不管您现在使用的是IE浏览器还是火狐2.0或者那些IE内核的浏览器，我都建议您使用火狐浏览器3.0版本，火狐3.0最新Beta版4.0为我们展现了一个最好的浏览器平台，它能使我们能更好的浏览互联网。下面是我列出的换用火狐3.0的五大理由。

1.新的页面信息标签

这是火狐浏览器3.0版的最新特性。

下面是国外网友对它的介绍：
This is the best new feature of Firefox 3, and one of the niftiest browser tools of all time. To get to it, when you're at a site, click the favicon at the left of the Address Bar, and from the pop-up that appears, click More Information. A tabbed dialog box appears, shown below, that lets you get security information about the site, see all the media on the page, get general information, and view and subscribe to any feeds on the page. Best of all, you can customize how you browse the site from now on, including whether to block or open pop-ups, whether to block cookies, load images from the page, and so on. It's the best and most comprehensive way to customize your browsing experience.

2.更强大的下载管理器

相比火狐2.0的下载管理，新的火狐可谓发生了巨变，不过如果您喜欢迅雷之类的第三方下载软件，也可以使用相应扩展如FLASHGOT来完成。

Firefox 3 includes a comprehensive download manager built directly into it --- no more searching in vain through your hard disk for files you downloaded. It keeps a list of all files you downloaded, including from where you downloaded them, and lets you search through it. (See screenshot below.) You can open up not just the file itself, but the folder which contains it. There's a useful status bar for when you're downloading. And it integrates directly with your virus scanner, so that you'll see the virus-scanning take place right within the Download Manager.

3.更小的内存占用

Mozilla claims that it's plugged hundreds of memory leaks, and taken other steps to reduce memory use, including collecting and releasing unused memory, and reducing memory fragmentation. It also says caching strategies have been tuned. I haven't run tests, but I can say that I've been running the browser for well over 24 hours, and it hasn't suffered from memory bloat.

4.更安全

Firefox 3 will warn you when you're visiting a page known to harboar malware, viruses, and Trojans. It also disables old, insecure versions of plug-ins. And the Page Info feature, which I've written about above, gives you security information about the Web site you're visiting.

5.更漂亮的外观

As you can see below, Firefox has entered the modern age, with a chiselled, 3D look -- you won't feel as if you're using a 1999 browser anymore. It will also reflect the personality of whatever operating system you're currently running.
