If you are sick of the tracking, invasive fingerprinting and zombie cookies of proprietary video hosting services, there is a Free Software way to avoid most of it: videodownloader
This Free Software uses youtube-dl as a backend and has a nice client front end so you just keep the client on your desktop and then paste in any video link you would like to keep and view later (or right away!) and save it to your storage drive. You can then watch the video offline, and share it easily with friends if you like.
You need git and npm installed already to have the installation work smoothly. If you try it and like it, please let everyone know, as it will encourage others to try.
