The websites I called Blivetware are shitty on all the browsers I've tried. I guess it's truly YMMV...

Your website doesn't have to have "shitty poor design" for it to lag FF. Compare scrubbing in this React player in Chrome and Firefox: https://hsreplay.net/replay/WpWzqzkCHTGdEmbguHUoiC
It comes down to issues in the Firefox JS/DOM engines.
