Detach Video is a free application that`s very useful, and works to watch any video shown by your browser, in a separate window. This is very comfortable because only this video appears in the window.
Detach Video requires no installation: just double click on it so it places itself in the system tray, next to the clock. Later, right clicking on the program icon accesses the configuration options. It includes a shortcut (F12) which you can change for another. Its effectiveness is shown with, for example, YouTube. If you open any video from this popular website and press F12, you can watch it in an independent window.
If you often watch videos on the Internet, it is worth doing so with Detach Video.
