DNI_R Is Privacy Badger useful if i already use ublock origin in medium mode and cookie autodelete?
uBlock origin works white/black lists while Privacy Badger uses an algorithm to dynamically detect some behaviors so they are complementary.
Regarding Cookie Autodelete, I use it because blocking all 3rd party cookies can be problematic and also because it allows me to easily whitelist some cookies directly from the toolbar of my browser.
