Talking about tv's and browsers, the best option I ever had was to connect a spare desktop pc to my tv set, together with a wireless keyboard and mouse.
It was infinitely better than any Firestick or smart tv as I could browse easily, download anything I wanted, and sit back on the sofa and play Virtual Pool 3!
Sadly, the motherboard went recently, so I removed the whole pc from behind the tv, but I'm considering a replacement as it was so useful.
