I've been using Hoxx (with Firefox) for a while too. Great for getting UK telly.
There's a VPN add-on called Beebs that works on Chrome browsers. But with Opera, there's an add-on that enables other chrome add-ons
and Beebs works that way.
The Beebs name comes from BBC but if it works for BBC - and it does - then it ought to work for other things...at least for UK sites.
