I tried alpha version in Opera Developer and I am not impressed at all.
Privacy Badger uses ABP code and only blocks 3rd party tracking similar to built in Tracking Protection in IE11.
It looks like it is blocking some stuff that ABP is not blocking (Google things),but those are whitelisted in EasyList
and EasyPrivacy filter lists because otherwise some elements on websites are broken.
Maybe in the future I'll try Privacy Badger again.
