YouTube and AdBlockers

It has reached my ears that obviously some people seem to have problems with YouTube while using AdBlockers. The thing is, I didn't think it was a thing because I have never stumbled into the problem because I watch YouTube all the time and I use AdBlockers and it just hasn't happened to me that anything wouldn't play. I did get a message once but everything still worked, so I shrugged and went on watching videos.

Now I wonder why and if this could help someone.

I am using Firefox because it is one of the few browsers that hasn't integrated allowing spying on me into their main mission.

I also use AdBlock Plus (ABP) in combination with AdBlock Ultimate (and NoScript, but that is a bit too much work for the average user and it doesn't interfere with YouTube when I turned it off to test this). So it seems, these two Add-Ons on Firefox mean there is no issue and I still watch everything without Ads these days.

If anyone who has trouble using YouTube ad-free wants to try it and tell me about it, I am curious.
