FDM lets you download files and whole web sites from any remote server via HTTP, HTTPS and FTP.
You can also download files using BitTorrent protocol.
Flash video download
Download video from video sites, such as Youtube, Google Video, etc. The video can then be saved in native .flv format or converted to one of more popular video formats.

GNU General Public License

A built-in Upload Manager lets you upload your files easily to share them with other people. Upload manager can be easily integrated with your system (Windows Explorer, Internet Explorer, Outlook Express).

Enjoy safer and more rewarding downloading

Biennesoft YouTube Downloader

Biennesoft YouTube Downloader
download and convert videos from YouTube

Biennesoft YouTube Downloader is a simple tool to download video clips from YouTube and convert them to iPod, PSP, Cell Phone, Windows Media, XVid or MP3. The program uses a rudimentary 2-step process that first downloads the video into a generic file (without extension), which you then have to rename, load and convert to the selected video format. The process is far from elegant, but it works. Biennesoft YouTube Downloader uses FFmpeg as engine for the video conversion.

Firefox火狐浏览器

World famous web browser.

• Tab browsing
• Lots of add-ons to make it more powerful
• Different inside engine to decode the HTML gives you a different experience from IExplorer.

据说是很快的网页浏览器。但是声称最快的是Opera，这个以后再说。Firefox出来后最特别的功能就是可以开一个Tab而不是ie那样的一次开一个Windows。当然火狐也不是靠这个才得到众多用户的芳心的。他还有众多的插件。
比如 IETab, 可以用IE的内核来解释HTML，这样就可以不离开火狐就用IE的效果看网页了
比如 Web Developer's Toolbar 是网页开发者的工具条，提供了显示网页结构，过滤图片，过滤CSS效果，等等一大堆功能。
比如View Source Chart用图的形式显示网页源代码，让你对网页的结构有更深层次的了解。
等等。
还等什么，
