site info: Click the site favicon in the location bar to see who owns the site and to check if your connection is protected from eavesdropping. Identity verification is prominently displayed and easier to understand. When a site uses Extended Validation (EV) SSL certificates, the site favicon button will turn green and show the name of the company you're connected to.
• Malware Protection: malware protection warns users when they arrive at sites which are known to install viruses, spyware, trojans or other malware.
• New Download Manager: the revised download manager makes it much easier to locate downloaded files, and you can see and search on the name of the website where a file came from. Your active downloads and time remaining are always shown in the status bar as your files download.
• Podcasts and Videocasts can be associated with your media playback tools.
• Integration with the Mac: the new Firefox theme makes toolbars, ic***, and other user interface elements look like a native OS X application. Firefox also uses OS X widgets and spell-checker in web forms and supports Growl for notificati*** of completed downloads and available updates.
• Integration with Linux: Firefox's default ic***, butt***, and menu styles now use the native GTK theme.
• Star button: quickly add bookmarks from the location bar with a single click; a second click lets you file and tag them.
• 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. New in Beta 3 is an improved search algorithm which calculates the recency and frequency of a visit to come up with a frecency score that is used to determine the most relevant results.
• Download & Install Add-***: the Add-*** Manager (Tools > Add-***) can now be used to download and install a Firefox customization from the thousands of Add-*** available from our community add-*** website. When you first open the Add-*** Manager, a list of recommended Add-*** is shown.
• Speed: Major architectural changes (such as the move to Cairo and a rewrite to how reflowing a page layout works) put foundati*** in place for major performance tuning which have resulted in speed increases that continue to increase page drawing speed in Beta 3. This release also features over 90 changes that improve performance over the previous beta.
• Memory usage: Over 350 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 3 includes more than 50 improvements to memory use over the previous beta.

我们想要明天的最终版本。Firefox3Beta3是所有平台的免费下载。
