Personally I use Ghostery on Chrome right now but with this development by Mozilla, I'm inclined to switch. Feels good to use a browser with no corporate interests, and a simple feature to stop abuse of cookies by ~70% is just crazy. Too crazy to not be a built-in browser feature. Maybe I'm disrupting how news sites intend to work, but they're disrupting how the web was intended to work.
Anyway, ... I got sidetracked. I meant to say that what's even "funnier" is that if I disable Ghostery for some domain temporarily, the number of trackers usually skyrocket even further, since now the scripts get to run more scripts.
Yep, i have noticed those "matryoshka" scripts from time to time. Enabling one script domain in Noscript result in 2+ more waiting to be enabled after page reload.
And sometimes you have to dig 3+ layers into the nesting to get the site to function at all...
Sometimes the number of domains that gets loaded in the background on certain sites is mind numbing.
