Privacy Badger

So i installed a few addons yesterday , Ublock Origin , Cookie autodelete and Privacy badger. I already have 3rd part cookies disabled in the browser (firefox)

Privacy badger has not blocked a single thing since installing , i,m wondering if Ublock is taking care of everything and Privacy Badger is not needed ?

I have done a lot of browsing and it has done literally nothing , not changed any settings since install though

Have i done something wrong or is this normal ?
