Easy YouTube Video Downloader
Streaming video can't work without an active Internet connection--no Net equals no Flash video, so sites such as YouTube are off-limits. Easy YouTube Video Downloader to the rescue: This extension allows you to download Flash movies from YouTube and other sites for later viewing with or without your connection. In addition to all the free clips, you can find free versions of full movies such as Ghostbusters on YouTube.
