Force lock Prime Video's video quality to the highest
< Feedback de Prime Video Force HD
This UserScript is only designed to lock the highest video quality and disabled automatic quality adjustment based on network speed.
If you are using Linux, first use another browser extension that modifies the User-Agent (not UserScript) to simulate a Windows platform and unlock 1080P playback. Since UserScripts can only modify the page content but not the User-Agent itself, they cannot achieve this on their own.
It doesn't work on Linux. From Google Chrome's console: "video set max bitrate: 3001000 bps (960x400)" -> "https://imgur.com/4aHUtqQ". It seems the script tries to force the max quality but in the end, I end up with the same quality as I was before using the script.
