Not ignoring you Cheerio, but I loaded the Do Not Track Plus, and it's plonked the thingie where Adblock Plus used to go.
I then loaded (on this newish installation) Adblock in the normal way, but all it offers as a switch is a new bar at the bottom. Grrrrrrrrr indeed. I guard my screen jealously.
I don't mind going to tools to turn it on, but oddly it doesn't even offer a switch there. Any ideas?
