I'm currently using the Video Downloader add-on for Firefox to download videos from websites where videos are hosted on. It is working perfectly on those websites but has limitations when it comes to different type of websites that use MMS or RealMedia links for their movies for example. While it works very well on Flash video sites, it does not work on other types of sites.
Unplug steps in providing the technology to discover media links uses by mms and real media videos as well. It is also working for flv files that Flash video sites use but not that comfortable as the video downloader add-on. Once the extension is installed you can use the add-on by selecting Tools / UnPlug to scan the website automatically for media links.
A better option would be to add the unplug icon to one of your toolbars for faster access. To do that right-click a toolbar and select customize from the menu. Scroll down until you see the unplug fish and drag it to the toolbar of your choice.
Most of the time you receive a list of possible media streams that the extension has detected on a page. Not all may work though and it is up to you to find the working one from the selection. Unplug tries to aid you by suggesting one or two of the links that are most likely the ones pointing to the media file. I would use this plugin for the sites that regular Flash downloaders are not able to process at all.
Instead of saving the files, you can also use the information to stream the videos in your preferred media player provided that it supports the streaming of media files of the discovered type.
The Unplug extension has not been updated since 2011, but it is still compatible with the most recent versions of the Firefox web browser.
Update: Unplug has been updated in 2013 again which indicates that the project itself is not dead. It is fully compatible with all recent versions of Firefox.
