The results are not that much surprising.
YouTube, owned by Google, is optimised for their browser, hence chromium-based ones perform better.
Would you care to try examine performance:
1) On another platform – not YouTube – with videos (may be already done as hinted by your text “when I was watching other videos as well.”)?
2) Change user-agent (via an add-on) for A) FF -> Chrome and B) Chrome -> FF?
3) Turn off HW acceleration in Chrom* (Settings -> System)
4) Tinker with FF Preferences -> Performance; when I un-tick the “Use recommended performance settings”, option with HW acceleration with adjustable “Content process limit” appears.
