I don't have a problem with unobtrusive adverts and why shouldn't websites try to make money from it's users? (someone's gotta pay for the servers!)
But what I really find annoying are the adverts popping up in YouTube video's which I find distracting as hell.
My question is this, how do I block those sorts of ad's without blocking non-obtrusive everyday adverts?
I'm on a Mac (Leopard) using Firefox.
