Flash Video Downloader 2.5 is opera extension or not?:crybaby:

There is an extension called FastestTube - YouTube Video Downloader for opera browser that can be used to download youtube videos directly from the browser itself rather than installing 3rd party software on your computer that is some additional task. The extension adds a simple drop-down below the YouTube videos where you can easily select and download the video in the format of choice. The extension uses code from userscripts.org by Ionut Alex Chitu.
