Adblock slows Youtube loading

Recently i couldn't understand why Youtube videos loaded slowly using Firefox. I had Adblock plus installed through extensions.
So i un-installed Adblock Plus and installed uBlock Origin instead..
Youtube videos load up almost instantly now and keeps those pesty website advertising pop ups away as well.

you can hit the adblock icon on top right of browser and say disable on this site. adblock plus does a lot better than Ublock in a lot of areas, but UBlock is rare so not attacked as hard on some sites.

I tried to disable adblock on youtube and videos do load normally, but i get that 'You can skip this ad in 5 seconds'

oh please I hate those
