If you have Firefox or Chrome installed, you can download Adblock Plus for free (just search it). I use Adblock Plus and have never had to watch a video ad on Youtube.
Yes it does.
No, YouTube is international.
you can't your blocked
it's not blocked
no they can not(:
Go to google then write youtube downloader click on the third option and down load youtube.(The most simple way of opening youtube when it is blocked... Simple)
If YouTube is blocked, then you may use YouTube on your mobile phone or the YouTube Kids App. Some schools and parents may block the main YouTube website due to potentially offensive content.
I would recommend installing adblock, yes.
AdBlock - Chrome - was created on 2009-12-08.
it can either be a bad video and youtube has blocked it(meaning taken it out)
Got to settings>general>restrictions then unlock YouTube! :)
