I use Youtube on deck in Firefox with youtube.com/tv in kiosk mode. Works really well, but I noticed even when I have a bigger screen connected I can only watch videos in up to 720p. It doesn’t let me select anything higher. Is that a YTTV thing or is there a problem in my setup?
Does changing the user agent work?
Pretending to be Chrome on Windows seems easy enough
Yes, there’s an addon for Firefox that gives you Netflix 1080p without any downsides, probably just by changing the user agent for Netflix.
Really shows how utterly useless the restrictions are.
