Yeah signed in on Firefox (No VPN needed), it doesn't seem to work with adblock plus or anything like that, the one (I think) that works the best is uBlock Origin extension
Ok nice one I'll have a look at that.
From what I remember, if I'm logged into Google Chrome, but NOT logged into YouTube (ie; no account) then I *think* that I don't see ads - it's when you are logged into YouTube with a YouTube account that it insists that you adhere to their terms and conditions and demands you switch your ad-blocked off.
Just been playing with it - with no YouTube account and Ghostery is blocking all ads.
