First seen in 2010, Utilities. This page records what the extension did, whether it is still available, and what to use instead.
What it was
Chrome YouTube Downloader added a Download button under YouTube videos and saved them as FLV, MP4 (including 720p and 1080p) or MP3. It was one of the most downloaded early Chrome extensions, with more than 850,000 downloads by 2012, distributed outside the Chrome Web Store because Google never allowed YouTube downloaders there.
No longer available
Extensions that download YouTube videos or audio are prohibited by the Chrome Web Store's developer policies, so this extension was never carried by the store and is not distributed here. Downloading YouTube content is also against YouTube's terms of service. The list below shows the video downloaders the store does permit; they work on sites other than YouTube.
