Thanks. Both go exactly in the direction i was thinking. Both appear to look at network traffic, connections to third-party servers.
I will say, lightbeam, at some point, will more or less not work. Especially if you did probably over 200 websites and let it connect everything together. But it is a more pretty and easier way to understand tool.
I've always enjoyed the cover flow of trackers that the duckduckgo extension shows
DDG is the shit, but it can break some website so i won't recommend this to the general public.
