great same as ghostery but this is more complex and better

Never had a problem with it. GOOD ONE.

The best adblock extension out there.

For the concerns about the hostname and ip permission, see https://github.com/gorhill/uBlock/wiki/Permissions#access-ip-address-and-hostname-information . The permission ONLY means that the addon can make DNS queries, while it still has NO ACCESS to your computer's IP adress. Furthermore, it doesn't have a central server and has no intension to "mine" your data.

I've been using UBlock Origin for about a year and it's so great that I've registered my Firefox account specifically so as to give them a 5-star rating amidst all the fake hysteria about the permissions the new CNAME unmasking functionality needs.
