Finally. For a long time it has been quite embarrassing that playing video on a modern laptop drain the battery like nothing else. Looking at the CPU usage shows just how bad it is. At the same time, mpv has been able to play the same videos for years with hardware acceleration. The only reason FF hasn't implemented it was because they were worried about it failing on some systems. Why they couldn't even have enabled it using a flag I don't know.
