I support every user's right to use whatever browser/ version they like. You could probably submit a report via /Special:Contact/bug, and after that it will be out of your hands.

You might point out to your friend that they'll probably have both better security and performance on a newer version, though.

Note that FF12 isn't on the list of /Help:Supported_browsers.
