Firefox ony: We've all come across a video or flash game we'd like to save for posterity or at least for future goofing off. Web Video Downloader makes it easy to snag video and games off the web.
Web Video Downloader adds a small icon to your menu bar, as seen in the screenshot, which becomes animated when there is available content on the page you are on. With the extension you can download FLV, SWG, WMV, AVI, MOV, RM, and RMVB, among others.
All the downloads are handled by a download manager, a basic two column affair that shows which files are pending and which are downloaded. Once you've downloaded the source file you move or rename it from within the download manager.
If you have a favoured tool for grabbing video from the web, Firefox-based or otherwise, let's hear about it in the comments. Web Video Downloader requires Firefox and is available for Windows and Mac.
