Geeze that's going to be a real doozy. Generally Smart TVs or Smart anything are a bad idea. Just use a traditional computer, either desktop or laptop your choice.
I mean okay Smart TV, so we have something that's always going to be vulnerable and running outdated software and which you can't easily upgrade, except whenever the company that created the Smart TV feels like pushing some forced upgrades through. Expect all software to be very old and very vulnerable versions before long.
Then you're using Safari browser? That's well-known to be one of the worst browsers right up there with Internet Explorer. Even people who use Macs typically don't stick with Safari as they get fed up with it and install and use something better, like Firefox or literally anything else (except Internet Explorer).
And Safari doesn't even exist for Linux on desktop computers that I'm aware of, but maybe that's different on a Smart TV. Regardless that's not something you want to be using.
Yeah I just really don't see this getting fixed.
Linux? Cool. I use that. Smart TV? There's your problem. Safari? There's your double-whammy.
