First seen in 2010, Other. This page records what the extension did, whether it is still available, and what to use instead.
What it was
Easy YouTube Video Downloader offered one click downloads in FLV, 3GP, MP4, 720p and 1080p MP4, and MP3 straight from the YouTube page. It was a port of the popular Firefox add-on of the same name and was distributed outside the Chrome Web Store, which does not accept YouTube downloaders. The Firefox version, Easy Youtube Video Downloader Express, is still published on Mozilla Add-ons.
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.
