Customize YouTube to work exactly the way you want it to.
I'm using this all the time myself. There is no login to YouTube required and it supports adding subscriptions and doing everything important you can do on YouTube.
Yeah I've removed it already and know all the antics YouTube has been doing as I use Smarttube on my Firetv.
But yeah not very impressed with Freetube in comparison to even a browser and the more I read about it not being able to view age restricted and other content it's not for me especially with the constant freezes.
