Why can't I watch HD videos?

When I am watching videos on Youtube, I only have the 360p option for video quality. Also, when I fullscreen a video on other sites, it stays as 360p. It used to switch to HD. On other browsers everything seems normal. I've got the latest version of Firefox.

hi reevesCFC, in case you are using a Windows 10 N version, you might have to manually install missing codecs that are necessary for HD media playback on the system: Fix video and audio problems on Firefox for Windows N editions
