This is bad on Chrome too. Looks like a poorly designed website.

Nothing really obvious stands out for the JS time. Mostly time in JIT code.

Thanks for attaching that info -- though, bugbot may have been a bit overzealous in requesting it in this case.
Given comment 2's observation about this affecting other browsers as well, I'm not sure it's worth spending too much time investigating this as a Firefox bug; it sounds like the site is just doing a lot of work (perhaps unnecessarily/inefficiently) behind the scenes.
Reporter, are you seeing other browsers handling this site substantially better than Firefox? If it's similarly bad everywhere, then your best bet would be to get in touch with the folks who run the site.
I thought this could be an issue affecting Firefox and my hardware specifically (and Mayank has a similar CPU), but I can reproduce this issue with Edge too.
Bug 1902867, on the other hand, only affects Firefox.
This has now been corrected (by reducing the number of data points in the chart.) Thank you!
