Did and extensive testing of uBlock after the new permissions. I also compared with the previous version. The conclusion: Previous versions of uBlock did NOT track your IP and/or device. This new version that request new permissions, DO use your host name and access your IP.

There has been a lot of speculations about this recently. I have no idea what happened with uBlock, so I choose not to go into that. I can, however, confirm that there is data mining going on with this version. What happens with the user information (IP address, Host information / Name and Device information) I have no way to know from the tests.

Realmente eficaz, el problema viene cuando los sites que visitas bloquean el contenido al ver que UBO está instalado en el navegador.

"Important: the statement "IP address" refers to the IP address of the servers to which your browser connects, NOT your specific IP address. uBO has no access to (and no need to know) your specific IP address."

the best adblock ever

Blocks lots of things, configurable (maybe too much :p), very rewarding. The recent downvotes about additional permissions to acces IP and hostname are just bad wording on the Firefox permission popup, and there's already a Firefox bug open about this, see https://github.com/gorhill/uBlock/wiki/Permissions#access-ip-address-and-hostname-information . So plese stop downvoting this excellent softawre for no real reason.

ZoomerBoomer: "Originally this review was one star after getting the "Access IP address and hostname information" notice with the latest update. However, I was not fully informed of what this meant nor educated on how the WebExtension JavaScript API is laid out.

According to the developer and my own research, uBlock Origin has no access to YOUR IP address. The extension is asking for permission to access the IP address of the website/server you are trying to connect to. The reason why you may have seen or may now see the "Access IP address and hostname information" notice is because, IRONICALLY, uBlock Origin required more information from the servers being accessed in order to block trackers which had found a technique to bypass the filters/rules that uBlock uses. In order to do so, this was only possible by allowing the extension to access server-side DNS information, which is what triggered the "Access IP address and hostname information" notice.

So, be rest assured that this extension has not sold itself to the devil! We still have a reliable extension being developed by those with our best intentions in mind.
