It's a cool idea but it is laggy to the point of unusable on my Android phone running Firefox (it's a budget phone but I don't have this issue with any other sites).
Also Firefox on mobile, and I have zero issues (on this blog or the last linked one) on a pixel 4a.
Perhaps it's related to android version, Firefox version or constraints imparted by your budget phone, but it's not a mobile layout//Firefox specific problem as far as I can tell (and I have like a dozen add-ons installed now that we can install from the full Firefox catalog).
