Then all works correct. The "prefered language" which you chose in Firefox is for the websites, not for Firefox directly (menu, buttons, and so on). Firefox (and Ubuntu) should be in Italien, when you install the package "language-pack-it".

And that's in your case English. -- Website is not shown in the correct language https://bugs.launchpad.net/bugs/240533 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
