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."
