Let me add a couple 100 more to that count. Did you know that netflix doesn't support resolutions higher than 720p on windows/linux? You could subscribe to the 1080p plan (like me) and the players will stream 720p videos to you with no indication whatsoever. The only way of checking the netflix video resolution is `document.querySelectorAll('video')[0].videoWidth`. There are FF extensions but they don't work for every title.

I only noticed when I got to the third act of annihilation. https://www.youtube.com/watch?v=uBsJgceM0KI&ab_channel=Prime...
I have been using for over a year https://github.com/vladikoff/netflix-1080p-firefox and works fine. But, I see now extension was removed from FF extensions page.
If I knew where to get the one I have installed, I'd send it to you people.
