Well look at it from Netflix's perspective. You are in no way an indicative normal customer. They don't support certain browsers, because there is no need to. Privacy hiding VPNs are used to evade content locking as part of Netflix's business models/licensing agreements, so why would they allow your privacy hiding vpn? I'm not agreeing that they should do these things, but you are approaching a service from a very standpoint, and I can understand why your experience is less than optimal. Being a ubuntu/debian user you must have encountered this before righ ;)
