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.
