Can´t blocking URLs
I work for a ISP company currently I trying block URLs with a firewall, however for any reason I can´t block URLs when using Mozilla, I tried another explorers like Internet Explorer and these works. I read about DoH but I dont sure that be my issue, I believe that is a issue about Mozilla proxies or something like that.
Any that can read for fix this issue?
