What tracker-blocking extention should I use?

I used to use Ghostery but other users told me it’s not safe. Now,privacy badger seems like it’s not protecting me much and I’m not sure if i should set the sliders to red,yellow,or green so I’m kind of confused. Disconnect seems a little complicated – i don’t know if the checkmark means i’m protected or no,there don’t seem to be many options for customization either. What should I use?
