Thanks a lot for helping me. I tried UnPlug on YouTube and it worked! But
maybe i should have been more specific. I only browse with Tor (i'll try I2P
and others later) and don't know if UnPlug or ViewTube can compromise things:

specifically topics:
a)
b)
d) Although this one is more about "documents", maybe it's safer to open the
videos on a disconnected computer independently of their format, as a rule of
thumb.
Anyway, i'm not going to keep the files that have copyright issues. I would
love to watch them on the fly online. Unfortunately YouTube and other
websites mistreat their users.
I will as much as i can download free formats instead of patent-encumbered
ones.
But all of this, only if the downloading proves to be anonymous.
