So it's that time again... Rated 3 out of 5 stars
Doesn't work at all because YouTube fucked up again (see description of the addon). Hence three stars which I'll revise after it works again.ATM, I've deactivated the addon until there's a working version (current v.1.0.3 doesn't).
@Anysia (see 3d post above): Agreed, but maybe the author should also write an answer to a post now and then. The remark about YT having fucked up again is not really prominent and thus prone to be missed.
