My favourite unexpected bonus from switching to Linux has been a completely as free youtube experience. Not entirely sure why this magic is happening but I love it.
On windows Firefox + ublock origin is an ad free experience for YouTube. Any chance you picked a browser that has ublock origin added hy default?

Hmmm, I could’ve sworn my Firefox had ublock origin on windows but I might’ve screwed something up etc.

I’m not one to look a gift horse in the mouth though!
