@maltepruser whether it's on or off it's useless especially when using YouTube...because you will be defenceless and you will be invaded with a lot of shitty ads in YT
Ghostery till now is the only extension that does the job perfectly (even uBlock origin was useless against the new algorithm of YT that forces us to watch them shitty ads)
So make sure that Ghostery is always on ... That's the most important thing IMHO
