There's a ton of great content on YouTube and other video Web sites, but if you're not connected to the Internet, it's inaccessible. Sothink Web Video Downloader for Firefox is a browser extension that makes it easy to download a wide variety of different types of videos so that you can view them no matter where you are.
The add-on installs easily and appears as an icon to the left of Firefox's address bar. The icon is grayed out when Sothink Web Video Downloader doesn't detect a downloadable video, but it becomes colored and animated when it does. Downloading a video is as easy as clicking the button, selecting the destination location, and clicking OK. The extension then opens a new Web page that shows a progress bar depicting how much of the file has been downloaded. We downloaded several videos in different formats and didn't encounter problems with any of them. Although the FLV format, which is found on YouTube and other Flash-based video sites, is probably the most common format that users will encounter, the extension can also handle MOV, AVI, WMV, and a few other file types. Sothink Web Video Downloader also comes with an optional FLV player, a nice touch since most media players can't play FLV files. Overall, Sothink Web Video Downloader for Firefox didn't do anything that we haven't seen many times from other browser extensions and applications, but it works just fine for what it is.
Sothink Web Video Downloader for Firefox installs and uninstalls without issues. We recommend this extension to all users.
