It's not clear to me from the profile what is using all that CPU. It looks like an AV1 video is being played, which can be CPU heavy (as hardware decoders don't exist). However, the decoding process isn't using a huge amount. If different videos are being used to test it may result in big differences in the CPU values.
The about:support shows that the hardware video decoder has failed in the past for the gfx card and the currently installed drivers. This would lead to software decoders being used for such videos.
It would be helpful to know if the same codecs are being used by Fx as Chrome when this is an issue. The user could check by right clicking on the youtube video and selecting the "stats for nerds" and copying the codec value onto the thread.
